So I picked up a buck Rogers cheap. The side bumpers don't seem to work except one which actually didn't work at first. The pop bumpers work but not the pop up targets. The sound just loudly buzzes with high pitch squeals which once actually sounded like laser fire. The fuses "look" good. Ideas what's going on? Multiple solenoids out or a board issue? Is there a sound board that's having issues?

Ah yes I see. So the drop targets don't reload to be knocked down. Any of them. And of course sound just howls like crazy
