I have on older power edge 1400sc which I was trying to place in a lab. I wanted to add an additional cpu, and released I also needed a corresponding VRM (voltage regulator module) I got one from eBay the main numbers matched 05S2020A-4 the lower DET numbers did not match. The look exactly the same - capacitor colors slightyl different
I added the new vrm and cpu but that stopped the video/display from showing - I removed it - the display came back. I switched the existing vrm to the other bay and the video stopped displaying - and now no matter what I do the video will not display.
I've verified the monitor is working.
I've spent allot of time and money on this (by now could have got a much better machine but this became a growing project)
Can anyone tell me what I can do to get to see my screen again? I'm really hoping I did not toast something.
Thanks
Bob
