1) Speakers not playing audio at all. Not even when you turn up or down the volume.
2) Drop target guarding the upper left playfield not functioning.
3) The lift at the back of the playfield is not working properly when Dorothy is captured. At the very least, it's still registering that Dorothy is captured.
4) The only lights functioning are the ones in the upper center of the playfield. All of the other LED's on the left, right, and lower center playfield are turned completely off with no interaction whatsoever. Any advice on what to do with all of these issues?
