I'm trying to repair an old gameboy,. Doesn't power on (red light on but nothing else). But then if I short the vcc and gnd on the dmg conv power board it beeps and boots a game and works normally!
I have tried another dmg conv board - same issue. Have replaced the 6 caps on the dmg cpu board, checked board for broken traces or damage..seems ok. Is there anything else I can try? Thanks
