I have a Game Gear that I repaired recently with a power board replacement, and a week later, it stopped working again. When you turn it on with a game cartridge inserted, it just shows a scrambled mess or a solid color that glitches out into black. I opened it up, found some capacitor acid, and cleaned up the front and the back of the board of any acid using isopropyl. It is also recapped. Is it a cartridge slot problem? What can i do to save it? I have a VA5 Game Gear. Most of the time it shows a corrupted license screen that goes nowhere.
