Canon AV1

I now have a Canon AV1 with a shutter problem. Can I fix it? I’ll have a good go…

What the listing stated:

This camera is in very good overall condition. Some light signs of use but this is generally minor. The light meter is responsive when you press the shutter button down. However, the shutter will not fire. Spares or repairs only.

EBay

I’ve just paid £8:98GBP for this camera, and I believe this is a great price for a piece of camera history. The AV was introduced due to there being a demand for aperture priority at the time, whereas its Sibling, the AE1 was purely shutter priority. Later cameras would come to incorporate both systems. This one has a known problem with a stuck mirror – it won’t fire and I think I can easily sort this problem. Well I hope I can.

The Canon AV1 I have just purchased

Here’s a little information about this camera:

The Canon AV-1 is a 35 mm single-lens reflex camera with an FD lens mount, introduced by Canon Inc. in 1979.

The AV-1 is very similar to the 1976 AE-1 but provides aperture priority autoexposure rather than the AE-1’s shutter speed priority AE. The camera is not capable of fully manual exposure. Canon’s international distributors, particularly in the United States, had clamored for such a camera because competing brands offered mostly aperture-priority cameras and some preferred it. The AV in the name referred to the type of autoexposure; Av (Aperture Value) is a common abbreviation for aperture priority.

When this camera appeared, a new range of FD lenses was introduced, with instant mounting/unmounting of the lens. This is called the New FD mount and does away with the older type of mounting ring which was fitted on to the rear of the lens and was awkward to use and needed two hands, to a newer, easier system whereby the user lined up the red dot on the lens, with the red dot on the camera and simply turned the whole lens clockwise until it clicked into place.

All the other AE-1 accessories fit the AV-1.

Wikipedia

I’ve decided to collect all of the Canon “A”Series of cameras, and this adds to my current collection that consists of an A1 and an AE1. There were I believe, six cameras in this range and this current camera will be my fourth. Here’s a list of the “A” range of cameras below. I have highlighted with an asterisk all that I currently have at the date of this blog post being published:

Assessment:

The original listing description does not match the issues that I have found. It originally stated that the light meter is responsive, it isn’t. It also stated that the shutter does not fire, it does when a battery is installed. The battery level indicator in the viewfinder does work when the check button on the camera is depressed. However when you focus the camera and half depress the exposure button to get a meter reading, the needle in the viewfinder doesn’t respond, this is the only real issue I can see, I guess the seller must have been looking at another camera as he wrote the listing for this camera.

Battery level reading in the viewfinder

All settings appear to be working as they should, the “B”setting allows me to scroll through the “f” stop settings to see the aperture leaves working as they should. All “f” stop settings appear to work on the auto setting.

Camera appears tidy but grubby

It’s a smart little camera, this a tidy example of this version with no dents, dinks and just some very fine scrapes on the base as you’d expect from a camera fast approaching 46 years old (1979-2025). It’s a bit dirty and needs a good clean inside and out, the light seals are in a good state and not requiring replacement or repair just yet, however the mirror bumper has deteriorated and this will need replacement.

The shutter curtain is in a good and untouched condition.

I’m going to research issues with the exposure indication, and I will incorporate my findings within the repair section.

Repair:

I thought, perhaps the camera is suffering from lack of use? It certainly is probably some considerable time since this camera was last used. Firstly I’ll try exercising all the controls that affect the exposure reading, including the mode dial, film speed dial, aperture ring, etc. I’ll work them backwards and forwards a few times to see if this helps to clean the variable resistor tracks inside from any surface contamination. When the FD lens is attached you must be mindful that the “A” setting on the lens is not used and that the f stop settings are used in a manual manner, lens auto is not a function on this camera.

Auto shutter on camera
Do not use the “A” setting on the lens. It doesn’t work

To be honest, this did seem to work sort of. The needle has moved off the bottom a bit. The ASA setting was on 100, so I put it up to 1600 as it is quite a dark day and the sensitivity of the light sensor would be reflected better at this setting. It moved a bit but I wasn’t totally convinced that this indication in the viewfinder reflected the true light situation.

I set a higher ASA for testing

There’s also a small, silver push-button just inside the lens mount at about the 4-5 o’clock position. If you press this in and release it a few times for the same reason, as exercising the dials as I did above, it is just like exercising a body part and keeping it supple. Leave items like this, designed for high usage redundant for a while and they soon seize up. it has also been known to assist with getting the needle indication working after a long lay off.

That silver button, highlighted

(A little bit of trivia here – this button is normally used for the lens to inform the body of the lens’s maximum aperture. This information isn’t needed on the AV-1, but Canon included it anyway for some reason, and it does affect the exposure.)

And combining these actions, moving the settings dial and the button inside the lens mount seems to have revitalised the light meter and I’m now quite confident that it is working as intended. It was just lazy due to low use and needed a bit of non invasive intervention to get it working again. And non invasive intervention is always a good thing. So with the setting back to 200ASA I was able to show the meter working in this very short and basic video below.

A brief video showing the meter needle moving

I’m confident that the metering issue is now sorted so let’s get that new mirror damper installed.

A lot of dirt came off of the area where the replacement damper had to go, it had completely deteriorated and took quite a bit of cleaning.

New damper in place
Dirt that came off, and replacement damper ready to go into place

Now in place it has silenced the mirror movement somewhat, and will provide some longevity as it moves into the twilight of its years. It will be good for many more rolls of film yet. Whilst in the lens area I have cleaned the mirror and prism, and given the area a good blow through and put the lens back in place to seal it all up. It is now clean internally. I have a couple of body caps on order that will assist with storage when the lens is removed.

Just a final clean with some cockpit cleaner, and this camera has come up lovely, I’ve tested it on a Power winder “A” as well and it sounds just so good and “retro”. It’s perfect.

Result:

Well. I now have another lovely example of one of the Canon “A” range of cameras to add to my collection. This brings my current total to four out of the six available, two of which are still currently under repair. For less than £10:00GBP it is so easy to own a piece of photographic history. I have been lucky here that the work that had to be done was non intrusive, and to be quite honest was just basic everyday maintenance. The only real work of sorts was installing some mirror damper felt, of which I have plenty of stock. Cleaning was quite intensive but the overall result is amazing.

Looking amazing compared to what arrived

I will eventually run a roll of film through for a final quality check, however I have such a backlog it will take me a while. When I do however run that test roll I will post a link here:

Really pleased with this repair, and the fact that another lovely old camera has been saved from the scrap heap and been given a new lease of life.

Thanks as always for passing by. It is as always, very much appreciated.

Canon EOS 500N

A nice entry level camera, from the mid 90s, now back in working order

Here I have a very basic, entry level camera made by Canon. Produced between 1996-9 this camera is currently between 26 – 29 years old. These cameras don’t have the traditional identification number printed within the film spool holder that the older cameras had, hence the precise manufacturing date is difficult to confirm.

Canon EOS 500N

This is a camera passed onto me by a good friend and professional photographer, Jon, as can be seen in this post: Cameras…i need more!

I believe this camera was previously used by a large photographic organisation, to teach staff and students wishing to learn traditional 35mm film photography techniques. It was a training camera, at entry level specs.

