I have a scared stiff that will not boot up. The backbox lights will come one but nothing else. If I disconnect the J601 Ribbon to the audio visual board and the game will turn on and the rest of the lights will turn on. The second that I try to reattach the ribbon it turns back off. I swapped out all the ribbons to see if that would make a difference and it did not. Should I try to swap out a audio visual board from another game to trouble shoot? Any advice.
