I shopped my game out recently and one of the problems I was having prior to the shopout was with the racetrack. Today I went to farther diagnose my racetrack problem. When I turned the game on I noticed the ZR1 and racetrack didn't do their thing at bootup like they normally do. Both were functioning last night by the way.

I re-seated all connectors and did a visual and everything looked ok. I turned the game on and noticed I have no lit led light on the board in the backbox. Does this board control both the ZR1 and racetrack? Could it be one of the ribbon cables went bad? Is there anything I can do to check or diagnose the problem?