It is a very good example of this model of camera, and despite its simplicity, low cost appearance and feel, it is in a very good condition cosmetically.

Here’s a little information about this camera:

The Canon EOS 500N is also known as the EOS Rebel G in the Americas or the New EOS Kiss in Japan. Sometimes it’s referred to as the EOS Kiss 2 as it followed the release of the EOS Kiss in Japan. This camera was released in 1996 and replaced the EOS 500. The Japanese version of the camera had the date back as standard. Its successor was the EOS-300 / REBEL2000 / Kiss III, released in 1999.

The body of the Rebel G is plastic, weighing 370 g (13 oz). The only colors available were black or a mix of silver and black. The Rebel G has an EF lens mount making it compatible with any EF lens. The viewfinder offers a 0.7x magnification, 90% coverage, center auto focus, wide auto focus and many more. The Rebel G shooting modes consisted of 6 basic modes, full auto, portrait, landscape, macro, sports and night scene. It also has 5 advanced modes, P, Av, Tv, M, A-DEP. These modes would continue on in the Rebel G series. The camera features a built in flash, and can shoot at 1 fps. The fastest shutter speed with flash was measured at 1/90 of a second.

A few new features include compatibility with ETTL type flash. It still has the same 1/90 of a sec sync speed of the previous model, but when equipped with a Canon Speedlight such as the 380EX, 220EX it can be used at 1/2000 of a sec. Focus has improved a bit as as a AF assist light is now available. Auto Exposure Bracketing (AEB) can be use from -2 to ++2 in 1/2 stop increments. The command dial now has an easier to access night scene mode. The body is able to use the BP-8 vertical grip that can also accept four AA batteries.

Assessment:

As Stated, this camera is in a good cosmetic condition with no sign of dents, dinks or wear. Considering this was a camera used in training I can only presume the students were extremely careful and respectful, or it was lightly used. Having worked with some of these students myself, i very much suspect, it’s more than likely going to be the latter option.

There is another such unit I have of this very same camera however that is damaged with a faulty screen that requires replacement and that will be dealt with in a future post. Meanwhile, let’s get back to this one.

A sticker on the rear

There is an old ownership sticker on the rear and this is one of those old vinyl type ones that will be able to be removed, but just may take a little while, as they are brittle and break off into lots of little pieces that go everywhere.

The battery chamber is clean and there are no signs of contamination. The screen is clear and does not show any bleed, though I haven’t powered it up just yet.

Clean battery chamber
No screen bleed

The film chamber, back pressure plate and shutter curtain all appear to be in good order. Again I will further test this when I put some batteries in and run a dummy film to check transport.

Curtain and film chamber appear fine
Back pressure plate and door working fine

The unit is quite grubby and dusty, the mirror is dirty and the prism is as well. initially all looks good. Batteries, and the dummy film might tell us something different.

Repair:

Let’s get that sticker off the rear, a little soak in IPA to soften things up, and then using a small plastic modelling spatula to gently get under the label, I was able to remove the sticker relatively easily. If I’d used the metallic option I may well have scratched the casing. I’m happy that this option has worked well for me. A final clean at the end with some car cockpit cleaner should bring the detail out nicely.

Sticker now removed

Let’s get some power in, and fire this unit up. It takes two CR123A 3v lithium batteries.

CR123A batteries
We have power

Batteries in, and everything lights up, all menus function and as stated earlier their is no bleed from the LCD screen.

I load the film in and it instantly winds the whole film on to the take up spool. Here on the display, you can see that this roll is 24 exp and it has wound fully on to the take up spool. I fire off these 24 exposures to check the shutter and that fires fine, film transport also works well and the final rewind of the film at the end also works. In a nutshell, this camera works!

Film in and film out

I clean the prism and the mirror with a soft swab and you can just see the dust and dirt lift. A final brush over with a bulb blower completes this task. The internals are now clean.

It just needs a very thorough exterior clean and polish.

Result:

I’ve cleaned the exterior and used some ceramic cockpit polish to finish it off, I must admit it’s looking very good.

Here I have a nice little camera packed with features that will make a great camera for someone to learn the basics of traditional photography with. However, it’s remaining in my collection for the while.

Looking clean and presentable
From all angles a lovely clean example, operating just as it should

I’ve cleaned the camera throughout and used compressed air to finish the clean prior to sealing it from the elements. It’s yet another camera that I need to test, another one that needs to have a film put through it for its final test, however I am 100% confident of it’s capabilities and the fact that it operates just fine and all its settings, buttons and controls are doing exactly what they should. When I do get to put a film through, I will link to it here.

Another successful restoration and return to use of another old camera that had been put to one side. Not that this one really required a lot of attention, just a bit of servicing and tlc.

Thanks for passing by. It’s always very much appreciated.

Canon EOS 10

An old EOS 10 was in need of attention. And I was able to lend a helping hand

Here I have a Canon EOS 10, a quite superb little camera. The date code within the film barrel is HE1213, indicating that this camera was manufactured in December 1990. At the time of manufacture this camera sat firmly at the top of Canons camera tree only surpassed by the EOS1 professional camera that had been released the year earlier in 1989.

My EOS 10 35mm SLR

This camera was amongst a selection of cameras and equipment passed on to me by a good friend and professional photographer as can be seen here: Cameras…i need more!

Here is a little history regarding the EOS 10

The Canon EOS 10 is an autofocus 35mm SLR introduced in 1990. The model name was EOS 10S in the Americas, and EOS 10QD in Japan. There was a commemorative metallic-silver version introduced in 1991 to mark Canon’s 60 millionth 35mm camera sold.

The improvements over the original EOS cameras are a newly improved autofocus sensor. Focus modes include One-Shot AF for non moving subjects and AI Servo AF for moving subjects. It is able to detect and switch automatically between the autofocus modes. Shutter ranges from 30 sec. to 1/4000 sec., with B. X-sync at 1/125 sec. Similar to the EOS 750, is has a built-in flash with a guide number 12 (at ISO 100). It uses one 2CR5 lithium battery and weighs approx 625g for the body without battery.

Camera wiki.org

Assessment:

One of the nuances introduced on this camera was the barcode option. Introduced at a time where barcodes were starting to creep into our life, in a knock at Minolta and their use of specific expansion cards for specific scene settings, Canon thought it would be good to utilise barcodes that you could scan, to automatically set your camera with these options without expansion cards. Needless to say it didn’t take off and was soon dropped from later camera production. It was a sign that the development teams were looking for advancement opportunities.

That barcode mode – soon forgotten

These cameras are available at fairly reasonable prices now partly due to the dreaded sticky rubber grip issue that tends to send buyers running for the hills, god knows why, it’s an easily remedied issue that just takes a little time and patience. I did a previous post about cleaning these cameras here: Sticky, Rubber camera grips it’s all down to the polymers in the Vulcanised rubber breaking down and reacting with hand sweat and other stuff. Have a read, and never throw away a camera just because it’s sticky.

This camera has some stickiness but it is not an advanced case. It will still be cleaned in the same manner, to prevent it developing any further.

