[Red to black]

Here is the PSU diagram attached, I can see that on this diagram a few possibilities for a dead machine.
This PSU uses high value resistors for start-up, R 1105,1106 both 1 Megohms in series are prime candidates to check.

A check on the series connected chain of 12K resistors, R 1103,4,8,10,17 and 1126 might also be worth while.

If you need the full manual then contact me via PM.
