I have a problem and could use some help. The other day I came I to the room and the machine was making a never ending audible tone and all the numbers on the pin scores were blank. I turned it of and back on and it booted up fine. When I hit the start button the game started but the targets didn't reset and the ball didn't shoot out but the flippers work. The machine will register a score if you hit the ball on a bumper. Anybody have any idea??
