Hello, I bought a GameGear in poor condition on a flea market, at least the price was good just for the game included. I recapped the main and sound PCBs; I can hear the music but the screen stays like that, whether there is a game or not: I found this video, where you heat the black chip on the right (yeah, don't laugh too hard). Since I had nothing to lose, I tried, but nothing changed. Is there something I could try, or is it definitely dead? Thanks.
I checked each pad of the ribbon, and all of them are correctly soldered. It seems that I can't do much more, except this TV output mod.
I would go back and re-check all of your capacitors and make sure they are oriented correctly. The only time I haven't been able to fix a Gamegear screen is when they were physically cracked, broken. You can even fix it if the ribbon has pulled from the motherboard. Also what kind of capacitors did you use?
