GameBoy Colour not turning on

[Greninji88]

I might buy a GameBoy Colour, it says that it doesn't turn on at all. No signs of life. If I was to get this, how do I fix it? Thanks

maybe put in new batteries

Well that's one thing I'll try...

There's really no way of knowing, is there? Maybe somebody cracked it open and scraped off the PCBs, or something.

I was going to guess oxidation in the power switch, as can happen with the GBA.

In the worst case someone scraped of the PCB.

Might be a bad power switch

Once, I had the misfortune of buying a non-working Game Boy. Sadly, it never turned on again. I tried everything, but nothing helped. Eventually, it was abandoned on a shelf… and it's still sitting there to this day.

Have you tried turning it off and on again?

Dude, if you own a multimeter follow that there's voltage throughout the board.
If there's voltage, then it's definitely the power switch.
Either dirty, or broken.