The camera is just a bit dusty and in need of a good clean. The mirror is dusty and needs cleaning, a blow out of the interior should suffice as the shutter blades are opening and closing with no issue.

Inside clean shutter blades are ok
Film plate unmarked
Mirror is dusty and requires cleaning

The battery is a lithium 2CR5 cell. The battery chamber is clean with no signs of battery contamination, this is a very good sign. When placed into the camera the screen comes on, is clear with no damage. A lens put on the front confirms that auto focus can be achieved and the camera fires and winds as expected.

To be quite honest, there doesn’t seem to be a lot wrong with the camera. It really seems to be just a clean and maintenance issue. I’m going to give the camera a thorough look over, dust and clean, a thorough clean of the external rubber and finish it all of with a good exterior body treatment. I will then run a roll of used film through to check the DX reader is working, as well as the transport system. Fingers crossed nothing major raises its head during the repair process.

Repair:

Straight in and at the cleaning, and to be honest the rubber wasn’t too bad. I only used two applications and not a lot of dirt came off on either. After it has dried, it does feel a great deal better.

Heavy cleaning, wasn’t that heavy

The mirror has cleaned up nicely, so has the prism above it, however whilst in there I noticed that the mirror damper felt was failing, so this I have now removed and will have to replace prior to using as I don’t want to cause any further damage.

The missing damper felt area, highlighted in red

I’ve had to order some new material that will hopefully be here shortly, as my supply, as is always the problem lately, is in storage with all my other gear pending this house move that will probably never occur. it’s a real pain in the butt not being able to access your most required kit. Hey ho.

The light seal has arrived, and so I start by getting the damper felt put in place. First I cut it to size, remove the sticky back paper and just wipe the sticky bit with some water, this allows me a little more time to reposition it before the adhesive does its work.

Cut to size
Dampen the adhesive
Then put in place

Below is a very small video with me putting the camera into manual mode on a single exposure setting to test the actual worth of the damper foam.

All working fine

I’m happy with what has been done so far.

Strap cleaned and restored

I’ve even given the neck strap a good buff up, the rubber on it was almost white rather than black, a bit of a clean and a polish and it’s now been restored to it’s original glory.

With the new damper in place it’s now time to run a film through it, I have an old test film I use for this purpose, I’m going to set the camera to its highest shutter setting and just run the whole roll through in quick succession to check the transport and rewind.

And here is that test, it went super fine and the full roll rewound at the end.

Transport works just fine

I’ve tested all settings, shutter speeds and functions including the flash and all is as it should be. I’m happy to say that this camera appears to be in full working order.

Now for the final clean and presentation.

Result:

Well, a little bit of car cockpit cleaner has done wonders. It looks beautiful and has a nice aromatic smell as well. I know I’m biased when it comes to cameras but I think this is an absolute beauty.

All polished and looking fine
Covered from all angles looking resplendently clean and tidy

I’m really pleased with this camera, I’m heading out later today to watch a relative play football and I’m going to take this along to grab some snaps with an expired film from 20 years ago. It will be a good final test of the capabilities of this camera, and should finalise its renovation. It’s been a great camera to work on and is yet another worthy addition to my collection. I will post the photos here when they are finalised. Canon Eos 10 test shots

Thank you all for passing by, it’s always most appreciated.

Sticky, Rubber camera grips

Anyone who has had an 80s/90s/00s camera through their hands would have experienced this at some point. During this time period many if not all camera manufacturers went through the phase of putting rubber hand grips on their cameras. Aesthetically pleasing, and ensuring a good grip of your new “Expensive” toy. I guess, they thought they had got it right. But as with all these good ideas they often come back and bite you right on the bum at a later date.

My particularly sticky Nikon D70

Ok there were probably no recalls regarding this issue, it’s just affected the price of these goods on the second hand after market, and more than likely a perfectly good unit has most probably gone to landfill for no other reason than “Feeling sticky”

Let’s look into the reasons why this occurs.

It’s pretty much down to a process called Vulcanisation. Vulcanisation is a chemical process that hardens rubber by cross-linking polymer chains, making it more durable and elastic. This process, often using sulfur, heat, and other additives, transforms natural or synthetic rubber into a material with improved properties like resistance to heat, cold, and deformation. 

However after many years, the process begins to break down, this causes the rubber to become sticky and in some cases the rubber just breaks down causing traces of rubber dust all over the place. Add to that the normal oils from fingers and palms and the stickiness then becomes highly noticeable, and makes for a very unpleasant experience.

We can’t stop the progress of the degradation, we can however do something about the sticky state, maintain good quality and make the use of the item as pleasurable an experience, just as it was when first purchased. Many believe the stickiness is down to the way the item is stored, and it not being used on a regular basis, as there is plenty of evidence out there of similar aged cameras not suffering from the issue at all, as they are used daily, namely by professional types where these cameras are tools of their trade.

It involves some work, and patience. I am writing this post as I have 8 cameras that i am currently working on, all Nikon D70/D70S and they all have this problem, and they date from 2004.

A load of very sticky Nikons

I use a process that you will easily find on line, the most simple process and it involves using a substance called Isopropyl Alcohol, my one is 99% pure, (also known as rubbing alcohol) I don’t think the purity of 99% is essential but i use it as i have plenty of it around, what with all the circuit board work i do, and the cleaning they also require.

Some people have had results just using a dry cloth and no chemicals, patiently rubbing and rubbing, some for a few hours at a time, until all the mess is removed. If that’s the way you wish to go then fine, i haven’t got the time for all that, i’ll be talking you through the way i do it below, with a chemical.

My technique is simple, lint free cloth and some cotton buds are all that i use, along with a tissue wipe (Such as armoral, or a car cockpit cleaner solution with a dry cloth) and a cocktail stick to finish. The reason for the wipe will become clear at the end.

My Guinea pig for today is a Nikon D70 I have requiring repair. It is a particularly “Sticky” individual and will be a good candidate on how to deal with this sticky situation. This is the process I use on all my equipment that has rubber such as this as part of its structure. It’s worked for me for many years, some people say that it will need doing again after a short while, that’s never been the case for me, and there are a number of documented cases on line where six years after this treatment has been done, there is no repeat of the initial problem. The rubber remains good.

Using a small amount of IPA on a lint free cloth gently wipe the area of concern and you will see the stickiness start to lift, it looks like a glue.

A glue type deposit
Gently wipe
The dirt is soon lifted

Make your way around the whole camera paying particular attention to those really sticky areas. The IPA evaporates really quickly so you get to see results really quickly. If after one try the stickiness remains then try another application. A good indicator is that when you use a fresh part of the cloth, you see less dirt come off with each application. When you put an application on and come away with a clean cloth, your job is done.

The cotton buds for the corners
Second application
The dirty cloth and cotton buds

The cotton buds are used for getting into those inaccessible crevices you can’t get into with the cloth. As before as they stay cleaner and pick up less dirt your work is done. All this cleaning and moving about of dirt sometimes transfers the dirt into creases and joins between the rubber and the camera body, this is what the cocktail stick is for, to get into those small gaps and scoop the dirt and debris out. Complete with a final application of IPA in this area and the dirty work is now done.

