Hey ya'll,

So I have a HD graphics text gen 1 Genesis. Since I got it, it powered on fine but just flashes white and then black screen. I did get past the license screen once or twice in a game, but it froze up after that. I took it apart and cleaned and inspected it best I could, cleaned and bent the cart reader pins out to make sure that was fixed, and still get the same issue.

I have another genesis so I don't really need this one, but I would really like to know what else to do to fix it. Seems most people online just say "buy another one" because they are cheap. I may just sell it, but I'd like to figure out the issue. I'm decent at small electronics and have most of the needed tools (multimeter, good solder iron, o scope). If i know how to diagnose, I can do it. Ive fixed a few amps and built a few effect pedals here and there, calibrated my tape machines, but if I don't know what to do first i'm kind of stuck.

Has anyone else had this issue or are there some chips I need to look at testing?
