Finally got it replaced but still no LED battery light and no screen turning on.

My batteries are fully charged and the battery contacts are clean as well as the back board... at least I think tis clean.

What do I need to do? Is this still fixable or do I need to buy a fully working gameboy

One of my cousin's was getting rid of their old Gameboy which they'd not used in a while so took it off their hands to see if it could be fixed.

The battery contacts had some bad corrosion which I've managed to remove and it now turns out but there is nothing on the screen. I've attached photos of how everything looks. If anybody can give any advice it would be much appreciated

i bought DMG-01 with leaking batteries .

the seller said its used to work but he hadn’t touched it for years .

i completely disassembled the DMG , cleaned all the corrosion with white vinegar and IPA.

put new batteries in . turned it on and nothing , no sound at all and no screen -BLACK.

so i started to troubleshoot the problem . figured out there was some corrosion in the headphones jack so i unsoldered the jack , put it in vinegar , cleaned it and double checked continuity with multimeter, all good with it and it works the way it should .

i soldered it back , and now when i turn on the DMG i can hear *Poop* from the speaker - but that’s it , the same when i plug the headphones.

i checked the sound pot with multimeter and it works but i can’t hear any sound change if i turn it .

for the screen is the same , checked the contrast pot and it seems to work but the screen is black .

no visible damage at all to anything.

any idea to what else i can check , is there any blueprints for Ref that i can follow ?

thanks

I’ve finished installing the backlight and bivert board, but now, the device won’t power up at all. No red power light, no backlit screen.

Has anyone else ever had this trouble? Is it possible that I ruined or disconnected another pin that would affect power while soldering the bivert board in place?

Prior to my install:

• Device powered up without trouble
• Buttons were responsive
• Connector pins were solid; no trouble with reading games
• Vertical lines on the left and right of screen
• I cleaned up what corrosion I could find on the motherboard and in the battery casing

Thanks in advance for any advice!

I installed a backlight and a bivert on my game boy and the backlight looks great and the gameboy worked fine with it but then I tried to install a bivert mod but after I installed it for some reason when I power on my gameboy the backlight turns on but the screen is blank

I know that the logo is a sort of ‘genuine hardware’ / handshake operation, but it seems that this is going wrong on this device.

The interesting thing is, about once every 10 hard resets (just off-on) it loads straight into the game, skipping the logo step entirely.

first , sorry for my bad english , it’s not me mother language

recently I have bought a gameboy , the first one dmg1

I buy it screen broken , thinking that I can repair it easily , but when I opened it I saw the power board totally destroyed

so I have 2 question

1 : where can i buy a replacement for this board without having to buy the complete mother board with it

2 : on this site https://gbhwdb.gekkio.fi/consoles/dmg/

I saw that there is a lot of different model for the gameboy and on each model , the component on the power board have different inscription ( click on “ power board front “ to see the photo )

so even if I find a replacement board , will it be compatible with my gameboy ?

I can’t find my version on this site , so here are all the info I can get :

buy in france so probably a UE model

CPU : DMG-CPU B

RAM : LH5264N4

LCD board : DMG LCD - 06

Jack board : DMG jack 03

power board : I don’t know .. the only thing I can tell is on the black cylindrical component ( I don’t know what this is ) there is written 223 H1N

here’s some photo :

I know I just should buy a complet mother board replacement , but I love challenge so I will try to repair it like that before

thank you by advance for you help

I decided to take it apart and clean it. I put it back together and... Nothing. I left it sitting a couple of hours and decided to try again. This time the screen turned on normally. I was relieved but decided to unplug and replug the top board just in case to see if it would still work. It didn't. I had no sound and no image again.

At first I thought a cap blew. I checked all of them and saw that none of them look bad (I can't check them since I don't own a multimeter). Is it even possible that a cap would be faulty if the screen turned on when I tried but then stopped working again?

I've done some work on the Gameboy and haven't found any shorts.

They don't...

So I put in Mario land and boot it up. the Nintendo logo goes down as usual but after that it crashes. Same thing for Dr. Mario. Pokemon Blue won't even load the Nintendo screen. it just crashes instantly upon boot up. However what's weird is that Tetris Attack and Turok 2 WILL boot up and work just fine except the sound is just obnoxious buzzing, even with headphones. Now, ALL of my games work perfectly on any other console I've tried them on so it ain't my games.

I open it up to see what the problem is and there's battery corrosion all over the back mother board. There's corrosion on the receiver for the ribbon wire where the metal parts connect to the board. The tip of the ribbon wire itself has corrosion on a few of it's connectors.

So I look up how to maybe clean this up. Mainly I get forums saying use vinegar and clean it with rubbing alcohol. I begin to do that. the system itself looks much nicer than before but the main problem areas still look rusted or burnt or something. After all of that cleaning I put it back together and it's not fixed at all. it's not any more messed up but it's still not loading games. I'm confused because if it was completely broke it wouldn't load any games at all! it's just... picky. The buzzing sound is still there too. The LED still doesn't work but I'm not AS concerned with that. Can anyone give me some advice on this issue?

I have recently had a itch to play my original Gameboy. But I when I went to play it there was no power going to the system. I have tried new batteries and a power adaptor to get power to the gameboy, but without any luck.

I have taken it apart to clean the battery connections, in case there is any corrosion, but they all seem to be in a reasonable condition.

Does anyone have any suggestions of what to try next? And are there any guides out there that may help me? I have googled searched, but many of the guides that I have found relate to corroded battery connections.
