Onkyo TX-NR717

7.2-channel home theatre receiver, Internet-ready

A bit of a different one here, i get into work one day earlier this week, to be told that one of my colleagues in a different area (Nottingham) will be calling with something to discuss. That call occurred today and the discussion was about his home theatre surround sound system that had packed up on him, and would I be willing to look at it for him to see if I could manage a repair. Though it’s something I don’t usually do repairs on, I said why not? I need to look into other areas of repair and as long as it wasn’t urgent and there was no urgency, then I’d certainly look into it for him. It turns out there is no hurry and he will get the item down to me in the next few days.

So I now have a task, that I am really quite excited about. And for obvious reasons I want to do a good job.

Here’s a little bit about this item

With the power to fill large rooms with THX certified sound, this cutting-edge receiver is ready to integrate and distribute entertainment throughout your home. More than a home cinema processor, the TX-NR717 allows you to access music on PC, stream from MP3 tunes, explore online radio, or connect your iPod/iPhone to one of two USB ports. You can distribute any of these various stereo sources to other rooms for house-wide entertainment. With a total of 10 HDMI connections, this receiver converges HD content from all your components – even your smart phone media via a front side MHL/HDMI – and provides easy input selection with InstaPrevue technology. HDMI also enables intuitive GUI with overlaid quick set-up menu. Video upscaling to 4K, Audyssey DSX seven-channel sound expansion, and Audyssey 2EQ room correction are all included. Sound quality is quite simply the best in class, with powerful WRAT amplifier, three-stage inverted Darlington circuitry, and discrete output stage components delivering an otherworldly entertainment experience.

Onkyo TX-NR717 – AV network receiver – 7.2 channel – black

Release date: April 2012

Onkyo

I’m looking forward to this project, a little out of my comfort zone, but it’s the best way to learn about how these things work. And I need some exposure to these types of systems and the issues that can occur within them.

Assessment:

This unit has just about reached its teenage years, and if this can’t be repaired then the owner will be looking at his alternatives. However replacement units have also grown in both features and price now, so if this current box of tricks can be given an extended lease of life then everyone is a winner, and one less item gets to go to landfill.

I have downloaded both the instruction manual and the service manual, so I am equipped with a full list of components as well as the official schematic diagrams of the circuitry layout. I’m suitably prepared for this one.

The report from my work colleague is that it was working fine up until a week ago when it would just not switch on. He has replaced the two quick blow fuses that he saw when he opened the unit, however the issue still remains. He hears clicking when he turns the system on, this could be an issue in the standby circuit, however I will have to wait to have the unit in my possession to investigate this any further.

Straight to the point…just how I like it

Just got a message from one of my colleagues at work to say the parcel from Nottingham has been collected. Just love the straight to the point way these guys inform me of any safety issues and concerns they may have 😂

And on opening the box, more surprises. Biscuits, they are my downfall, and don’t ask about the Aubergine, we won’t go there, that’s a private joke 🤦‍♂️

Right, serious head on now and I’ve plugged the unit into the mains and without touching anything at all, all I can hear is a metronomic clicking that appears to be emanating from the power board circuit area. This will be my first port of call.

Repair:

There are two well known issues regarding these units and I am going to look at both of these before getting in any deeper. The first issue is around the relay and its associated 150 Ohm resistor on the main power board, the second issue is around a defective capacitor on the standby board, and eliminating one issue will either highlight, or clear the other. If both issues are addressed with no change to operation, I will have to look in to the issue a little deeper.

Issue one relates to a problem with the relay on the main power board. Most people don’t realise this but pressing the power button on an Onkyo receiver does NOT turn off the power. The power button merely sends a signal to the MAIN CPU telling it to close a relay (to turn the system on) or open a relay (to turn it off). When you press the power button on an Onkyo and nothing happens (no clicks, no brief lighting up of the front panel) the root cause is often a blown coil in the main power relay.

Main relay is the item under the thick coating of white silicone at the top of the picture

Beside the relay to the left is a resistor that should be reading 150 Ohms. This particular one is reading 144 Ohms so is reading a bit lower than expected. This could be sufficiently low enough to allow the relay to fail. So at this point this looks like a possible point of failure. Either way they need to be replaced before we can advance any further.

Silicone removed. The faulty resistor is within the red circle

I need to obtain these parts, the relay will need to be shipped from China, and I need to check my resistor stock to see if I have a suitable replacement resistor. The relay also should have a similar resistance to the resistor beside it, the healthy range for the relay is between 80-200 Ohms.

I have removed both components from the board to test them out of circuit.

The resistor beside the 9v relay is a 150 Ohm rated resistor. This one reads at 144 Ohms and is to the lower end of the rating of +/- 5%, it would probably suffice, but i’m going to replace this one just in case. The only other resistor in this circuit is a 47 Ohm resistor and that reads exactly as it is rated, so there is no issue there. I believe the bone of contention here is that the relay is 9v sitting upon a 12v power rail. This is probably the reason issues have occurred with these units in the past, and looking at a number of forum posts, it is quite acceptable, even recommended to use the higher voltage 12V versions. I’m sticking to the original design on this repair though, I can only presume the 150 Ohm resistor placed just before the relay has something to contribute in controlling the operation of this relay. Maybe that’s a design fault within this model, I just don’t know!

I have tested the relay using a multimeter and a 9v battery. I have used the battery to short across the power poles where I can hear the relay clicking, but when the relay is on there is no continuity across the other two pins when there should be, this isn’t happening so I suspect this relay is stuck in the open position. The Ohms rating across the pins shows 336 Ohms, so i am lead to believe this could be a problem with the coil inside it, as it shouldn’t really be that high. I understand from what I have read, that a rating between 80-200 Ohms is classed as acceptable, and outside this range could indicate that there is an issue. I’ll just have to wait until the new relay arrives and carry out some tests to see the comparison between the old and the new relays.

I’ve dismantled the cover from the relay to get a look at the coil. In the little video below you will see the coil switching, however you will also see the contacts meeting but there is no continuity. The contacts have a coating of contamination on them probably from age or arcing, it looks like a carbon deposit, as when they adjoin there is no contact made, no flow or continuity, unless you put light pressure on the contact and then you get the continuity. It is at fault, it shouldn’t be doing this. A clean of the contacts might breathe some life into it, however give it a couple of months and you’d probably have to remove it again, and the contamination isn’t the only issue, don’t forget the relay reading that appears too high. A new relay costs less than £4:50GBP delivered from the other side of the world, so I might just as well go for a new relay. It makes sense.

Inside that failed relay

I’m not going to venture any deeper into this unit yet, not until these components arrive and I can get them back into place. I want to move through this fix confidently and slowly, have a better understanding of what is going on and not leave myself confused with bits and pieces everywhere, clueless to what is occurring. I wouldn’t achieve anything by working like that. Knowledge is king here and I’m here to learn. And I do now have the schematics available to follow.

