I have a X files I have been working on. I have a problem that is over my head, let me try to explain. First this machine will work correctly almost all the time but every once in a while at random game play the playfield lights all blink real fast and the flippers go dead. The ball will drain and the scores will add up it and get ready for next ball but the game will just hang up there with only music playing for 50 sec to a min. then kick the ball to next player or ball up, then work fine. Anyone ever have this issue or can help me diagnose it. Thank you
