Very faded LCD display 24 Mär 2011 00:35 #4533

Hello all, Very new to the forum and I am so glad to see a forum dedicated to these marvellous little machines. Recently I have taken to playing my old retro gear. Today I got my old game and watches out - I quite happily played donkey kong and then mario bros but when I got to donkey kong 2 I turned it on and.....calamity..... the lcd is faded to the point of barely being able to see it. If you hold it in a certain direction you can just about see it and from that I know it still responds to the controls plus the sound is excellent. I'm really not sure what to do and I'm hoping that it can be fixed somehow. I remember getting it from the local co-op back in the 80's as a pressie from my mum and dad and I played it for hours so it has great sentimental value.
oh btw, I have tried new batteries as well - both sets have been energizer lr44 and work fine in donkey kong and mario bros.
Please please help

Hello and welcome here

A faded display could be a problem with the foil or the LCD itself.
You could buy a rather cheap lose game of the same kind for spare parts and then exchange the weak parts.:-k

Hi Patrick, Thanks for replying. I did see the foil when I opened it up but I'm a complete amateur - which is the lcd?
Thanks
Andrew

Just tried a different set of lr44's this time duracell and still same response so at least we can rule out batts. Any ideas where to get a defective donkey kong 2 from as those on ebay all seem in great condition and are way too expensive.

Also where is the lcd? I have found the silver foil which looks darkened in areas but where is the lcd?

The LCD is underneath the foil (at least it should be there :-k )

The best and most cheap way the get a DK 2 for spare parts is to look out on eBay. Most games are in great condition and expensive as you mentioned, but once in a while there are games in bad condition as well. Full of scratches for example, but still working.

You need to be patient. :)

Or you may ask other collectors, but I guess most collectors have their games in great condition :mrgreen:

I also have 2 Donkey Kong II games with the same LCD problem. But no other Game&Watch with this problem in my collection. I am wondering, if Donkey Kong II is extra susceptible for this problem, or this is just happened by mischange? Or have some Donkey Kong II series a manufacturing fault?

@Chainsaw - I don't know but I'm hoping when I have swapped the silver foils over that I will have a working version once more

I joined up just to reply to this topic, just to concur. I also own multiple G&W units, but only the Donkey Kong II console seems to suffer from exactly the same problem, despite my best efforts to preserve it in a safe place. I was wondering if in the meantime someone was able to solve the problem, maybe with spare parts from another console?

Greets,
Wes

Hello Wes and welcome here

I usually get a cheap game (for example one that isn't looking nice on the outside) for spare parts and then I exchange the broken parts.

Hi All,

I also just joined up to reply to this topic. I fount this topic by googling for the exact same issue described here. My copy of Donkey Kong II also suffered from extremely faded graphics.

I figured out that (at least in my case) this was caused by a fading of the polarized foil that is the top layer of the screen. You can easily check if this is the case with your unit, by looking at the screens through a pair of polarized sunglasses (I guess those polarized glasses used in cinemas for viewing 3d movies also work EDIT: 3D glasses from the cinema appear to be polarised differently and do not work for this. Try polarized sunglasses (Polaroid) instead!). If the problem is indeed a faded polarizer you should be able to see the crisp black sprites the way they should look by turning the glasses until the polarization direction matches up with that of the game & watch screen. If this works, and viewing the screens through the glasses gives you nice crisp sprites again, the problem is relatively easy to fix.

I was able to fix my game by simply inserting a new polarization filter. To do this I ordered a sheet of polarized foil online, figured out the correct orientation of the foil for the screens, cut it to size and replaced the original polarizers with it. Since the new foil is slightly darker than the original the screens have become a bit darker than they should but at least every sprite is nice and black again and the game is very playable like this. I don't have a camera right here right now, but if anyone is interested I could try to take a picture later.

The reason this fading problem appears to happen to only Donkey Kong II could be that Nintendo used a lower quality polarised foil for at least some batches of these units than for the other Game & Watches.

If anyone is interested in fixing their copy of Donkey Kong 2 (or any other G&W with the same issue), but doesn't want to order a sheet of polarized foil themselves (it's relatively expensive stuff), I've got quite a bit of the foil left, and I would be perfectly willing to send some pieces cut so size to anyone interested for a couple of bucks. If you want to try it out yourself, the filters for the dual screen G&W are 6 x 4.5 cm. This page gives a nice walkthrough for disassembling, cleaning and reassembling a multiscreen Game & Watch.

Regards,
Chris

Thank you for your information. I also own 2 Donkey Kong II with this problem and I will check them with the 3D glasses. It really seems, that Nintendo used a lower quality by Donkey Kong II as you wrote. AND what a luck, that they did this only by one game. My third Donkey Kong II also have the problem, but only a little bit and it's still playable.

PS: Oh, and thanks for the link about disassembling/assembling.

I have a Donkey Kong Game and Watch and it has a faded screen as well. I inspected the ribbon cable that is in between the two screens and I noticed it has a tiny hole in the middle of the cable. Could this also cause the faded screen? Just wondering before I attempt to fix it. Any help would be much appreciated!

Hi GameLifter,
I think that if one of the contacts in the ribbon would have been damaged by the hole there would be no overall fading of the screen as a whole, but that the part of the screen controlled by that particular contact would not display at all. I am not 100% sure if this is how this works though. (You don't mean the holes that are supposed to be in the ribbon right? As seen here .)
As I described above you can easily check whether the fading is caused by fading of the polarised foil by looking at the screen through the glass of a pair of polarised sunglasses (polaroid). I have now tried to use the 3d glasses from the cinema to check, but this does not seem to work as I thought. I guess those 3D glasses use a different kind of polarisation. So try polarised sunglasses.
Make sure you turn the glasses in every direction to find the correct polarisation angle. If there is an angle that makes the sprites visible again you can fix the G&W by replacing the foil.

Chainsaw,I was curious to know if you were able to fix yours?

Oh, I don't have the abilities or skills to do repairs on these games. But I also tried a "faded" Donkey Kong II with some 3D glasses. It also didn't work, the game still looks "faded" through the 3D glasses...

Ah, it appears the holes in my ribbon cable are the ones that are supposed to be there. Also, both of my screens have fading throughout the screen. It is most likely the polarized film, then. I don't have a pair of polarized sunglasses on hand to check but from reading this forum thread and doing more research it seems like the polarized film is the culprit. Is there a good site on the internet to order more polarized film? I may give this fix a try. Thanks for all the help!

I ordered both a normal polarisation foil and a LCD foil to try out. The LCD foil turned out to be to dark so I'd advice the regular polarisation foil. I've got quite a bit left that I'm not doing anything with and would have no problem sending you a piece for both screens. Just PM me if you are interested.

Hey all.
Yeah I reckon Nintendo got a dodgy batch of that stuff.

Cheers

Hi Picklegell,
Sure, just PM me your details and I'll check how much the postage will be.
Regards,
Chris