I’ll have to wait about 2 weeks for the relay to arrive so I’ll just have to put this repair to one side and on hold until then.

Ok the new relay has arrived and the first test I did on it was to take an Ohms reading of the coil side. Now if you have paid attention, you will have seen that the old relay was reading 336 Ohms when it should be somewhere between 80-200 ohms. This new relay is reading 158 Ohms and I feel a lot better about that, it falls right in between the expected spec.

Old relay reading on the left versus new relay on the right

And if you want to see the relay actually working and displaying continuity then have a browse at this video below, the polar opposite to the first video I posted above 👆

The new relay with good continuity

The resistors I ordered have now come through and have been tested, I have a couple of candidates displaying better test results, so we can now look at getting these two components back in place to see what occurs.

I’ve put in place a new resistor, slightly higher value than the previous one coming in at 147.4 Ohms. It falls within the 5% tolerance so should be fine.

The relay has been soldered back in place, really simple just four points to solder and we can now reassemble the power board back into the chassis.

I’ve taken the unit into the garden at my wife’s request, as I have to use some high pressure air to give it a good blast to get rid of some dust and furballs. This has worked well and quite a dust cloud was witnessed across the garden, it’s fair to say it’s a lot cleaner inside than it was.

I’ve now put the case back on and the unit is now sealed from prying eyes and inquisitive fingers. I’ve given the entire case a good polish and I must admit it is looking nice and shiny and very presentable. I just have to hope and pray that it turns on. I see no reason as to why it shouldn’t but you just never know. You can always fix one problem only to be chasing it around the system as it develops into another fault, repairs can sometimes go like that.

Let’s plug it in and see what happens 🤞

Result:

I’ve plugged it in and turned the power on. No bang, only silence, just a single click when the power went on, this is good. When the power is turned off you hear the standby relay do the same, all is as it should be.

The standby relay has clicked in when turned on at the power socket, and is not repeating that metronomic sound that was there originally. Superb. Now to turn the power button on, on the front panel.

We have a display. Excellent it is working.

All buttons are operational, I don’t have the surround sound speakers as they are at the owners house in Nottingham, i also don’t have the remote here that also allows me to do other tasks, however that is not important as the unit is now operational and displaying what it should, and once it goes back into his media wall with all his speakers and other related sound and Av equipment, i am confident beyond doubt that it will be operating just as it did prior to this issue developing.

I will be handing it back with the advice that should the issue occur again we look at updating the relays with new 12v versions to replace the current 9v ones. But I doubt the problem will re occur, and this repair should see out the next few years at least and by then this unit will probably be sold, or passed on to someone else when he decides to upgrade his system.

Below is the little video I sent my colleague showing him the unit now working

It’s now working

But for now, it works. I am pleased as punch with this repair as I have stepped out of my normal comfort zone here. I have been extra vigilant, studied many a schematic diagram and learned a lot from this project. I didn’t rush ahead of myself and took this repair one little bit at a time, testing all along the way and addressing each issue in the order that it has arisen. And I’m damned happy with that.

It’s been a learning project for me, and I’m glad I’ve undertaken it. Life is for learning, and I’m living that life.

Many thanks for passing by, as you well know it is always very much appreciated.

Edit:

Today the 29th July I have had a message back from my colleague to say that he now has the unit back in his media wall. And I’m pleased to say it’s working perfectly. He’s very pleased and so am I.

He’s pestering me to bill him, but I’ve told him that I’m only taking one currency and that’s not money or crypto. No, my method of payment will be in Biscuits. I told you I’m a Cookie Monster and this entire repair only cost just £4:17GBP. That’s not a lot of Cookies, but it’s credit in the bank if these guys need any further repairs carrying out. Word of mouth, works wonders.

Comes with front / rear lens caps

EBay

Anyone that has followed my recent repair of the camera: Fujifilm Finepix S2 Pro will be aware that I purchased a lens as a test lens for working on some stock that required a Nikon mount. I went cheap and purchased a lens that was so badly affected with lens fungus that it will require a deep clean and some TLC. Anyway, it allowed me to test electrical contacts and all the menus, and that was about it, it served a purpose there, but taking a picture was like looking into a deep fog, it was hopeless. Anyway that lens is now set aside and will become one of those projects to dig into on a long winter evening…or two, or three.

As I have a number of Nikon based cameras needing assessment on the horizon, some with sensor issues, i have made the decision to pay a little more for some quality, from a company called AP photographic who specialise in quality used equipment, a company that is based close to where i used to live down in the south. This Lens has cost me £58:95GBP including postage, a fair but good price for some peace of mind. This post will not be a repair post as there is nothing wrong with this lens, it will be more of an assessment of the lens when used with the Fuji S2 pro i featured in a previous post.

Nikon Nikkor 28-100mm Zoom Auto Focus Lens F3.5-5.6

I’ve put this post up to show the difference in the pictures taken on the S2 with both the old lens as well as this lens. I think the results will show quite a noticeable contrast and confirm just how restrictive a lens is when it is infected with a fungus problem.

Assessment:

The lens arrived within a couple of days and is in perfect condition. It has a lens cap and bayonet cap so is perfectly protected against dust dirt and damage from foreign objects. And when the lens cover is removed there is another little surprise, a post it note saying “Filter is a free gift” that just happens to be attached to a daylight filter. Nice little touch 👌

Lens is a perfect fit, no aperture ring on it as it is fully automatic, full autofocus. I’m not sure how the flash will work with this lens though when I use the Fuji S2 Pro, as that body works best with a fully closed lens aperture, but I’m sure I’ll be able to work it all out and get it functioning as it should. And I did, i played with the Aperture settings in “A” mode and it works just fine. It’s faultless.

That said on the S2 it not only looks good, it takes good pictures. Compared to the lens I last used this one is crystal clear, not a bit of fungus no aberrations and not a speck of dirt. This is a good lens and will serve me well for the purpose of testing other equipment I have awaiting attention. I think I’ve purchased a good example here.

Result:

I can confirm that the Fuji S2 Pro does not have a thing wrong with it and is working perfectly. All modes, all conditions are performed just as they should be. This lens is gorgeous as it is so clear and has been so well looked after. I believe this whole unit will be the one I wander about with when i go out on my walks. I can’t wait to take some serious photos to post.

A quick comparison fungus lens v clear lens as seen on the camera LCD screen

I took some pictures just randomly around the home setting with the old lens to show how foggy things were with the lens fungus. I have tried to take some more photos of the same locations with the new lens as well to just show how they compare and these can be seen in the pictures grouped below.

