[Jukebox-list] Off Topic - Pinball Help Question

[Jeremy Agema]

I have worked on those types a couple of times.

It seems like you need to look at the board with all the high power 
transistors on it. This board also filters power for the displays. You could 
have a touchy transistor - try the solenoid test.

It's easy to get a wiring problem or connector issue with all those tiny 
pins.
