I think those 'Capacitors' are actually resistors? At least that is what it appears you have pointed to.
The symptom you have sounds like a classic symptom of short on the DC output, most likely on the 24vdc, I would disconnect the 24v connections on the RH side of the PS one at a time and see if it stays on.
The last one I had, was a shorted 5v regulator (24vdc fed) on the video board.
It can also be limits switch etc shorted.