Now earlier I mentioned about using Amorall wipes or a car cockpit cleaner. Sometimes this process can dull rubber, as you have just removed the layer that was providing the gleaming glory back in the day. You can’t have it all your own way but a good quality interior dashboard cockpit cleaner really does add some shine and life to that old camera and really does do a good job of restoring it. I use Auto Glym interior shampoo on a lint free cloth and apply this by gently applying all over the exterior of the camera. It is now exceptionally clean. A quick rub over with a dry cloth once this is dried and what more can I say? This is a different camera, looks stunning and has lost all trace of stickiness and dirt. Now it has that extra layer of protection as well, it’s now a pleasure to behold.

The finishing touch.

This little task probably took just over 20 minutes to achieve and gives so much satisfaction to me as you can see a cameras appearance change in front of your very eyes, and anyone can do it. No camera deserves to go to landfill just because it has this sticky exterior, it’s simple to do and can revitalise an old and much loved camera.

The finished item – stickiness now a thing of the past

I hope this has helped with dealing with the stickiness issue, if you ever experience it. I have even heard reports that a good quality window cleaner can also give similar results, but I’ve never tried it, so there really is no excuse if you have a camera in your ownership needing similar attention.

Many thanks for passing by. You legend👍

EBay

The Finepix S2 Pro

I’ve purchased three cameras as a job lot in an auction. All of them have issues but the issues have not been clarified. This is very much a “Suck it and see” auction where I get what I’m given. I’ve paid £24:22GBP for all three and that includes free postage. I’ve purchased from this seller before who is a bonafide Camera business based in South Wales. He has no time for faulty items though, quick in and out is his way of working, no time to fix stuff. I’ve got three good cameras in this bundle and this works out at just about £8:00GBP per camera. And where can you get cameras like this for those prices nowadays.

I’ve just read a blog where a guy had one of these cameras from new, and in 2002 he had paid £1550.00GBP for this camera. Wow, and here i am 23 years later paying the grand total of £8:00GBP for one. Even if I don’t get it working, I’m happy with that.

Now this particular camera had two issues in its lifetime that caused concern, and one of them meant it was pretty much game over, and that one was the CCD issue that used to plague this range of cameras. Fuji released a whole bunch of these cameras with a faulty CCD that had to be fixed under a recall. They built sufficient replacement CCDs to cover the recall and that was about it. There were no remaining CCDs left and at that point what was left had become as rare as hens teeth. If you suddenly developed that faulty a later date, then tough…you were stuffed.

Serial numbers affecting CCD problems are listed below:

Model Serial Number Range 

FinePix S2 Pro 31A127**~31A143** 

32A000**~32A039** 

33A000**~33A007** 

34A000**~34A004**

Fujifilm

The second issue was with a batch of these models that had a “bad” resistor in the power circuit that prevented lock up if there was a power spike, if this failed then the camera just stopped and you were stuck. There was another recall on the second issue but there is probably a lot of cameras out there that again weren’t part of this recall. And I guess owners were pretty fed up of recalls at this point and were off loading their equipment as quick as they could.

The serial numbers regarding the lock up problem are listed below:

Between serial numbers 24L00441 and 24L00680
Between serial numbers 24L01057 and 24L01256
Between serial numbers 24L01553 and 24L01863
Between serial numbers 24L10257 and 24L10608

My camera serial number

Above you can see the serial number for my camera. Thankfully my number falls outside the range of any of the cameras inflicted with either problem, so it’s fair to say (Fingers crossed 🤞) that I shouldn’t suffer with any of the known issues with this unit. In layman’s terms I think i may well have dodged a bullet here.

I did speak to the seller regarding the fault on this camera and he stated it was just a general error code on the top screen. There is a general error that arises occasionally regarding certain lenses where they have to be locked on their minimum aperture for the camera to work properly, however I’ve not attached a lens yet so this cannot be confirmed.

Here’s some history:

The Fujifilm FinePix S2 Pro is an interchangeable lens digital single-lens reflex camera introduced in January 2002. It is based on a Nikon F80 (N80 in the U.S.) film camera body that was modified by Fujifilm to include its own proprietary image sensor and electronics. Because of the Nikon body, it has a Nikon AF lens mount and so can use most lenses made for Nikon 35 mm cameras. It is autofocusing, with an electronically controlled focal plane shutter with speeds from 30 sec. to 1/4000 sec., built-in exposure metering and pop-up flash. Its ISO film speed equivalents range from 100 – 1600. The S2 Pro also has sound recording capability. The camera is no longer in production, having been superseded by the Fujifilm FinePix S3 Pro in February 2004.

Aside from the Nikon lens mount, the camera’s principal distinction is its 6.17 megapixel photo sensor. Known as the Super CCD, it is unique in having its photodiodes oriented diagonally rather than horizontally and vertically as in all other DSLR cameras. This allows the use of a sophisticated interpolation system that produces an output image equivalent to 12.1 megapixels. The apparent resolution of images in this interpolated mode lies somewhere between 6.17 megapixels and the 12.1 megapixel interpolated output.

A huge number of these cameras were built using a Sony sourced defective CCD that was subject to a recall by Fuji. The recall ended when the stock of these replacement CCD’s was depleted. There is word that no other stockpiles exist of this Super HAD CCD, making these cameras that are found with the purple or black tinted image problems extinct, only usable for parts. The Fuji F700 used a similar defective HAD CCD, but in 3.1/6.2Mp size. That camera has met a similar fate.

So let’s hope that we can get some pictures out of this unit. We just have to wait and see what arrives.

Assessment:

Well the camera has now arrived, and I must say it is in an absolutely beautiful condition. Cosmetically there isn’t a scrape or scratch, all screens are scuff free and it looks as if this unit has been well cared for. It just needs a wipe over to clean. The package is just the camera body with no extras such as a body aperture cover or neck strap, but who’s worried about that, they can be procured at a later date.

Nikon type F mount

These units are quite power hungry requiring a total of six batteries. 4 AA cells go in the base and two Lithium CR123A batteries go in the grip. These batteries work in unison, one set handling the basic camera functions whilst the other deals with the capture and processing of images. It’s a strange affair, loosely based around the same setup that was originally on their film based camera counterparts.

AA batteries
CR123A batteries

I’ve had to order the lithium batteries, however I can still get displays and Information using just the AA batteries in the base, basically it is semi functional in this situation.

The lens mount is a standard Nikon F mount, I’m going to have to search through my equipment to see if I have such a lens, I suspect I don’t, so I may well have to purchase a small lens purely for test purposes. I have some other Nikon repairs in the queue, so a lens to have for test purposes wouldn’t really go amiss.

The unit takes either a CF card type II or a Smart-media card (Max size of 2Gb on both) that is located behind a hinged section on the rear of the camera, these work fine and have no bent pins.

Media card ports at the rear

With batteries in place I get the full range of menus, and nothing comes across as suspect at all at this stage in the assessment.

