The MP I have does not want to have sound. I plugged two working boards in and nothing. I also just put in a rebuilt power supply. Any ideas on where to turn?
 
Plugged into what? Dedicated cab? JAMMA cab with adapter? If so, what JAMMA cab?

Have you checked the speakers and the wiring from the edge connector through the harness to the speakers?

Speakers wire!

When I switched out the monitor on my moon patrol I popped out the speaker wire from the connector.. Did the same thing, tried 2 pcbs and messed with the PS.. mine was just a loose wire.. start with the basics
 
Moon Patrol Sound problem

Hey, I've heard of a few people now having no sound in their Moon Patrol cabinets...has any one found a solution to it? I just wired mine in a conversion cab, and everything works great except, no sound. I tested all the basics; tested the wiring, tried 2 speakers, made sure I had the right pinout (its supposed to be pin 13/P), adjusted the volume knob, and reseated the sound rom, and still nothing. Is it a problem on the board or am I just missing something? Any help would be appreciated.

Thanks

Doc
