I have an X's & O's Pinball and recently all of the "O"'s quit lighting up. It looks like the Aux Lamp Board runs those lights, but I am getting 5 volts. When I first turn it on some of the O's will light up, but they are dim and flicker. Then when you start a game, absolutely nothing. I also notice the volume of the machine is much softer when this happened, not sure if that's related. Any ideas?
