Can't take on any more myself at the moment, but one thing I've noticed with my Indigo1 power supplies is that occasionally some of the beefy diodes in the rectifier circuits like to blow. Should be able to find that out quite quickly with a meter if so.

So I am giving another shot to fix the R4000 Indigo PSU. If someone has one, I need confirmation of 2 parts in the main board of the PSU. QI03 and QI04. Two Transistor. I thinkg one of them is bad on my unit. Behind the 2 Big capacitors 200uf 200v.
