Did you have any luck with this? I have a Mac Pro 4,1 (single CPU) that is exhibiting the same symptoms. It was on 2 days ago, now no power on at all.

Hi Max Entropy! Thanks for the quick and detailed reply. (I'll stick to replying to this thread, instead of starting new answers...)
 
I, too, have a second working machine, but I've yet to start the process of swapping components. My hunch is the same as yours — a surge has damaged the power system on the backplane board. The diagnostic button shows 5V on the backplane board, but jumping the SYS_PWR jumpers has no effect, which is all the detail that the ''Apple technician guide'' goes into.
 
So, I don't have any questions right now, but I would be very interested to hear how your new power chip works out.
 
Thanks again.
