High Speed with 11a board w/ four pin header installed at 1J15. KE (pinballpcb.com) power supply. All GI lighting and attract mode lighting ok. NO sound at all. Game will accept coins for credits. Pushing start button will kick a ball into ball shooter. You can shoot out ball, but the game does not play, no scoring, no flippers, etc. All solenoids appear to fire (I found this out when I pressed start with no balls in the machine). All fuses removed and checked with ohm meter. Also, the diagnostic buttons on the coin door do NOT work.
Your help is appreciated, thanks.

Connectors were the problem, all fixed, thanks!
