J107 doesn't even go to the Fliptronics II board.
I would check the flashers, make sure the legs are not touching each other and creating a short. I had this happen on my IJ, when lowering the playfield a flasher had the legs pressed close enough together that it created a short.
Maybe the knocker coil if that was overlooked.
