Issue with Williams Blackout. Occasionally the player 1, 2, 3, 4 lights stop working during gameplay. They can start out working thru each player but then stop working. Next ball they may be working again. Game has a new CPU/driver board. We have reseated the IDC wires on the female headers, checked and reseated the wiring quick disconnect to the light board and visually checked all sockets and connections. It feels like a connection issue rather than a board issue but just can't put our finger on it.
What are we missing?
