I have a Bally Power Play (Bobby Orr) pinball game which has a glitch At any point while playing the game the digital score lights go out. The play field remains lit but the targets etc are all dead.Sometime after a pause of a minute or two, the lights come back and the game goes into game over. Other times it doesn't reboot on it's own. i have to turn the game off. turn it on and it goes live but game over.
It sometimes also takes out the high score data. Checking for power it has a solid 5.0 reading and nothing appears amiss.What's causing the power surge/blackout causing the digital score display to go blank?
Then it will play fine for days or weeks. It will act up once or it will drop out repeatedly. One time, six games in row it crashed, and was fine as of the seventh game for about three weeks
