I happen to have mine apart right now haha

Mine has no power either, have a feeling it was a power surge during a lightning storm. Can't find any obvious blown pieces, and the 250v fuse is testing good I think. This is out of my realm of expertise though.

Have a VERY close look at R1262 (close to C3 - one of the big primary filter capacitors). Mine was blown, but it was only just visible. Am fairly sure it is a 102 (1Kohm) resistor, so easy to replace. That got me back from 0v output to about 30V. Now trying to figure out what else is damaged…
