First attempt at Retrobrighting

I’m currently deep into a repair project that I will be posting about on here shortly. However the shell of this project has aged so badly it has earned the right to be my Guinea pig for my first attempt at Retrobrighting, it deserves a separate post of its own, so it’s getting one. I have explained what Retrobrighting is in a previous post: Retr0bright – What’s that then?

The unit is a recently purchased and damaged Nintendo Gameboy printer from around 1998, it isn’t working and looks right ugly. It needs some attention to its fascia and battery base, so let’s get on to it.

I have taken the entire unit apart, separated the parts that need to be treated, removed all labels, and given the offending items a thorough wash in detergent before drying them off.

All stickers and other items removed. Shell thoroughly washed.

Next I’m just putting a 40 Volume 12% Peroxide cream solution into a small bowl, and I will then place the shells on a piece of cling film where I will liberally coat the offending items, using a brush, with the solution. When I’m happy with how this has gone, the treated surfaces will then be wrapped in cling film and placed in a sunny position for around 12hrs to allow the sun to do its thing. (UV lamps are sufficient if you have one available). I must reiterate it is important to wear protective gloves and eye protection when using this solution.

I’ve given a good coating of peroxide formula to all surfaces, but is it enough? I won’t know for at least a further 10-12 hrs, time will tell.

With the peroxide now applied, the fascia’s are now all wrapped in cling film and ready for 10-12 hrs or so of intense sunbathing. (Sounds just like me on one of our visits to Cyprus!). So let’s wait a while.

I’ve checked in and looked at the pieces outside, and after just 4hrs the results so far look amazing. I’m going to give it the full time though, so I’ll be back in around 6-8 hrs to check results. Hopefully we will have sufficient sunlight until then.

I’ve terminated the process at 9hrs as I have to go out and I’m impatient. Boy am I impressed at how it has turned out, it looks like a new shell.

Well I can honestly say that this treatment does work. I’m so impressed at the outcome, I just wish I’d attempted it earlier on some of my other products.

Anything I’d do differently? I’d probably slap on a little more solution or maybe even reapply about half way through the process, the only reason for this is that there is the most minute tiny tinge of a yellowing on the side that had the heaviest contamination, possibly if I hadn’t been so impatient and left it for 3 more hours it would have been sorted, but then again it might not have! I do think a further application at the halfway point, especially when an item is so heavily stained as this unit was, would have done the job and made it look even more perfect.

Am I coming across as disappointed? Well I can assure you I am not. It’s my first attempt and I am so impressed. The total outlay for this process was £1:85GBP and that was just for the 75ml bottle of peroxide from a local supermarket, and I have enough left for another 3 applications, an absolute bargain. We only learn and improve from being persistent, and I’ve already learnt from what I have attempted today. And i am already a better, and more knowledgeable person than I was only a few hours earlier. You certainly can teach an old dog new tricks.

Edit: some 12hrs later I have decided to give a second treatment to see if this can improve on that slight yellowing I mentioned earlier. The results have greatly improved the look and there is now no visible sign of yellowing. I’d certainly recommend a second treatment for heavily stained items. It works, extremely well.

Tomy / Palitoy Missile strike

Here’s what the listing stated:

This is a nice example of a Tomy ‘Missile Strike’ electro/ mechanical handheld game. It was made circa 1979 and is battery operated. It appears clean for age and works, apart from the missile light not illuminating. Battery terminals very good. This is a nice genuine item that is shown as I found it. NOTE – NO BATTERIES ARE ENCLOSED. Nice example for any collector.

EBay

On first seeing the listing for this item, my thoughts are that it looks quite clean and tidy. The usual state of these units are quite tatty with scratched screens. This looks good, however pictures, especially from EBay can be greatly misleading so I’ll guess I will just have to be patient and wait.

This units only issue seems to be with the LED missile light, so hopefully it will be a quick fix. These units are currently selling between £52-£79GBP as per the picture below. I managed to secure my unit for a total including postage of £24GBP so I think I’ve done well in that aspect. I’m quite happy with this.

