Here are some pictures I took while I was working on it. Next time I open it I'll try to take more. The front of the board looks immaculate and shows no corrosion, but unfortunately I haven't gotten a picture of it yet:

Topic: Gameboy Pocket - Messed Up Controls (1 replies, posted in Nintendo Handhelds)
Hey guys,
The other day the controls on one of my gameboy pockets started acting up. A and B were acting as left and right, and down was acting like start and sometimes visa-versa. I'm guessing there's a short circuit somewhere but the problem is that I can't find it.
I opened it up to clean it and the first thing I noticed was a heavy amount of corrosion around the negative terminal. I cleaned it up as best as I could but the issue is still there. I went over it with some alcohol and cotton swabs about 3 times over and while the issue is less frequent, it's still there.
Has anyone encountered this issue? I'm thinking about removing the battery contacts and replacing them since there is still a little corrosion that I couldn't get out.
I'll post some pictures as soon as I get a chance.
Any advice you guys have would be great, thanks!
P.S. Also, where can I get battery contacts for the pocket? All I can find are ones for the DMG. If you know any sellers that have them please post them. Thanks!

Hey guys,
I realize this is a little bit late (6 years), but I just got a DMG off of eBay with the same issue. The seller had mentioned there being corrosion and upon opening it I noticed some of it spilled into the board with the headphone jack. As Nitro2k01 mentioned, it was the switch in the headphone jack not making contact that was the issue. All I had to do was clean it with a little bit of alcohol, plug and unplug my headphones a couple of times and voila, it worked!
In short, if you're having this issue, try cleaning the headphone jack out and plugging and unplugging some headphones a couple of times to fix it! For anyone else having this issue, I hope this helps!
P.S. Here's a link explaining the same issue and how to fix it:

Unfortunately no. I feel like there might be some broken connections somewhere I can't see, but it's definitely getting power because all the pixels are on when the console is on. I think it might have been salvageable at one point because the screen was just blurry, but after fiddling with it and leaving the screen on too long, I started seeing those weird artifacts and now it seems like it's just toast. I'm holding on to it for spare parts for now, maybe I'll revisit it at some point.

Also, I believe the contrast potentiometer is working fine because it was working fine before the mod and I checked it wit my my multimeter and it seems to be working correctly. Unfortunately I think the screen is just toast

Re: DMG - All Black Pixels (7 replies, posted in Nintendo Handhelds)
Alright, thanks guys! I tried running over those connections again and still no luck. I've got another DMG on order to replace this one so I'll just be extra careful this time. The last backlight I did I had no problems but for some reason this one had a crazy amount of adhesive on the glass that didn't want to come off. The reflective layer came off pretty easily but the residue that it left was really bad. Maybe I used too much alcohol when trying remove it, I'm really not sure. Any advice on removing the reflective layer/cleaning the residue next time?
Also, in case you guys are curious I got a photo of the diagonal lines. I've never seen anything like it before:

Hey guys,
I'm having an issue with one of my DMGs, when I turn it on all the pixels are black (on) and the contrast wheel doesn't change anything.
I was attempting to do a backlight mod but I think I may have damaged something while cleaning the adhesive off of the screen (after removing the reflective layer). At first it was just blurry but now it's completely black. The sound is still functioning so the PCB board seems to be working fine.
I noticed a couple of broken connections on the cable behind the screen so I tried soldering them but still to no avail. I also notice some strange diagonal lines that fade out when I turn the system off. Also, the longer the system is on, the longer it takes for the screen to fade when I turn it off. Have you guys encountered anything like this. If so, were you able to fix it?
Any advice would be great!
Thank you,
Joel