Before and after pictures, what a difference the fungus has had on the results.

All these pictures are on an old CF card so it is a bit of a palaver to get them on to new technology, but it is doable, it just takes a little time, and this gadget allows me to load numerous card types even the CF cards direct to my iPhone via a lightning connector. It also has a USB-C connector for other phones. It works really well as you can see in all the pictures in this post.

Multiple media cards direct to my iPhone

And below are a few random photos taken on the S2, it has a good black and white mode but is quite heavy on contrast. Post editing would probably be recommended, but to be honest I really love its moody appearance.

4 random photos in and around the house. And Tabs the feral cat popped by

This camera and this lens have proved fantastic. I know you can get far superior picture sizes and quality on a basic mobile phone, but where the heck is the fun in that? This camera cost me £8:00GBP. Just £8:00. And it is a superb camera that will be going on many trips with me as I just love it and how it looks. I now know it intimately after reading up on it and testing it, and cannot wait to put that knowledge to use.

Cameras are better than mobile phones. Old ones like this are fun, and an absolute privilege to use. It’s not all about the Megapixels, just remember these old cameras were the ones taking high quality professional pictures back in their day. Just because time moves on, and just like an elderly old lady or gentleman, they should not be discarded because they no longer serve a purpose. Respect the older technology, learn from it and you will ultimately become a wiser person yourself. Oldies rule! Never forget it. 👊

Thank you so much for passing by. It’s always very much appreciated.

Fujifilm Finepix S8000fd

What the listing stated:

ALL ITEMS IN THIS LISTING ARE FAULTY
FAULTS MAY VARY BETWEENS ITEMS

SOLD AS IS

NO RETURNS

EBay

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 really don’t know what the specific issues are with this camera, only that it appears to have the mode selector dial missing from its top. I guess we will just have to wait it’s arrival for a full assessment. In the meantime here is a little bit about it.

With the release of the FinePix S8000fd, Fujifilm brings to market a smart-looking digicam with an 8-megapixel imager, one of the longest zoom lenses in the market plus a compact, and relatively light, camera body. The cheapest of three similarly featured long zoom cameras in the current market (see table below for a feature comparison), the S8000fd has the distinction of being able to use both xD-Picture Card and SD cards (including SHDC), which are fitted in a single dual-format slot. Release date July 2007.

Photo review newsletter

Assessment:

Well, to be honest, for potentially the worst camera in the box of the three that were purchased, it works just fine. Apart from that missing mode selector dial on the top of the camera. You have to use a pair of tweezers to get each mode to appear, but they are all there and the zoom and flash all work and it takes pictures fine, just as it should.

Apart from the issue with the dial, all that is really needed is a little clean up, and even that isn’t that bad.

It does not justify being used as spares and is far too good to just be disposed of. I’m going to try and repair this.

A little bonus was that there was a 1Gb SD card in the memory slot that works. There were also 4 rechargeable batteries in the camera that after a while on my charger, have fully recharged, and this makes the deal an even better one and quite a bargain to be honest with you.

Repair:

I’ve tested all systems, menus and functions on this camera and there really is nothing else wrong with it. It’s far too good to be used as a spares camera and deserves to be repaired.

I have two options here, either buy the mode selector dial on its own from our friends in China, or buy another donor camera in a far worse state and available for about the same price as getting the dial from China. I just have to wait for that donor camera to first become available. I’ll give it a couple of weeks and if nothing comes up then China it is.

In preparation for whatever route I decide to take, I’ve decided to do some prep on the old camera and get the old selector dial mechanism taken out ready for the new dial to be put in place.

I’ve dismantled the camera unit to be able to access what is left of the mode dial switch.

This wasn’t too awkward to dismantle, half a dozen screws and a small plastic prise tool was all that was required to reach this point. There was some protectorate covering the metal frame of the switch housing that was contained by four tiny screws. Once this was loosened the housing came away and I was able to remove what was left of the old mode dial that had originally been in place. There wasn’t a lot left.

The camera now sits in this position of being dismantled whilst I source a new dial to replace. As stated I have two options of buying a new dial either from China, or by getting a damaged camera as a spares source, and I’m currently looking at the latter as this could be purchased for about the same price as the dial from China, and would allow me a few more spares.

I’ve purchased another unit as a donor. The unit in question has a damaged LCD screen. I’m going to use that camera as a donor for the mode dial I require.

The donor camera has arrived. And to be honest it looks ok. It has been dropped at some time as the lens has a scratch on it, and the Rear LCD screen is damaged. That’s about it.

A good looking donor camera, the only issue being the damaged LCD screen

I’ve taken some pictures with this unit and the camera is working fine, as you can still view pictures you have taken through the viewfinder. It works ok, but I need this mode switch to fix another camera, so i’ll probably just use what remains as spare parts due to that scratch on the lens.

Let’s get the donor camera disassembled to harvest that mode switch.

There are only about six screws to get the back of the camera taken from the body, you just have to be careful not to damage the ribbon cable that is connected to the mode dial assembly that we are going to use today.

The two cameras, and the mode dial assembly we need to fix the original camera

I did all the disassembly of the original camera to save time, and it took about 5 minutes to get the donor camera stripped down. Once inside there is some insulating material covering the switch assembly, this has to be removed but cannot be reused as it has lost its adhesion. When reassembled I have used electrical Kapton tape to replace the original insulation. This has worked just fine.

Assembly involves checking that the button settings relate to the markings on the camera body, this is important at this stage as the last thing you want to do is reassemble the camera to find out that you have the dial in the wrong setup. Do it now and save time and reduce the possibility of damaging the connectors and body clips.

Result:

We have a beautifully restored and working and fully functional bridge camera that takes good snapshot photos. It’s not high end, it’s very much a learner camera but good at documenting what’s going on around you. Its mode dial that was missing is now working fine. A little polish and it has come up looking lovely cosmetically. it’s a good little unit.

The camera has come up lovely and is now complete and fully operational

Here are a selection of snapshots from around the home just to prove it’s working as it should. Nothing special, it just does what it was always built to do. Take snap shots.

It works. I’m happy. And another camera has been saved from landfill.

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

Panasonic Walkman cassette player RQ-P250

At a family gathering this weekend, an elderly family member approached me and asked if I could take a look at his Panasonic personal tape player, and maybe get it back up and working.

Who am I, to turn down such an invitation, so I took it on and promised him I’d have a look into it. There is, “No rush“ I was told. Just as well, as it’s busy in every aspect of my life at the moment.

