I bought a Freddy Nightmare on Elm Street last weekend and noticed some strange behavior once I got it home. A number of the targets aren't triggering, among a few other things. I've included a video below for reference. What I've noticed thus far that's not working: target next to the boiler, targets under Freddy's head, return lane, kick save, glove flipper works sparingly (1/10 of the time or less).

Anyone have a recommendation on where to start? Any feedback or guidance is appreciated.

Thank you both very much! Your suggestions sent me in the right direction. A connector was unplugged next to the switch diode board. See the below photo, to the right. Popped it back in and all was well. The game is back to full functionality, maybe save for the kick save. Will re-post on that later after a closer look.

Ironically, I'm guessing this was accidentally unplugged or kicked loose by the seller prior to me purchasing. He replace a nearby flipper coil right before I took it home.
