I had some weird faults with the large connector on the opto board under the playfield with various things, I’ve had to re punch the cables down a few times to fix. Think it effected the gumball amongst other things.
Also the ribbon cables have given me weird faults.
If the problem was only with the trough proximity and the led was seeing the steel ball then turning off when ceramic ball was there and the matrix wasn’t seeing this then I would say change u2 4N35 optocoupler as this fixed mine last week.
But if it’s the other proximity sensor as well then it’s not what I said above I wouldn’t have thought.
