On my Revenge from Mars, all the lamps in one matrix column go out intermittently, and when I touch the wire connector to the lamp board, they start working again. The diagnostic says the column lights are "open" when they are off but supposed to be on. Does this mean the wire have a ground problem somewhere in the machine or is the connector bad? I've already ordered a new connector. I have a video of the sparking if that
Thank you!