Here’s the spec:

Type: Auto Reverse Cassette Player

Tape Type: type I, CrO2, Metal

Output: 20mW

Battery: 2 x AA

Power Supply: RP-AC33 (3V DC)

Dimensions: 114.2 x 84.4 x 33.1mm

Weight: 156g

Finish: black

Year: 1993

Hifiengine

Assessment:

It’s well used, and has always been and if I can get it working, will continue to be so. At the grand old age of 79 my brother in law is not about to change his ways and is quite comfortable listening to his old Cassette collection whilst out and about, on trains quite a bit of the time, as he travels up and down the country. He’s a lovely old fashioned set in his ways guy and we wouldn’t have him any other way. It would be blooming lovely to get this back to him working again.

It’s scarred, been well used but looked after, apparently it’s gone from playing quite well, to slowing down and dying completely. I think I know what the issue is but I’m not going to curse myself by saying I know what is wrong, when it actually turns out to be something totally different.

And I love his choice of music. Let’s get this repair underway so we can listen to Mr. Rea in a lovely crisp sounding manner befitting of an 80s rock star.

Repair:

Batteries in place, earphones connected, push play. No movement from the capstans, and even when put in forward and reverse there is no movement from either capstan. I can hear all the electrical noises such as the tape head picking, and I suspect at the grand old age of 32 years old that the drive belts have probably given in. Let’s open it up and have a look.

And just as I thought. Two drive belts in here, they are both loose, one though is so loose that it has wrapped itself around the two capstans, no wonder it wouldn’t start up.

Two drive belts visible, both so stretched that they have ceased working

I have plenty of these belts spare, I just had to sort out the two closest matching in size. Too slack and you introduce warble, too tight and it will be off speed, you need to get it just right. Adjustments can be made to the motor speed but this will only come back to bite you once the belts wear in.

I’ve put two new belts in place, and at some frequencies there is a little wobble, but with Dolby switched in place this can be removed digitally, this will settle over the coming weeks after more use.

I have used some silicon grease on the cogs, I have put contact spray in the motor and the volume controls, and used IPA to clean all the tape contacts and capstan wheels and posts, it’s basically been given a little service to see it forward for a while longer.

Body now reassembled, new batteries put in place, it’s time to test it.

Result:

A quick polish, to tidy up, won’t get rid of the deep scuffs, just makes it a little more presentable. Cassette inserted, headphones plugged in and as expected it’s working just fine, we can hear Mr.Rea in all his gravel voiced glory. So can you, in this video snippet below, that hopefully won’t get a copyright strike 🤞

🎶 On the beach 🎵

So there we have it. Another item brought back to life with about 30 minutes work. It’s going to make someone’s day, and I’m as pleased as punch that I could play a part in contributing to that.

Working well, looking ok after a quick service and some TLC

There you go. Hope you enjoyed this quick fix.

Many thanks for passing by. Always most appreciated.

Sinclair Cambridge Memory Calculator

What the listing stated:

This auction is for a used cased Sinclair Cambridge Memory pocket calculator and original case. The item is in very good cosmetic condition as is the case which still has its instruction sheet. The item is powered with 4 x AAA batteries (not supplied) and does work although 1 of the digits is faulty and does not display (see pictures) plus the number 5 digit is not working. Please refer to the pictures and description provided before bidding.

EBay

So it does work, but it doesn’t? This calculator is a model one memory calculator, that dates from around July 1973, ( Actually May 1975 see photos below) and is one of the earliest available mass produced electronic calculators available in the UK at the time. And it was produced in collaboration with a guy called (Sir) Clive Sinclair, who in the following decade would become synonymous with tech development in the UK. It retailed at £29:95GBP, and given the rate of inflation, its cost today in 2025 would be a staggering £463GBP. Wow!

I love collecting old calculators, I couldn’t afford one back in the day when they arrived on the scene as I was only a child and probably only on about 20 pence a week pocket money, and savings and investments were not even known to me at this period of my life. The thought of saving that precious 20p a week for the next 150 weeks wouldn’t have even remotely crossed my mind. What no sweeties?

But I can buy them now, so no big issue!

So this one has become available, and I’ve been tracking it for a week or so, there were nine other people watching but I secured it for a total including postage of £14:49GBP, and I’m happy with that, it’s a piece of retro history for a very good price. Even if it remains faulty, or should I say working but not working?

This unit obviously has its problems, the button number 5 doesn’t work and one of the led digits is also not functioning. Hopefully I can get these issues sorted and soon have the calculator back up and working as it should. That would be nice. I’m looking forward to this little project.

Assessment:

It’s arrived and it’s a lot smaller than I anticipated. It has a separate hard protective case, which is a nice touch and a small info sheet on its operation. Cosmetically it’s in a good condition with just minor signs that are age related. There are no gouges or scars so it has been treated well, though it’s not pristine.

Batteries go in ok but, I believe old style AAA batteries were a little wider than those used today and would sit a bit more snuggly in the battery compartment. As you can see there is a little wriggle room here, and springs at both ends need adjusting to help prevent this. I may have to use some spacers so the batteries sit tighter in place.

The switch is a bit temperamental and can be seen quite plainly from the battery compartment. It looks strangely out of place with no batteries in place.

It is such a basic design solely relying on tension of a small metal plate to short across the connection points. Should be a simple enough issue to sort.

There is a little battery contamination on one of the battery contacts, again this shouldn’t be too much of an issue and should clean up ok with some IPA.

It was originally reported that there was one unresponsive button this being the number “5”, there is also another unresponsive button, the multiplication “X” button. There is also one LED indicator, the 4th one in from the left hand side that is not operating. Add to this the issue with the On/Off switch and the contamination, and the original faults reported in the original sales pitch have now doubled. I just wish people would spend more time going over the issues and then give actual accurate feedback as to what the real faults are, it would make for a far more pleasant buying experience. Rant over.

There doesn’t seem to be a single screw holding the body together, I just hope it isn’t all heat welded.

Let’s try to get inside.

Repair:

Well it cracked open quite nicely with no issues with just a plastic flat prise tool. The main board just sat comfortably in the unit, secure, and not a screw in sight. Strange as time moves on some of the games units I come across have best part of fifty of the little blighters to remove before you get anywhere. sometimes the old way is good.

The dismantling of the keyboard is a little complex and you have to take time and make sure you know how it’s going to go back together, it’s just a bit fiddly. The board is quite straightforward and as soon as I see some of the IC’s it dates the unit perfectly. The chips are dated May 1975, and that is about 18 months younger than what I originally thought, it’s quite informative to get inside and learn occasionally and this is just as good as having a birth certificate presented to you. All good stuff.

I’ve proved that there isn’t a problem with the missing digit on the display as using my multimeter in diode mode I am able to prove that this LED is working fine.

The picture shows just one part of the display range on this particular digit, I can assure you all other sections of the display are also working.

