Hi, all! I have a Heavy Sixer that, after a good cleaning, seemed to be working fine. I booted up Video Pinball and was playing through a second game when the game failed and goes all distorted, kind of like when the contacts don't line up properly between the system and cart. I had been playing on and off for about 15 minutes at that point, Super Breakout, then Kaboom!, then Video Pinball. It sounds to me like something is overheating and causing the failure after a little play time. Any suggestions on what I should be looking for/replacing/resoldering/etc.?
