I realized the opt 1 ( switch 33) isn't registering. The other 3 all work fine in test mode. In test mode it does not register. I cleaned the optos and the insert as well. Removed the board and tried to reorient it, and it didn't change anything. . The optos on the play field are all lit red and stay lit, and the opto board under the play field has four red leds all lit up. Does this mean the opto board has a bad component? Or can the receiver opto on the board be bad and still have the led light up .
I cannot get the red led on the board to go off no matter how I block it if that helps( for that one switch)
thanks
