I am getting intermittent issue where balls are kicked out into the chute during play, though this makes for a fun multi-ball game every game, it is getting out of control.
I pulled the opto boards out and tested the led emitters and receptors, then put them back in and tested them with the game on and no balls in. I would block the chute with a self designed cardboard and test the signal at the 7 switch opto board. These all checked out. I exhausted my know how, and I am suspecting the chips on the 7 switch opto board. At this point I see these boards being offered anywhere from $10 - $70.
Before I buy another switch board, I would like to see if anyone had similar experience and could provide some guidance.
The worst case would be a CPU issue or a main board issue, but the game works fine aside from the spontaneous multi ball issue.
Thanks in advance
