Re: Dell P2210f no power

Hi,

as I found this thread googling around for the same problem and nobody seems to have documented a fix, here's mine:

I had the same dead power supply and found that one of the big SR520 diodes was shorted. All caps looked fine in my case as well.

It seems to be insanely difficult to come by new SR520 diodes. Due to incorrect data sheets online (essentially copied SB520 data sheets), I figured it was a 5A 20V diode when it seems that it is in fact 200V. So I ended up buying SB560 (5A, 60V) as a replacement....
