Hey all, I searched the thread but could not find an answer to an issue we're having; GnR won't allow a song to start? When a song is qualified (screen says Start The Song), the four inserts below the scoop light up as expected, but then a few seconds later they go out except for the "song" insert. Then, when you shoot the scoop, the ball just ejects out? It's like the song mode is canceled? This will continue to repeat. Only other thing odd is occasionally we're getting auto plunges at the start of a ball. And I've noticed each time the pin boots it says "calibrating sensors" in the lower left, but maybe that's normal and I just never noticed it before? I checked the switch test and nothing is stuck on. Any suggestions? Thanks!
