I’m working on a Stern Magic for a friend. It boots up fine and the voltages are fine but I have no displays. I checked the first display and have 175 volts at TP2 and 5 volts at TP1. I checked PinWiki and it says it might be something in the blanking circuit.
I’m not good at working on a board in the game but I have a pretty good bench tester for 12 and 5 volts. Can I check the blanking circuit on the bench without having the displays connected?
