I have a Gotlieb Roller Disco that works intermittently. When I turn it on, it usually works the first time, but if I turn it off and back on, it comes up in tilt, with garbage on the displays, or coils locked on and a bunch of craziness. I've tried quite a few things to fix it.
The power supply is a rotten dog, so I don't think that's my issue.
The driver and mpu have both been tested in a different game and worked fine.
I replaced the rom chip.
I have repinned all of the connectors to the power supply, mpu, and driver board.
I have completed all of the ground mods.
What else could I be missing to solve this? I'm at a loss here!
Thanks for the help!
