So with both the original MPU (had too many issues with it so I replaced it with a Rottendog), and after the new Rottendog was installed, at random times during attract mode the game will 'freeze' where all 4 displays go blank, the inserts shut off, and only the GI and backbox are lit. The game is in kind of a 'limbo' mode like it's waiting to boot. It's just like when you first turn it on and only the GI/backbox light up and after a few seconds the game boots, but nothing ever happens. I have to reset the game and then it works perfectly again. If I let it sit in attract mode, it will eventually happen again but it's at random times. Not an MPU issue since it happens with both the original and the replacement. I imagine it's a voltage issue but it's never happened during actual game play. Only in attract mode. Anyone encounter this before? I don't believe it's a watchdog or resetting issue since it never actually reboots after the issue occurs. It's like it tries to, but hangs up. Any help or guidance would be appreciated. Thank you.
