Help needed please. Was playing a game and the screen did this and the flippers stopped working. I turned it off and back on the the screen goes blank all the way now. I can start a game but the ball will not eject and flippers will not work. sounds work as should but random coils just start firing(not the flippers)????? If I eject a ball manually games seams to work but I still can't use the flippers. I can also get into test modes but can't test anything as I can't see the screen.