Regarding the case with the buttons not working. I have checked this out for continuity and both digits go through the same portion of the main IC and there doesn’t appear to be any broken traces. It’s a strange one but I have also found some really poor solder joints that are either cold joints or just poorly soldered from the start, there are a couple of resistors that need re soldering. It may be nothing at all, but it needs attention, a full reflow wouldn’t go amiss or take too much time.

I’ve reflowed the entire board due to there being a few cold solder joints.

On top of this I have taken off two old capacitors and tested them out of circuit, and both were out of their operable range of +/- 10%. As a result of this I have replaced the offending components with comparable new ones.

Even with all these extra tasks being undertaken there is absolutely no change in the way it operates. Nothing has gotten worse, the faults that were originally there still remain. I have done some research on line and carried out some further tests and checked expected voltages, most are within range except one that appears to be less than its expected value. After testing everything on this board, every component I can only surmise that one of the three chips has failed, I suspect very much that this, the main chip, a CZL550 integrated circuit. Otherwise known as “Calculator on a chip” is the one that is at fault.

To be quite honest these chips are fairly rare and command a price far in excess of what I paid for the original unit, and I don’t really want to do that. I think I’ll wait around to see if I can secure another faulty unit to complete this repair, so in the meantime, and until I can secure such a unit I will put this repair on hold.

Result:

Well, it’s not what I wanted but sometimes you just can’t win with some of these old projects. In no way am I walking away from it, it’s just that the parts are so difficult to get hold of that you really do have to just wait until a sufficiently faulty one comes up for sale. And that could be days, it could be weeks or months. So for now i admit defeat, but it will not be going to trash. It will remain in my ever expanding “To do” box, for me to pick up on at a later date. And when I am in a position to move this project on, I’ll pick it up in a continuation of this post.

Many thanks for passing by. It’s always appreciated.

Fujifilm Finepix S9500

What the listing stated:

ALL ITEMS IN THIS LISTING ARE FAULTY
FAULTS MAY VARY BETWEENS ITEMS

SOLD AS IS

NO RETURNS

EBay

I really don’t know what the specific issue is with this camera only that it is faulty. I guess we will just have to wait it’s arrival for a full assessment. In the meantime here is a little bit about it.

Fujifilm FinePix S9500 or FinePix S9000 is a bridge digital camera released by Fujifilm in 2005 and intended for the enthusiastic amateur. It is a member of the Fujifilm FinePix family and has been superseded by the Fujifilm FinePix S100fs. It has a long list of advanced prosumer features, like combining having wide-angle ability (28 mm equivalent on a 35 mm camera), full range of manual settings, mechanical zoom ring, high ISO-sensitivities, and some of the versatile features of Live-Preview Digital cameras (LPDs) like movie mode, movable LCD panel, and macro mode.

Wikipedia

Assessment:

Wow. Another camera in a fantastic condition as part of this damaged package of three. And I owned one of these when they first came out in 2005.

I really had to look hard to find the issue with this camera, I have checked every menu, mode and function and it is working absolutely perfectly. Then I found the issue when removing the battery.

Loose battery contact under battery door

Unbelievable, the only issue with this camera is a loose battery contact plate under the battery door. These are normally sealed with moulded plastic, but it looks as if this one has come adrift. It just needs fixing back in place, I can’t believe this is all that is wrong with this camera. Apart from needing a little clean.

And an added bonus with this camera was that it came with a 2Gb CF card. This just so happens to be the biggest drive size these cameras take. You can also use TF cards. Again, this was a very welcome bonus.

Repair:

Probably the simplest of repairs you’ll probably see. I really apologise for this being a bit of an anticlimax to anyone wanting to see a technical repair, because you won’t be seeing one. But just sit and think it over for a moment, that someone was prepared to dispose of this perfectly working camera as it was not working in their eyes. We really are a throwaway society. And then there are simple people like me who love these items. And we fix them.

All it took was a hot soldering iron and a pair of tweezers. The metal plate was held down and what remained of the broken plastic welds protruded above the plate. Using the hot iron the welds were melted back to secure the plate in place as it had been when it left the factory. There you go. Job done. Simple.

Result:

For £8:00 I have brought myself a little bargain here. Ok it’s 20 years old now, works perfectly and does what it was built for. Capturing history, your personal history, both good and bad and creating moments for you to treasure forever.

It doesn’t matter what the megapixels are or any of that chuff the “purists” insist you must have in a camera, just push the button and treasure the output for the rest of your days. These cameras are the ones we should be carrying for fun, to learn about photography, the cameras the kids should have now that we had 20 years back, they still have that life in them and the ability to teach and encourage a younger generation to get into photography. And before you say they have phones, that’s not the same. They’ll learn more from one of these on a phone free afternoon, then they ever will by being interrupted by “Soshul Meeja” all day.

Get out there, get your kids recording their world. They’ll thank you one day.

And yes it works well, the Camera is in cracking order and only missing a strap and maybe a lens cap that I may procure later down the line.

The good thing is that it has been saved from disposal, and has years of good honest life left in it.

Thanks for passing by, you know it’s always appreciated.

Bush handheld radio

Here’s what the posting stated:

Grading: FAULTY (USB SOCKET)

EBay

Simple as that. And yes it’s a tiny radio but in excellent condition cosmetically.

On inspection it’s obvious that the micro USB port is damaged and will need replacing.

I’ve ordered some replacements USB ports from our friends in China so I’ll have to wait a few weeks before I can progress this project any further.

The ports have arrived from China, so let’s look to see if we can repair this unit.

*This project has been on the back burner since May 2024. 13 months later and I’m now on it*

Hello all, time to clear that backlog and what better place to start than here. I do in fact have two of these with the same problem so this is a two for the price of one project.

This should be a simple case of replacing the faulty charging ports that are both micro usb ports. They are small believe me.

There has to be some preparation before we can get the new port on. Using a soldering iron and flux and a little solder wick, I clean the old board remove the old solder and give a good clean with IPA. I then prime the small connections on the rear of the charge port with a little solder. Now I put the port to the board and tack on the earth points. Then using a rework hot air gun I blast the port at about 350 degrees Celsius and hold the port in place with some tweezers until I see the solder glisten and melt around the port. I take the heat off and let the solder set before moving the tweezers and when it’s cooled a bit I check that it’s setting straight, all connections are good and solid. I then just add a tiny bit more solder to the anchor points for strength.

Whilst this is cooling down I check the status of the battery. It is a 3.7v rated battery and is currently holding a charge of 2.8v. It’s a little low but far from being dead. The second battery shows a similar charge.

After the solder work has cooled I use my battery pack connected to a small ammeter to see if the radio and more importantly the battery is demanding any power.

Well that’s good news, 5v in and the demand from the battery is 0.96 of an amp. The battery is charging. And the fix is as simple as that.