The top menu – no lens attached to test

The top menu by the exposure button is the only “F” indication showing, I have no lens attached so this might be the reasoning for that, but if I do put the menu into manual mode I get the full range of shutter speeds and can even operate the shutter, the shutter seems to be working at all selected speeds with no issues as far as I can see.

Some of the shutter speeds available in manual mode

All other menus are available and I’m even able to format the CF card via the cameras menu. The picture you see on the screen was taken on another camera. It wiped fine so no issues here.

Various menus and the screen after a format was completed through the cameras menu controls

The camera seems to be working with no apparent communication issues as yet. When you try to use the flash it even informs you that you need to insert the correct batteries to test. As I’m awaiting the CR123A batteries I won’t be able to test the flash functionality until they arrive.

No CR123A batteries installed? – You can’t use the flash

As I have stated the testing can only go so far until I have the missing items in my possession, for me that is the two missing batteries and a suitable lens. I’m currently in the process of procuring both. Physically there is nothing wrong with this camera after spending a good couple of hours going over it. I’m quite comfortable with it and believe it could be a lens communication error or just a failure to read the instructions properly by the previous owner. All I need now is that lens. I’ll let you know what occurs in the repair section.

Repair:

To be quite honest it’s not really been a repair, it’s been more of a “pre flight check” to collar a phrase, going through all of the cameras capabilities and ensuring that they are all functioning correctly. As the camera was listed as faulty, and the fault was not identified, I have had to do many hours of testing and Investigation to get to this point.

I’ve done a bit of shopping and managed to buy a nice little lens from the Southern hospice group. Always happy to help a charity and secured this at a good price of £15:50GBP, and that includes the postage, for a Sigma 28-200 f/3.8-5.6 Ø72 Zoom Lens Nikon F Mount. There looks like a bit of fungus on the outermost optic, however I can always clean this if it’s too bad. If not I’ll just leave as is for the moment and keep it vacuum bagged between uses, I can always do a separate post on cleaning up fungus in a lens at a later date. (I have done a basic fungus clean in the past : Canon EF lens 35-80mm)

My new – old test lens

I wasn’t looking at spending too much here, as I only wanted a lens to test a number of Nikon repairs I have upcoming as well as this S2 Pro. This lens will fit that role perfectly, and be added to my collection of other lenses that I have that allows me to test a range of different camera products. I have also purchased an “F” mount body cover for the camera to protect the unit when there isn’t a lens attached to it.

The two CR123A batteries have arrived and have been placed in the handle grip. The warning that was there before the batteries were installed (see picture above) has disappeared and when placed in manual mode the flash fires just perfectly, no issues here.

The Lens has arrived. Good point is that it fits fine and looks good, and all electrical contacts are good. Bad point is it has severe fungus throughout, and is just like looking through a fog.

Severe fungus in the lens

I will do a separate post on cleaning this problem up in a later post. However I’m not overly worried at this point, I paid a very low price so it was to be expected, I’m not complaining to the seller who was a Hospice, they need the money and I can fix it so there really is no problem.

That lovely looking lens hides a problem

The excellent news is that the lens does exactly what it should. The camera indications are good, all working exactly as expected . However the pictures via the screen are extremely hazy due to the fungus infection on the lens. There are no black or purple casts on the pictures so I am quite happy that we haven’t inherited the dreaded CCD issue discussed earlier in this post.

Hazy days – Lens fungus

If I use the lens wide open and pop the camera into auto mode I do get an “ERR33” code and that is a communication issue between the lens and the camera. As I have stated earlier in this post, you have to have the lens set at its lowest aperture and locked for the error code to go. Fortunately this lens allows you to lock the aperture and once this is done the camera takes over the exposure when it is working in automatic mode. So as I also stated earlier, it appears the seller was probably not aware of this requirement/issue.

Result:

We have a fantastic working camera, it does all it was produced to do, it has its little quirks and oddities, but being familiar with these cameras and at least having some knowledge and awareness of how they operate is always a wise thing. Read the instructions and don’t just throw them in the drawer until you eventually sell the camera on as a damaged item, when in fact you were just lacking the knowledge on how it operates in the first place. Instruction manuals are good, they serve a purpose. Knowledge is king.

The complete camera with lens

This camera cost me £8:00GBP. That is a superb price for a camera of this quality even though it is now 23 years old. It has a lot of life left in it, and I can’t wait to get it out and give it a real test.

It’s a little beauty – And the lens that needs attention

So in theory I’m confident and happy that this camera is now in a fully operational order, it’s needed a clean, it’s needed a lot of research to find out how it works, and I’ve also downloaded the operating instructions and repair pack should they be required.

It’s taking pictures and storing them. It’s just the lens at the moment isn’t performing at its best due to its fungus on the optics issue. I’m keeping the pictures stored on the card to compare them with the new pictures that will be taken once I have another lens to use.

Once the lens clean up is complete, if I ever get around to it, I will link it through this post.

Edit:

As 12/7/25 I have purchased a newer higher quality lens without any of the above issues to be able to get some instantaneous results, and as I have about seven other Nikon cameras requiring testing, some with sensor issues, it was wise to invest in a better quality lens. I have purchased a Nikon 28-100mm AF Zoom Nikkor Lens G AF-d, in perfect condition and the post regarding it can be found here: Nikon 28-100mm AF Zoom Nikkor Lens G AF-D

A newer – old lens, much superior quality

As previously stated I will add photos in this post once the new lens arrives, to show the difference from the fungus infected lens to a decent lens. The old lens is still a work in progress and I will post about it again as a separate post once the clean up is complete. It will probably be a job completed once the long winter nights are back in situ.

Below are comparison photos between the old lens with fungal issues and this new lens:

It’s just typical for me to manage to make another post from an issue that has arisen from fixing a different item. But isn’t that life? Continuous improvement is a factor we come across on an almost daily basis, and if you deal with old items as much as I do, then there is always something else that needs repairing, something that requires your attention and I just love that. The ability to improve or make something better, gives such a feeling of achievement and accomplishment, and total satisfaction. And that’s why I write this drivel. It’s for me, it’s what this blog was originally set up for. It’s my journal of what I do.

Many thanks for following this post. You know it is always very much appreciated.

Fuji Finepix S1500

I purchased this item from EBay in April 2024 and have only just got around to finishing what had been a draft post put together all that time ago. I had written about it briefly in this earlier post Fuji Finepix S1500

A little bit about this digital “Bridge” camera

Successor to the S1000FD (at the time the world’s smallest 12x zoom camera), the FinePix S1500 is the latest in a long line of very compact SLR-styled big zoom cameras designed to appeal to those wanting a lot of lens on a tight budget. The big change is the inclusion of optical (CCD shift) image stabilization, making the long zoom a lot more usable in less than perfect light, and for the money you’re getting a lot of features – including full photographic controls and a 7.5fps burst mode (at reduced resolution) – in a lightweight package. Price on the market back in 2009 was £219:00GBP

DP Review

Assessment:

This camera was launched in 2009. The unit has arrived and is cosmetically tidy, however when you open the battery door the issue is obvious, two of the contacts are badly corroded and despite some initial cleaning there is no continuity and no power present. The unit is very much dead and not working.

