I'm working on a Tron with a power problem that I can't quite pin down. The problem started when I plugged it one night to find out the power plug itself had a short in it. None of the fuses in the game popped. I replaced the plug and checked out the supply and I am getting the 12 volts but I am getting between 2.5 and 3 volts on the 5 volt line with or without the boards connected.
I've tested with other power boards (some have the reset disabled) and they always have the low voltage. All of the boards test good in other games. I also swapped the filter assembly that has the diodes and caps from another Tron and still get the same low voltage. When I measure the voltages from the transformer itself, they are all there but measure about 1 volt higher than what is noted in the manual.
Any one have any suggestions on what to try next?
