I've got a Mr.& Mrs. Pac-Man Pinball that has been having some issues when turning it on. It doesn't post. So no startup sounds, though there is an audible hiss from the speaker, and the big red light on the playfield. Wait about 20-30 minutes, turn it off and on again, and it starts up just fine and appears to play as normal.
Potentially some cold solder joints or bad connectors is what I'm guessing. I'm assuming I'll get some advice on soldering headers and re-pinning connectors.
If someone has specifics--such as this is a mainboard problem or something I might not be thinking of, that's what I'm here for!
I'll gladly take advice for some basic tips on bulletproofing connectors (where to source parts, technique, etc.) on a Bally machine. If there's another post on this, please don't shoot the messenger and feel free to point me in that direction.
Cheers, and thanks for the help everyone.