A tatty and unloved camera

The issue with these units is that the power chambers are hard to access and to get to the point where the battery connectors are, you have to remove the powerboard assembly and this involves de soldering a number of points. There does not however appear to be any major signs of corrosion on the visible side of the board, when it’s removed it may reveal a darker issue hidden below.

Power board assembly

It’s going to be no easy task but I may look at running six volts from the bench power supply to a point on the power board assembly to see if I can breathe life into this camera. I don’t want to waste time in the battery terminal area if there are issues elsewhere on the unit.

The corrosion on this camera is horrendous

Repair:

Looking at the boards again I am not going to pay them any further attention. The contamination has not reached under them and is isolated to the battery chamber so that’s where I will concentrate on.

I’ve started with the contacts on the battery door, as you can see above, they are particularly bad and have no continuity through them.

Corroded door
Contaminated contacts
Badly corroded
All clean

When reassembled the door section looks good, it will just need a good clean at the end.

Before and after

Rather than dismantle the whole camera, and because I know there is no contamination on the main board I was able to get down into the battery chambers with a steel braid pen that I have, that allows me to gradually scrape off the contamination. Followed off with a good chamber clean of Isopropyl alcohol, I was able to get the remaining acid contamination out of the camera.

Attacking the contamination in the battery chamber

Result:

Once I did all of this I paid some more attention to the exterior using some car cockpit polish, this removed those horrid white sweat marks you see on the faux leather coverings of these older cameras, and it came up quite well and had a lovely vanilla smell to it .

Looking mighty good….and clean
Polished

I have turned it on and hey presto we have life. Everything is working as it should. It’s a 10 Megapixel camera and I have a 1Gb Sd card installed and it is taking pictures as expected.

And it works

Nothing more really to say about it, it cost me about £6:00GBP spares and repairs as it was totally dead, thankfully we’ve managed to get it working instead of breaking it up for spares that would more than likely never be used anyway.

Finished item

This unit is of no real use to me, so I will get it up to our local Hospice shop for them to sell on.

LOROS our local Hospice

Even if they only get a few pounds for it, it will benefit someone who needs the help and assistance.

So another item saved from the scrap heap. Might be of use to someone.

Thanks for passing by.

Werra 1 stripdown and rebuild

I recently purchased this camera and wrote about it in a previous blog entry Werra 1

I’ve commenced taking the Werra to pieces. The winder was not working and the shutter was not firing. Before starting this work I’ve viewed this page at Everything Vintage where they have recently carried out a full strip down of the Werra and you can view the page HERE, it’s all great advice.

Getting below the top plate was relatively easy exposing the mechanics from 58 years ago, I don’t think it’s ever been opened in all this time. I always love to see the ingenuity that went into these old cameras in years gone by.

Werra 1 stripdown

The internals look dirty in the photo but to be truthful I don’t think the lighting is doing it any justice, yep there is a fine oxidation coating but it’s at a very acceptable level considering its age. When I get to the point of dismantling as much as I can, I will start to clean and lubricate these pieces. But at the moment my goal is getting to the shutter.

Werra winding system – shutter not working

In the video above I’ve managed to get the shutter cocking using the lens ring, however the shutter actuator does work intermittently, but there is no movement of the shutter (Or is there…)

The only reason I ask the question above is that after reading the “Everything Vintage” link in the first paragraph it appears there is a second shutter that closes the light path to the film back when you wind on. When you are ready to expose the film this shutter opens and then there is a second shutter that controls the exposure. if you watch the small video above I think it is this shutter you can hear when I wind the camera on. Hopefully this one is working, I just need to get the one on the rear working, and for this I need to remove the lens from the housing. To do this I need a tool I don’t currently have but have now ordered. More to follow when the lens ring removal tool arrives.

Lens ring spanner

The lens ring spanner has arrived, the ring is being right stubborn at the moment and Im struggling to release it from its 58 years of rigidity. I’m tired as well and don’t want to cause any damage to the shutter so I’ll come back to this later.

18 hrs later, I’m rested and have another go at releasing that lens ring, this time I’m successful and I manage to release it. Sometimes it’s better to sleep on a problem and approach it with fresh eyes rather than continuing whilst tired and prone to making mistakes.

Werra Lens ring removed

With the lens off the body, the shutter cassette can now be removed. It amazes me just how intricate this cassette is and the workmanship that must have gone into it. I’d estimate at least 10 small cogs and a number of tiny springs with levers and pivot points, amazing really considering it’s about 60 years old. It’s amazing how modern technology has advanced.

Werra lens breakdown
Werra shutter module
Werra lens – another shutter on the rear

It takes some time getting into the shutter cassette as there are springs and things flying off everywhere, you really do have to photograph everything you do just to be able to check what goes where and how.

Inside mechanism – where is that spring from?
Complexity of the shutter mechanism

The shutter itself is rather clean apart from some fingerprints on the shutter leaves that must have been from years ago. I have cleaned this down with IPA and then used some finely ground carbon (pencil lead) as a dry lubricant and this has got the shutter moving just fine.

Werra shutter after being lubricated with carbon

I’m now starting to reassemble the lens and shutter as I’m happy that there is nothing else restricting the shutter and it is now moving quite freely. I will clean the camera as I progress and put some watch lubricant on the mechanics that are external to the lens and shutter assembly.

Werra 1 rear
Werra 1 base
Werra 1 top
Werra 1 front

Well it’s all been reassembled and is now back in one piece. It looks good, the shutter works fine and I’ve now vacuum packed it to go back into storage. I won’t be firing up a roll of film on it yet as I don’t have the time to did so at the moment. I’ll probably save that until the summertime when the weather is more favourable. I’ve really enjoyed this restoration even though at times it was very frustrating. This rebuild has taught me patience, or at least that I need to have more patience and just take my time. Intricate jobs on such old equipment need a clear head and a lot of concentration. I’ve learned my lesson and will endeavour to remedy that situation in my future dealings with such equipment.

Modified Sega game gear 2110-50

You may wish to refer to this post: Sega game gear 2110-50 where I purchased a non working Sega Game gear and brought it back to life.

The (I thought it was repaired) Game gear

I’m now ready to do some modifications on this unit, and I will save the replaced items for use on later projects.

Pretty much every Game Gear that was ever produced (and that is approximately 10.6 million units) has suffered with the dreaded (Capacitor plague) that I have discussed in an older post. The first job that is recommended to be carried out when purchasing an old Game Gear is to replace the old capacitors, it’s quite an easy task and nine times out of ten will remedy any issues that you have and allow you to continue gaming for years to come.

However there are other issues.

The screen is an old tube powered system that is exceptionally power hungry, you can replace this with much superior LCD versions, I’m withholding from doing this at the moment as I want to get as much use out of the old screen, and to be honest my unit doesn’t require replacement just yet, there’s still life in the old girl. I’m sure that this will be a future project though.

Occasionally after doing the capacitor replacement on the power board, other components such as a small IC and three transistors that control voltages across the system, start to misbehave causing the unit to switch off after just a few seconds. This is currently occurring with mine and I am intending to replace these components to see if this sorts out my issue. I have also ordered a replacement power board from China that is a fraction of the cost of a European one, it may work, it may not but if the change out of components dosen’t work at least I’ll have an alternative option.

