Problem:
5v measures .6v at board with no led lit, no blinking start buttons or screen image.
What's been done and checked:
All voltages on power brick test good
All voltages on ar-II test good with board disconnected, ar-II was rebuilt 4 months ago with Bob Roberts kit.
Board interconnect continuity checked and pins re-flowed
all new caps on boards
no wires grounding out on coin door or underneath control panel
My next guess other than something shorted on the board is something on the ar-II failed that wasn't replaced in the rebuild kit. Does Q1, the 5v volt linear voltage regulator fail often?
