The upper playfield lights on my Earthshaker are not working and apparently haven't worked since I've had it. I thought they were just burned lamps that weren't replaced due to how hard they are to get to. But I just installed new plastics and ramps and put in LEDs while I was at it. The upper playfield still does not light except for flashers. (lamps in photo) In test mode, the upper playfield does not light while the lower playfield does. Any ideas?
