The pin is in awesome shape, however, I have one minor issue with the Prison opto's. They don't always register during a game. They always work in test (rolling a ball) but sometimes (less than 20%) of the time a hit to the doors will not trigger the opto. I replaced the opto's with new ones and re-seated all the board connectors (back-box and opto board). I tried re-aligning them. The game does have a cliffy carbon protector around the prison magnet so is it possible that the ball deflects just high enough to not trigger the opto?
Usually, seems worse at the start of a game - but that might just be me imagining things. This game is hard enough as it is so hopefully someone can help me figure this out. Any ideas? Could it be an intermittent issue with the opto board? Anyone with a similar issue in the past?
Thanks everyone and Happy Zombie hunting.
