Hey all, I was just playing a game and was scoring well when all of a sudden during multiball, all balls in the trough were being kicked into the shooter lane as fast as possible (no ball save at the time). There were no balls stuck anywhere and the ball eventually just ended for some reason.
I ran some tests and found a properly working shooter lane switch but all optos in the trough failed testing as staying open. I re-sat all connectors at the opto board A-22019 and looked for any loose or broken wires but couldn’t find anything. I did note that during testing the red LED does not illuminate like it does on other boards under the playfield.
Anyone have next steps for ruling out the failure or fix? Not looking to just buy another board for $150 to find out it works fine just yet.
