I have Flash Gordon with an S&T board. The board works correctly on the bench with -5v to TP4, 12V to J1 P10 and ground to TP1. Pressing the self test button on the bench plays all the voices and the 1 sound and then it reboots as it should.
When installed in the game it does nothing. TP4 measures -14.9V. Does this mean that VR2 is bad?
