Got about 30 plays on my game and the bar door stopped working. I lifted the playfield and found this. Looks like it’s missing the set screws? How many should be installed? I checked everywhere inside the cabinet and found no loose screws. I’m guessing the set screws were forgot at the factory and it worked a bit because of the little amount of friction that was there.
What size and type of screw do I need? Would someone mind posting a picture of theirs?