A little bit of soldering aerial contacts and a couple of other wires back into place and the whole unit clicks back together. Two screws inserted in the rear and time to switch on. Both radios tune in perfectly and the sound is surprisingly good for these little units. I’m keeping one in my work space at home, as I love having some music around me, I’d sooner listen to the radio any day as I hardly watch TV. The other radio will go into my work locker for when I’m working nights or in the workshop.

In my work space, but it won’t be staying here…

Im very happy with this little project, it only took about an hour and I don’t know why I left it so long. Another couple of items saved from the tip, it amazes me that these units probably all suffered with the same problem of inferior parts that failed early on in the radios existence. Kind of scares me just how many did go to landfill.

Well at least these two are going to carry on for a few more years yet. And that’s a positive in my eyes.

Thanks for passing by. 👍

Fujifilm Instax 100 instant film camera

What the listing stated:

Fujifilm Instax 100 Instant Film Camera – Faulty Untested See Lens Shutter

Otherwise clean,

battery compartment is clean,

unable to test so selling for spares or repair considering the lens shutter

EBay

I’m a tad annoyed at myself here as I had arranged a good price with the seller but because I was too eager I pushed the wrong button and purchased at the original advertised price. The seller must think I am a right plum, and I’d be inclined to agree with him. That said I’ve secured this for a good all in price, and it will be a nice addition to my collection. It’s a 26 year old camera, and i’ve been looking for one of these particular cameras that use the wider format of Instax film for quite a while, but even the damaged ones command hefty prices. I’ve paid an all in price of £28:55GBP here when I should have paid £23:55GBP. Never mind, lesson learned and don’t be so hasty in the future. They can command a good price as can be seen in the photo below:

Here’s some info about this camera:

The Fujifilm Instax 100 was released on May 1st, 1999. It has been replaced by the newer Instax 200, which is very similar except the flash is on one side rather than directly above the lens.

Weight: 650 gr (without batteries, strap and film pack).

Camera-wiki.org

Now this one is being sold with what looks like only one fault that the seller is concerned with and that being a shutter problem. From experience and as can be seen in this recent post of mine: Another Fujifilm Instax mini 8 I know that this is not a “Lens” issue it is in fact an issue with the iris that protects the lens, and is probably as a result of a small spring being disturbed in that area. It’s quite a simple fix and if it is the only fault then that would be quite some result. However, this is EBay that we are talking about and there could be a number of further faults we haven’t been informed of. Now I will just have to be patient until it arrives, there is no other choice.

Assessment:

It’s a big one. Compared to the other Instax mini cameras this one is very big. It’s probably 1.5 times bigger than your standard SLR. It’s big. And weighty!

It’s clean…ish. And there seems to be a strip of plastic, a gate as such missing from the top of the camera near the exit slot. This wasn’t mentioned and I’m quite annoyed about that. When batteries are put inside it makes all the noises, but the action isn’t smooth in the lens extension range. This probably ties in with the advertised issue of the lens iris operation. I’m thinking I paid well over the odds for this particular camera, I’ve been conned here, lesson learned.

There could well be multiple problems here, and if that missing piece on the top is anything to do with light proofing, then we could have an issue. Anyway we will cross that bridge when we come to it. Initially I’m going to stick with the original fault, so let’s attack that and worry about any other issues if and when they crop up.

Repair:

The more I get into this camera the more I find wrong with it. The main issue of the faulty lens iris is a fiddly one. You prise off the last section of the lens turret and the iris mechanism comes away fairly easy.

But then three tiny springs just fall out and this is why the iris didn’t work. Trying to get them in place is a puzzle itself, as no sooner do you have one connected then another drops off. It’s a fine balancing act to get them all back into place. When they are all reconnected it’s a very delicate operation to get them back into place. And even then you have to go to the inside of the camera to ensure that the lever inside that operates the iris, is aligned to the iris mechanism that is being installed back in the lens turret. It’s a fiddly time consuming job.

Iris now working

At this point the rear fascia and associated ribbon cable need to be removed to facilitate this repair. That’s when a piece of broken plastic falls out, it just so happens that one of the posts putting tension on the print rollers has broken. Great. Another problem. I’ve quickly fixed this by using some wire to act as a retention point. Bodge? Yes, but there really is nothing else that can be done here as the plastic case is thin and brittle. I have used some silicone grease to lubricate the cogs and the whole movement is now a lot smoother. It Will work. of that I am confident.

Result:

Well it works but it remains one of my most disappointing fixes due to the dishonesty of the seller. I know, if you buy off auctions it’s Caveat Emptor as they say, I preach it enough but this time I was caught off guard. Lesson learned. But I remain disappointed. Multiple faults, sold as just the one when in fact it also had bits missing that were not declared, very misleading in my opinion. Maybe in future I need to look deeply into these purchases before I give any feedback, i need to change my operation as I was truly shafted here.

It does everything that it should, the motor and transport system work, the iris now works, shutter is good, and flash operates. I’m confident that the camera is working fine but I haven’t tried any film through it yet as it uses a bigger format film and is quite expensive, and I’m not forking out for any just yet. Maybe when I get another wider format model to look at I will pay out. Just not yet though. When I do get some film through it I will amend this post accordingly.

I’m off to calm down a bit now, thanks for passing by, I really do appreciate it. Have a great day.

Fujifilm Instax Mini 40 instant camera

What the listing stated:

Fujifilm Fuji instax mini 40 instant camera . Functional, but flash NOT working .

LISTED REPAIR OR SPARES . NO RETURN .

THE CAMERA IS TESTED AND WILL,POWER UP AND TAKE A SHOT AND EJECT A SLIDE CORRECTLY. Please watch uploaded video .

HOWEVER THE CAMERAS FLASH IS NOT WORKING . This is the reason I have listed the cameras as repairs or spares.

Hopefully someone knows about these cameras and knows whether the flash unit just needs replacing or if it is an electronic fault that needs sorting out can fix it . Otherwise the parts will be useful to someone who repairs these .

No batteries or film is included .

The camera body is in very good cosmetic condition. There are only light surface marks in terms of signs of use . . Please see images as they are part of the description.

The red light to show the camera has powered up lites up when the button is pressed to extend the lens and turns the camera on .

When you close the lens down it locks securely into place .

The frame counter is working .

The film compartment is clean and the rear door shut correctly and securely.

Battery compartment is clean and the battery cover locked into place securely.

The camera is powered by to easily available AA batteries ( not included) .

EBay

Now that’s what I call a great descriptive sales pitch. And that’s because the guy is a professional seller of photographic equipment. I’ve seen the video he posted and all the above is true, it really is just a problem around the flash. Maybe it’s an easy fix? I suspect not but either way it will be an interesting project.

