Quoted from RC_like_the_cola:Do you have an uneven number of balls in the game? Maybe it's calibrating where the balls are at the start. Maybe a switch isn't seeing a ball. Does it do this for only one side or both and several balls worth?
4 usable balls per side. 6 decoration.
Maybe it is a calibration thing. I have been playing the game daily for the past week and leaving the game powered up for long periods of time (12 plus hours) and I haven’t experienced any cycling of balls during attract mode.
The only thing I can think of, cycling occurs when a connector on a board becomes unplugged and then reseated.
First time I ever got the game I had unplugged all the connectors to reseat them as the game had sat for a number of years un-used. I had cycling then. Then it stopped.
I had removed the head of the game to get it into the basement. When reconnected, I had a cycling when I first powered on. None since.
Could be just coincidence.
