Jurassic Park Data East display went blank. Voltages at the DMD are as follows;
Pin 1 (-110) -111.5
Pin 2 (-98) -98
Pin 3
Pin 4
Pin 5
Pin 6 (+5) +4.9
Pin 7 (+12) 0
Pin 8 (+68) +68.5
I have no +12V on the DMD board and at the PS board. Swapped my DMD and it works fine, game sound, lights etc work fine. I know it's the 12 V portion of the power supply. I have inspected the PS board closely but didn't find anything obvious, see pics. What do I check next?
I have gone through the past threads but found nothing specific to +12 volts missing.
