If you can't coin it up and hear the game play, then odds are the PCB isn't running. Check the ROM chip sockets. Usually it gives a solid color screen when it's not running.

I think that's right per the schematic and wiring diagram. I made a JAMMA adapter for MC to test boards, and I think I had to set it for positive sync to test properly...