There are a few checks we can do prior to replacement of these components on the power board that will confirm the various voltages required by the system. It’s best that these tests are done prior to diving in head first to replace them. You could be just wasting time. You may need a new power board or maybe even consider converting to a rechargeable battery system. It’s all doable.

Expected voltages – photo courtesy Retrosix

Here are the results from my test of voltages on the power board, I’ve injected 9v via a bench power supply to the battery contacts on the board:

  • At the 34v pin I had 0v
  • At the 9v pin I had 8.9v
  • At the 1.28v pin I had 1.28v
  • The three ground pins read as ground
  • At the two 5v pins I had 0v

So as a result I obviously have an issue with the 5v rail and the 34v rail, I believe the 5v rail is the one that affects the boot sequence and the 34v is not an issue at the start up, however, it’s there for a reason and this simple test proves there is an issue. I will therefore only change the IC and three transistors as the capacitors were changed when I did a full recap.

Advertised shell
What actually arrived
Clean Amp duo sound
Power board components
Three of the above Photos courtesy of Retrosix

For my modifications I am getting a new clean amp duo audio board with dual speakers instead of the single mono one that is standard. This is an upgrade on the original, extremely efficient and with better sound processing.

I am also replacing the shell with a new Blue case and glass to replace the scuffed old screen, this shell also has dual speaker outlets to compliment the audio board replacement. The shell is already prepped to accept a rechargeable battery system should I decide to install it at a later date.

I shall be getting these upgrades from Retrosix who specialise in supplies and modifications for gaming consoles.

All the items have now arrived and the first thing I’m going to do is sort out the replacement IC and transistors on the power board. The rest is fairly straightforward. However they have sent me the wrong shell, a single speaker one instead of a dual speaker one, so I’ve now got to await a replacement, annoying!

Scratch that, they are saying that they never did have any duo speaker ones even though they were advertising them on their site ( as per picture above..) and after a protracted discussion with the supplier / owner i’ve come to the conclusion that he might think he is a wizard at modding and designing circuitry but is totally and utterly inept at customer service, he wouldn’t know good service if it bit him in the ass. Hey ho on we go, it is what it is.

If you choose to use them in the future then just be aware. They have an uncanny knack of trying to pin their inadequacies and mistakes on you, the customer. Caveat Emptor – as they say.

So now the sound will be original mono, but hopefully improved. I have a spare speaker and mount as a result and I can use the new clean amp duo board in a mono configuration. Should I get a duo speaker shell sometime in the future I can always do a swap out.

Blank shell
New speaker and buttons

Today I’ve taken the empty new shell and installed the new audio card and speaker, as well as the new buttons and silicon pads. I’ve then installed the main board minus the power board that still needs the new components.

New board and old board

Audio and power boards connected

I’ve also installed the new front lens on the unit and I must say it looks nice.

New front lens on unit

Let’s get to the difficult bit, replacing the components on the power board. I’m not joking when saying that some of these items are not much bigger than a grain of rice. I suspect a lot of bad language will be used here, as this is a new level of soldering for me. I’ve never replaced anything so small before. If I balls it up I’ll just have to await my cheap Chinese power board.

Ok, the power board from Ali Express got here really quick, to be honest even before I could set some time aside to change the components on the old board, so therefore I’ve decided to try this new board as a straight swap.

I will keep the the components and the old board to use at a later date.

First though I have used the bench power supply to test it is ok, and it’s a big tick on all voltages as per the test I did on the old board. All voltages are stable and consistent, so I have secured the board in place and put the required batteries inside. Works perfectly.

Back together, awaiting the big switch on
Working perfectly

I now have a perfectly good looking updated Game gear that I am exceptionally pleased with. The sound system is a good upgrade, it has a really loud volume (adjustable) and is crisp. The powerboard from China at a total cost of £10.80 is an absolute bargain, and works perfectly with good stable voltages. The case is good, fits well and the lens is clean easy to install and scratch free, the whole thing looks brand new.

Two old rebuilds, rejuvenated

I now have two perfectly good looking and working examples of 90’s retro rivalry in perfect working condition. The plan is to display these in the house, on a custom made display. I’ve really enjoyed working on this little project and I’m made up with the outcome.

The only things left to be done would be to change the power supplies to rechargeable and to change the screens to new IPS/LCD screens, but I don’t think I’m going to do that on these two, I’m keeping them original or as close as possible to original, I want to keep these as they are, to cherish in this condition for as long as I can.

I love them. And they are fantastic.

Sega game gear 2110-50

What the listing stated:

SEGA GAME GEAR Console FAULTY

Ebay

And that was it. Faulty. What’s faulty? I’ll not know until it arrives as i didn’t ask. Foolish perhaps, but I was looking for a challenge and something I could later mod. I think I’ve found it.

Sega GG front
Sega GG rear

I must admit I was looking for a cheap way into a retro gaming repair and I believe this was it. Most damaged game gear units seem to be averaging around the £42GBP price but I managed to get this 2110-50 version at a lower price of £28GBP (and I may have got a game with it, let’s see what arrives!). However I don’t know what the heck is wrong with it but I suspect it’s the usual issue that has plagued these 90s retro units since their inception where the capacitors fail catastrophically.

There is probably not a single one of these units out there that has not suffered this issue or is certainly guaranteed to do so sometime in the not too distant future. Imagine how many of these units have just been discarded as junk considering that 10.62 Million units were sold up to and including its discontinuation date in April 1997….scary!

The first recommendation from anyone in the know is to change the caps before they start popping and corroding everything. I have a set of replacement caps ready in anticipation.

Full GG Cap replacement
GG Cap replacement list

My hope is that this unit has not yet reached that corrosion stage….fingers crossed 🤞

Hurry along now Mr.Postman….

Both Game gear and replacement Caps have arrived. And I’m really happy as there is a game in the unit as well “Columns” Sega’s answer to Nintendos Tetris. A nice bonus.

Just minor scratches on lens area
Bonus game received…Nice
Nice and clean

The unit turns on, there is no sound, and only a very feint green glow when the unit is held at an angle. It’s looking very much like it is the old Capacitor problem.

No sound. Powers on.
Turns on and green glow

The unit is in surprisingly good order with scuffs and minor scratches as you expect from a game that’s around 30yrs old. The lens scuffs aren’t an issue as a new lens is relatively cheap. But that isn’t the problem as it stands. Let’s get it working and I can worry about that later in the repair process.

Clean battery compartment
Another clean compartment

There are no signs of any corrosion in the battery compartments and this pleases me. I only hope that when the unit is opened there are no obvious signs of corrosion on the boards.

Wish me luck, I’m going in….

Overall I’m happy with the condition inside, no bad corrosion, however it’s noticeable that a few capacitors have leaked. The worst seems to be C39 on the main board, it’s easy to see the residue.

Main board Capacitor C39 leaking

This unit separates into three boards. An audio board, a power board and the main board. This is a twin asic board, I have removed the audio and power boards as these are the first and possibly the easiest for me to be working on.

