I have a problem with my Gameboy Color

i I have a problem with my Gameboy Color I bought. First of all the original power switch was toast, it simply fell appart. I bought a replacement and soldered it on.

When the switch is in the on position and I put batteries in, everything is fine.

When I turn the switch off, it turns off (although the last picture stays for a while on the screen) But here comes the issue. If I put batteries in while turned off, and I turn the power switch on, the power light just flickers shortly but the console does not turn on. This is repeatable.

Switchposition ON: put batts in, works fine

Turn OFF, Gamboy turns off, although picture remnants.

try to turn on again, Powerlight flickers but nothing happens...

I desoldered it already, to check if there is no short cleaned it up once more with alkohol, resoldered, same issue.

The problem seems to come in the transition from pins C + 1 to C+3 which causes something, but I have no clue

Can you upload pictures of both sides of the circuit board? Ajout d'images à une question existante


sorry for just editing now. I forgot to mention that I installed a funnyplaying LED Button board. turns out eventhough everything is mounted just fine and eventhough the led board works fine too, it seems to interfer with something.

Because after desoldering it, the game boy turns on just fine with the switch.

after remounting the led board, the same error occurs again.

So I' m gonna go with a replacement of C32, If this doesn' t change I' m gonna replace the other capacitors as well as f1 and f2.

But I think that C32 being the original power capacitor, it is said they were just made just good enough to make the gameboy run in its original state, and every mod can cause trouble, especially after 25 years


@frenchmax Sounds good. If you need any help finding a replacement capacitor or any help getting the old capacitor off, let me know.

Electrolytic capacitors (spherical can) don't last forever. They should generally be replaced in any electronics 30 years or older or in computers, monitors, TVs, power supplies, routers, and modems from 2000-2010. The capacitors from 2000-2010 will need to be replaced will specific parts, so post another question on the Answers forum if you need help with that


Thanks for your help. I ordered a set containing the 3 caps and 2 fuses, and on top of that I ordered a cap for c32, made specially for mods, because I also wanted to mount an IPS LCD, and eventually a battery mod. But I gotta figure that out first because I think the clean energy comes with a power management board which requires to remove the c32 anyway, but the screen regulation doesn' t work anymore. Maybe I' m gonna stick with rechargeable batteries.
