I have a Golden tee complete in a Midway cabinet. It recently stopped working. When I turn it on I can hear the monitor energize but that’s it. No lights on power supply or boards. When I check voltage at power supply I get 70v on AC L and 60v on AC N. The 5v output is showing nothing. What could cause the low voltage at the power supply. Could the isolation transformer be bad. There is a switch on top to turn game on and off. Any ideas on where to start looking to fix this. I’d love to be able to play while stuck at home. Thanks.
