Quoted from PinballGurus:Well we unplugged the LCD and it still kept popping balls out. There’s 5 balls in the machine, which is the correct amount. Hmmm?
Go to switch edge test. Take out all balls. Your machine should be reporting 6 closed optos on top of each other including the 5 ball positions plus the trough jam. If any one of those are not functioning. The game will behave like this.
