I have a 1996 Power Macintosh that does nothing when I flip it on. I pulled the PSU board and it's dead silent. No sound, and a trickle of 2 volts on one 5 volt rail.
I pulled the filter caps and they tested out fine. I see 115 volts AC on one lead for each cap, but nothing on the otehr side.
I can keep pulling and testing caps, but I suspect it might be something else. Any tips / refernences for these boards?
