Just picked up this machine. It turns on and will start a game but won't kick up balls and flippers do not work. The Dmd is not working but have tested voltages and it needs a newer power control board to take of that issue. I have read on pinwiki and was thinking that it may be a locked on coil and the CPU locks out flippers and coils to keep from doing more damage. Not sure what to do next. THanks for the tips
