I have fixed a bunch of issues on this machine and I have it almost 100% working save this one issue that has me stumped. I am fairly new to pinball repair in general, and have learned a lot on this game, just one final thing to fix that I am hoping to get some help with.
Fixed issues so far:
Replaced the DMD driver board and the DMD works
Found a wire pulled out in the back, fixed an issue with a column of switches being out.
Replaced the original opto board with a GLM board, solved ramp opto problem.
The ramp opto works just as it should now, and the LED's light up as they should on the opto board, and the ramp functions great in game.
The pitching opto is still not working though. I replaced the opto sensors, and confirmed light is coming out of the emitter (using an iPhone front camera). The opto board shows both LED's as on (as if the light is being sensed by the receiver) however it is like this when the receiver is not facing the emitter at all. Basically the board shows IR light is being sensed when no IR light should be getting sensed at all. Any thoughts?