Here’s a little info on this camera:

Hitting the market in April 2021, the Fujifilm Instax Mini 40 takes the updates the Fujifilm Instax Mini 11 introduced but wraps them up in a cooler, more retro-styled instant camera body. Instant film fans will probably love it and with its improved design, there’s a chance that those who aren’t instantly drawn to this form of photography may just want to have a play around with the Fujifilm Instax Mini 40, too. It does cost more than the Fujifilm Instax Mini 11, though, so you’ll have to decide if the cooler design is worth an extra £20.

+ Pros

It’s fun

Great party camera

Easy to use

Looks cool

– Cons

Film is expensive

Viewfinder could be better

I first of all went in with a cheeky bid of £15:00GBP that the seller originally turned down, so I then put in a high bid of £18:00 and as no one else was wanting it, it actually sold for £16:00, just £1:00 more than I’d originally offered. All in all the cost with the postage was £19:45GBP and I’m really pleased with this. Im surprised though that there are flash issues in a unit that is only just four years old. As you can see in the photo below recent sale prices have been strong and a great deal higher priced than what I have just paid. These are certainly popular little camera’s with the younger generation.

I guess we will just have to await its arrival to assess the flash issue. I’m very confident that I will be able to get this camera up and running again.

Assessment:

Out of all the Instax cameras I have dealt with lately, this has got to be one of the best ones I have had my hands on. This is a mid range instax camera that is more sober in colour aimed at those who enjoy their lomography or better quality instant photography. It certainly looks good, and to be honest I’d rather carry this one around rather than a bright pink one.

As posted in the description above it is in near perfect condition and a quick Look at the flash head shows that the flash bar within the unit is broken.

Let’s get on with replacing this damaged flash unit.

Repair:

Let’s get it opened up.

People laugh at me when i tell them that playing around inside these units could kill you. I can understand the contempt aimed at me for such a statement, when I’m carrying a bright pink camera that hardly looks dangerous. Just look at the voltage still in the flash capacitor though once I have opened it. Savage.

Residual voltage of 267v still in the flash capacitor

270v would quite easily send you across the room, if you had a heart condition it would probably be game over. I’ve learned my lesson in the past so I ensure I use a capacitor bleed probe before I go anywhere near one of these flash capacitors. The capacitor on this camera is rated at 320v, not to be messed with. Beware. What’s more impressive is that all this energy is supplied from two 1.5v AA batteries. Clever stuff.

I have a donor flash bar in an old spare unit. I have carefully unsoldered its connections and gently removed the very thin glass tube from the donor unit and placed this in the one situated on the new camera.

Carefully, once inserted into the flash reflector, i have soldered it back onto the board. All looking good. However I need to test the flash so I temporarily put the case on, bung in two batteries and turn the camera on. Press the exposure button and the flash fires perfectly. Happy days. I now can confidently reassemble the camera back together, and I’m pleased that when this is done there are no screws left over. All small wins.

I have some film available so there is no better time than the present to give it a try.

Result:

Nice flash – working

I’ve loved doing this repair, this is a good quality, great condition, and now in perfect working order camera, brought back to life with many more years of use left in it.

But it could have been just chucked in the waste. I’m keeping this one for my collection as it’s a fantastic example acquired at a very good price. Thirty minutes of attention is all it took.

Another one kept from landfill.

Many thanks for passing by. Always appreciated.

Kodak printomatic digital instant camera

I’ve just purchased three of these cameras for a total of £24:98GBP. All non working of course but when healthy they normally command a price around £35:00GBP each. Here is what the listing said for each one:

Camera one:

Kodak Printomatic Digital Instant Print Camera

Camera does not print

Can be repaired or used for parts

EBay

Camera two:

Camera is in good cosmetic condition.

Camera doesn’t charge. Battery charging light flashes but it doesn’t hold battery.

It hasn’t been tested further.

EBay

Camera three:

Please look at the photos carefully, as they make up the majority of the description.

It has two faults

The springs on the back are broken, meaning the rear metal plate is bent , and it often doesn’t push photo paper through correctly.

The shutter button is also depressed.

EBay

This third one might be a longer term repair as I’ve never known a quick fix for a depressed button, that requires a psychiatrist… (That’s me just trying to be humorous, I’ll grab my coat and leave now 😂🤦‍♂️)

To be honest the issue with the third camera seems to be a regular problem based around the design of this camera. Too much pressure on the button normally results in the switch inside detaching from the main board, it’s poorly positioned at an angle and usually not soldered in place too well. The springs should be an easy fix.

I’ve brought these cameras from three different sellers. if I’m lucky I’ll be able to get all three up and running, worst case scenario is that I use one for spares and have two good working examples.

Anyway I’ll just have to wait for their arrival to assess them all, and decide what repairs are required. In the meantime here’s a little bit about these cameras that are again very similar to the Polaroid “Snap” camera range, that also use zink paper. And seeing what is quoted below, the Polaroid “Snap” and this Kodak Printomatic are in all aspects one and the same camera.

Well, since Kodak doesn’t really make its own consumer cameras anymore, the Printomatic is actually being produced by a company called C+A Global, which is just licensing the Kodak name and branding. C+A also licenses Polaroid, and was behind the two-year-old Snap. Both cameras were designed by Silicon Valley firm Ammunition Group, which confirmed to The Verge that the Printomatic is basically the same camera as the Snap, though simplified and rebadged. (The cherry on top of this corporate synergy sundae is that C+A also works with Zink.)

Released 2017

The PRINTOMATIC camera instantly and automatically prints high-quality, full color photos with point-and-shoot ease. It uses KODAK ZINK Photo Paper, so no ink cartridges or toners are needed. The photo prints are durable, water resistant, and adhesive backed for extra fun. The camera’s speed allows you to shoot a new photo while printing the previous shot. The KODAK PRINTOMATIC is fast, fun, and easy to use.

Kodak Ltd & The Verge

The reviews all vary, from very good to downright diabolical, I’m not really surprised since Kodak “Hoared” out its brand name to the lowest bidder many years ago. Am I bitter? A little, as I used to work for Kodak in the days when they were a world leader, the mistakes they made, the decisions and leadership were absolutely awful. And the fact that their demise has lowered my pension pot by about 40% due to their financial mismanagement is another axe that I regularly grind. Yes I am bitter, and since I’ve recently repaired and reviewed their competitors cameras I thought I’d give these a try. Will I be impressed or disappointed? Who knows but I do have an inkling on which way this may swing. But for what I’ve paid for three cameras I’m not really that fussed, it’s just pocket money.

Assessment:

Camera one:

Apparently doesn’t print. Well I’ve put a couple of sheets of Zink paper inside and two pictures were produced. The sd card slot is fine, the charging port is in good condition. Transport is working perfectly. It certainly does print. Just needs a bit of a clean. To be totally honest there is nothing wrong with this camera and for an outlay of £8:00GBP in total I have a working bargain. Kerching – a rare EBay win.