A little history:

Tomy released Missile strike in 1979 in its international line of electro/mechanical handheld games. Known under different titles in other regions such as Terra-Hit (UK), Missile Strike (UK), and Space Attack (Japan). One of TOMY’s electro-mechanical handheld games, Missile strike is a Space Invaders-like shooter game, the units small motor winds strips of aircraft across the screen, which the player attempts to hit in order to earn points. There is a mechanical wind up timer that controls the action, and the purpose is to score as many hits on aircraft as possible with in the time it takes the winder to stop. The game includes one small, flashing LED light as the exploding missile.

So it’s another game that has reached its 46th year, and for the only issue to be its one light source, I think that’s acceptable. Let’s wait to see what arrives.

Assessment:

On arrival the first thing that hits you is that this is yet another filthy item. I seem to attract these kind of sales, so it will require a deep clean. Cosmetically the game is in good shape with no deep scarring and only minimal fine scratches on the screen lens commensurate with its 46 year old age.

It was sold as the missile light not working, this is partially right as it is an intermittent fault, I suspect this is down to dirty contacts.

This game has two bands of film that run across the top of the screen displaying aircraft, the top band is intermittent and needs attention. The score counter will also need attention as it is not turning smoothly, again I suspect this to be as a result of the build up of dirt.

Repair:

First thing to do is dismantle the unit and to get some cleaning done. The small video below shows the issue with the top band aircraft not moving.

Film transport fault

I’ve taken the counter out after removing the case and all exposed buttons and switches.

Off to the kitchen sink. let’s get these items washed.

Whilst I’m waiting for the washed items to dry I clean the counter mechanism of old dirt and fluff.

Counter mechanism cleaned, fluff removed. Silicon grease applied

I’ve slightly greased the counter with silicon grease and it’s behaving well and doing what it should. This will go back in place when we do the final reassembly.

The issue with the film movement was a strange one. There was no way to tension the two capstans that the film roll over and there were no teeth missing off the capstans. One capstan pulls whilst the other pushes, all I’ve done is swap these around and the issue has disappeared. About as simple a fix as you can get.

I’ve put a little before and after video here that shows the effect of swapping the capstans around.

How swapping capstans worked

The issue with the intermittent light was easy as expected. This is the only electrical piece on this game and it was down to contaminated battery contacts that just needed a bit of a clean with my grinding pen and a wipe over with IPA.

Final little touch was just to accentuate some of the old lettering by the timer. This was just with a white paint pen.

Now we can reassemble and test again.

Result:

The game has been reassembled and tested and is now working fine. All intermittent issues have gone and it has now been polished and now looks superb.

I’ve attached this small video that shows the game working as it should, with no film slipping and lights and counter now working.

Working perfectly

It’s really pleased me this repair, as it’s another one of those mainly mechanical games. Dirt featured big time, and age issues have been overcome and the game given a new lease of life. Another one for my personal collection, it will go on now for many more years to come.

The best outcome that was possible, we have another superb seventies product that has been saved from the scrap heap.

And that is the biggest win of all.

Thanks for passing by, it’s always appreciated.

Grandstand – Kevin Keegan’s Match of the Day game

Here’s what the listing stated:

***NOT WORKING***

Spares or repairs

Fair overall condition some cosmetic damage as expected for a 56 year old item

Very rare well worth restoration if you know how

EBay

This guy sells retro games on EBay at exceptionally inflated, ridiculous prices. I suspect he doesn’t get involved with repair or renovation as he had this one advertised at over £30GBP but when I put in a cheeky bid for £12GBP he bit my hand off… I wasn’t expecting that! The usual mistakes in the listing such as stating it’s 56 years old when its actually 46, and stating it’s Very rare – it’s not, there were a few hundred thousand churned out and to be honest and they come up quite often on the sale sites. But I do agree it’s worth restoring and will pair up nicely with another retro football game from 1979 that i repaired a few months ago Bambino kick the goal football game. And what makes this unit even more appealing is that it is complete with both of its battery covers – now that is rare!

This game was made by Grandstand in 1979. Here’s the original advert that appeared on UK TV promoting the game back in the late 70’s.

European footballer of the year 1978/1979 Kevin Keegan – questionable late 70’s advert

This particular unit is listed as Not working, it looks filthy from what I can see, but having experience with these games in the past the biggest issue is age related problems such as old components, track decay and battery corrosion. No doubt the first thing I will do will be to dismantle it, give it a thorough inspection and then a good cleanup both inside and out. And then we can look at the issues around why it’s not operating.
