SEGA Game Gear
The main reason why Game Gears fail is because of capacitor plague. Poorly made capacitors were used and they unfortunately leak all over the internals. Before any real work can be done, you first need to recap the main board, power board, and audio board. Places like Console5 sell capacitor kits for each model. If there is capacitor leakage on your board, it is crucial you clean all of it up, otherwise it will just continue to corrode the internals. Best way I found to remove it is to use IPA and a brush to scrub, then followed by IPA and a q-tip. After a full recap you may still have problems. First double check to make sure you soldered everything together correctly before continuing