The audio board has 5 capacitors that require replacing, I can see some leakage on the rear of board but not in the area of the capacitors. I suspect that this is factory flux though I could be wrong. When I remove the caps I’ll clean all the pads and use IPA to clean so this should sort that issue out.

Audio board Leakage or Flux

The power board only has three Capacitors that require changing, however it’s clear to see here that C5 has been leaking.

Powerboard C5 leakage

Let’s get on with the removal and replacement of these 8 components. The other 11 are on the main board.

Well that didn’t go too bad. A few minor position changes due to the capacitor types being a different size on the board compared to the 1990s version.

Old caps and new
Audio board cap replacement
Audio board now clean

It was obvious that there had been leakage on these two boards due to the fishy smell that arose when the soldering iron was used. That said, the old capacitors came off without too much problem. I used solder braid to remove the old solder and then gave a good clean of the board with IPA prior to re tinning the pads prior to putting the caps back in place.

I knew there wasn’t a big issue with the power board as this was sort of working prior to this project. This was the easiest board to solder as it had through the board components, pretty much a straight swap but for better components.

Power board with new caps
Power board clean

The audio board was different as I had to reposition these pots so the case could close properly and the shielding could go back into place with no issues. Again I used the same process of unsoldering, cleaning thoroughly and then tinning the pads.

These two boards are now complete. As a test I thought I’d reassemble the unit and see if there was any improvement. Power came on and the red led lit, this was a good sign that there was power and I’d not messed anything up. Secondly there was sound, we didn’t have that before so this is a definite improvement on what we originally had. Volume works with just a couple of occasional crackles so I may have to use some more contact cleaner here.

We have sound

So far, so good. No real improvement to the picture even though you can see something is trying to come through. That said I’m hoping the replacement of the caps on the main board will help this. So with no further a do, let’s get the main board finished.

Just got home from work, now time to get these last 11 caps done. All the old ones removed, all the pads wicked to remove the old solder and what a stink of old fish, these capacitors had definitely died.

All old caps removed
Old caps removed and area cleaned

All cleaned with some IPA to rid of all the debris and then fluxed and tinned the pads ready for the new capacitors to go into place, I’ve got this off to a tee now and these went on a lot quicker, easier and tidier than the last lot. I’m a lot more competent now, and feel more confident with this process.

New caps going into place
Last two new caps go into place

Had a little trouble getting it all back together, a couple of the new caps had to be tweaked slightly as they were in the way of a screw post, the earth shield was also causing issues and shorting the system, again a bit of captain tape helped shield an exposed component. All this done I put the strap back on and loaded up the batteries. Switched on and red light, all looking good…

All working

Very happy with the fix, that was my first Cap replacement and I’m happy with my first attempt. Again you learn from these attempts and the reluctance I initially experienced was just nerves. I’d be more than happy to do more of these fixes, maybe using the modern surface mount components next time.

Columns
You did it

Another one saved from landfill, I wonder how many of the 10.6 million more that were made of these have suffered that very fate. Scary.

Anyway, I’m looking at using this unit to do some mods, so this is going to be my test bed for other projects.

Simple fix, great outcome, I’m happy.

Big Trak CE3962 restoration

Big Trak CE3962

I refer you to the post I wrote earlier in June 24: Teenage jealousies revisited

Here I purchased the toy I most wanted back in my teenage years. Unfortunately I wasn’t available to get the original MB version produced in 1979 so I had to settle for the latter “improved” version made by Zeon Ltd that was made in 2010.

It’s arrived and to be honest dosen’t look too shabby, needs a bit of a clean up and maybe some new transfers applying but we’ll get to that at another time, for now we need to try and get the machine up and running.

I’ve eventually managed to get the lid off. This unit was built to ensure that it was difficult to get into so repairs couldn’t be carried out. Some of the screws are buried under fascia dressings, and if you aren’t careful you could end up snapping some of the body shell.

With the two halves of the body shell detached it’s obvious there are some detached wires. One was a battery wire, one was a speaker wire. Oh if this was the issue wouldn’t it be great? But it wasn’t. I soldered these wires back into place, put the three D types in place and it was still dead.

I’ve now desoldered all connections from the circuit board to assist in carrying out checks for continuity and tracing voltage. I can also check the board under the microscope. I may change all the capacitors for SMD ones.

I started checking continuity and tracing voltages and was doing really well until I got to a large section of the main board where everything seemed dead and unresponsive. What the heck was going on here? And then I noticed the wire had detached from the positive probe of my multimeter thus ending any further testing for today. I need to order some new probes. Well, I’ve ordered some nice new probes and croc clip connectors as well, so as soon as they arrive I’ll get back on with the testing. They arrived and were damaged on arrival, so back to the drawing board.

I took the drive train to pieces and here it became apparent that a number of the cogs are damaged. I believe there is also some issues with the motion detector but I can’t confirm that until I get some power into the motors. I can’t find spare cogs online so I have ordered myself a second damaged unit to use as salvage. To be honest this new unit has all the transfers in place so I will probably use that shell and the guts of my original unit to form one complete Big Trak.

New donor Big Trak – better than my original one

The donor unit has arrived and boy I’m impressed. It’s in far better condition than my original one, so as expected this one will become the working unit and my original one will be come the donor. Any parts left over will be sold on as spares or even used on another damaged one if I can source it.

My new Bigtrak

If you look at the video above you will see the new Big Trak going through the motions. However the one thing it dosen’t do is turn. Could be a wheel sensor issue who knows. Good thing is that the cogs haven’t broken as the drive wheels are both solid and not free wheeling.

There are only two real issues with the donor here. Firstly it will not do the turn command and secondly, one of the drive wheels is damaged. Luckily I have a spare wheel so this was swapped over, some decals were missing but I coaxed these off my old truck with a hot air gun and reapplied them with no issues.

Looking into the drive issue meant opening the gear box. In here we have two magnetic independent gear controls that should have a gap between them, these two were stuck together thus rendering independent motor operations of the turning control useless.

I removed the two motors and repositioned them and the cogs holding the magnetic gear, this gave a gap of about 3mm that now allows the wheels to turn in opposite directions allowing the unit to turn.

Now the Magnetic sensors are adjusted….it turns

Whilst in this gear box I was able to confirm the issue with my old gear box and it really is all down to two damaged drive cogs that I need to obtain. I’m pleased with that as I could now get two good working units for just a small outlay once I can source some cogs. I will have to repair the wheel I removed to replace the one on my new unit however I have an idea how I’m going to remedy this and again it’s a low cost option. But that’s a job for another day.

2:18 of rebuild magic

So if you look at the video above, it’s the full fix that I posted on YouTube. Really pleased with this fix, again I’ve learned quite a bit about these units and I’m going to have immense fun programming it. My wife dosen’t understand my excitement over this toy, but all my old buddies and colleagues understand it as they grew up in the same era. Maybe it’s the male menopause, reliving the past and all that.

But hey, it keeps me occupied and out of mischief so who should worry about that

This one is going on my shelf so when the kids visit I can show them the joys of basic programming we experienced back in the day.

Job done.
