I'm trying to repair a gamecube for a cousin of mine, and have hit a wall. The system will start up fine, load a game, and then in random spots will give the 'can't read from disk-read your manual' message. I'm wondering if there is some kind of thermal overload connected to either the motor or laser... After I finally got the case opened ( boy is that fun..) I was working on it right next to an air-conditioner, and it seemed to stay running for longer periods of time. Also, the time it takes to shut down decreases with each subsequent attempt. Any Gamecube Guru's in here? Any advice would be much appreciated.