Nothing more to do on this one. So on to camera two.

Camera two:

It’s a bit grubby cosmetically but nothing that a light clean wouldn’t sort. This particular one cost £8:99GBP all in. It was dead on arrival so I’ve checked that the charging port was ok, and then put it straight on charge.

I’ve also given it a light clean whilst charging and the overall appearance has greatly improved. I must just be patient and wait and see if the unit does take a charge, or the original fault appears.

Whilst on charge the originally mentioned fault appears. The charging light was showing a steady red, it is now a rapidly flashing white light with the occasional steady red indication for all of a few seconds and then it’s back to the rapid white indication and it then all repeats. I’ll leave it for a while to see if there is an improvement, the battery just might be so dead that the inbuilt battery management system may just well be refusing to cooperate.the on/off button on the front doesn’t work as well, this might be also related to the battery issue.

Camera three:

Looking very nice and cosmetically very clean.

This one cost £7:99GBP all in. This one is reported to have two issues, a damaged paper pressure pad and a button stuck in the depressed position.

Paper pressure pad is bent and missing two springs

But first I’ve put it on charge to see that it charges, I’m pleased to report that everything is alright in that aspect, and I’m pleased to say it charged fully with the correct lights illuminated. The white light on the top by the exposure button is flashing as a result of the button being stuck in the depressed position, I believe.

This one will need the paper pressure pad repairing as well as the button that is stuck in the depressed position.

Repair:

Camera one:

See above. No repair required. Just a light clean and some TLC. Why did they sell it as damaged? Who knows just what goes on, in the mind of an EBay seller.

Camera two:

This will need to be opened to get near the battery. We may well be able to get the battery to accept a small charge and this may be just enough to fool the battery management system in the camera to take over and continue charging.

Cover off I’ve checked the battery readings and it’s reading a healthy 6.5v and as it’s a 7.5v rated battery I believe this to be healthy, it holds a steady charge the battery is fine. Looking at the led lights they are capable of two indications, red or white and that’s it. I believe the charging light flashes when it’s charged as it cannot possibly show a green light as there isn’t one. This is confusing as normally a flashing white/red light normally indicates that the battery needs charging. Everything that is happening goes against what the producer has published regarding the led indications. But I am convinced the battery is good despite it not turning on. Hold on, I think I’ve found out the problem here…..

It appears that someone has been here before me or that the on/off button ribbon connector has disconnected itself over time. Either way it’s not where it should be. I’ve put the connector back in place and secured it. I now have power and control of the camera.

All lights working, transport whirring away let’s put some paper in to give it a try.

Well it prints ok, all pictures appear to have a “blue tint” to them, however there are big tramlines across the print as you can see, this indicates a dirty roller. What I’m going to do here is peel half the backing of a sheet of Zink paper as the back is adhesive allowing you to stick photos on whatever takes your fancy. By running a half sheet of exposed adhesive, upside down through the camera with the adhesive being the trailing edge, it should allow any debris and dirt to be collected on its way through. I will do this three or four times and even though I will no doubt get error lights appear I can just reset the camera with no further issues.

And that worked. The tramlines have gone.

Tramlines on bottom left picture as a reference. All other pictures now clear.

I’ve also tried the black and white mode as you can see above. I’m very confident, in fact I am positive this camera is now working as it should. I have also put an sd card in the base and all pictures are being recorded as expected. A quick clean and we now have a perfectly good working example of this camera. Let’s move on to camera three.

Camera three:

We have to open up the camera to get to the issue with the button.

The paper pressure pad needs to be dismantled, straightened up and two compatible springs need to be found to keep the required pressure in place on the paper pad. I’ve dismantled the pressure pad and straightened it out, just needs a couple of springs to complete, I’ll sort these out later.

On opening the camera it was as clear as day that the depressed button was as I first thought, the three solder points below it had come loose, no longer making contact.

It’s plain to see in the pictures above that the button that is damaged has all three points of contact broken. these need re soldering to strengthen them. You can see this issue in the microscope pictures I took below.

The switch has been tested and it clicks and operates as expected, this is a known weak point with these cameras and a design fault as well, although the manufacturer would probably deny this. It’s a given fact that the manufacturer wants to sell as many as these units cheaply to the throw away consumer, you only have to look at the main board below to see this…

It really saddens me to see the levels the Kodak name has sunk to, these units are just replicas of the Polaroid touch/snap range, but even at this stage in the repair the Polaroid versions are far superior. Quality control and the cheap design of these Kodak units is borderline awful.

This unit is proving to be a right pain in the ass. The original fault with the exposure button has been repaired and the paper pressure pad is all but repaired, but it seems that being hidden by these two faults is a totally different issue. I have had this camera completely dismantled and have also separated the printer from the motherboard, but this issue of the permanently flashing white light still exists, so the fault is definitely only being carried on the motherboard.

I’ve checked the motherboard thoroughly using my microscope and there is nothing glaringly obvious at fault. I have checked for shorts on the board of which there are none. The only issue I found was that the lens ribbon cable was sitting off centre, however I corrected this but the flashing light issue still remains.

There are two faults that are connected with this flashing white light. One is that the light occurs whilst printing, this is not the case with this unit as it even occurs as stated with the printer disconnected. The other possibility is that it flashes when doing a firmware update, I have attempted to update with the latest firmware and the only difference is that I cannot turn the lights or camera off at all, I have to crash it by removing the battery.

It’s looking as if this could be the issue. The previous owner has probably bricked the unit by interrupting a firmware update and it has corrupted the system. I’m going to have one more attempt at updating the camera with a clean unused sd card to see if there is any possibility of recovery. If this cannot be done then this unit will become a spares unit that to be honest I’d rather not have as I don’t really want to purchase any more of these cameras. But you never know, someone may want one repairing.

Result:

Well in the wise old words of Meatloaf, I guess “Two out of three ain’t bad”. The grey one is bricked, as after numerous attempts of updating the firmware it just isn’t having it. It is just a brick. However there are numerous spare parts that can be used including a good battery, lens mechanism and a number of other pieces. I just didn’t want that though as i don’t really see myself going out of the way to obtain another one, they are as cheap and nasty as you could possibly find. The Polaroid versions are of a far better quality in my opinion, and they are hardly high class.

The positive here is that 3 cameras, quite obviously built for the throwaway generation have been saved from landfill and can be used again. What I’m going to do with the two I have is probably put them both back on to eBay to recover my out goings. If not, I will pass them onto our local hospice to sell on.

Been an interesting fix, but I’m not venturing back to these Kodak models anytime soon.

Thanks for passing by. Always appreciated.
