Going back to the most basics, establish your 5v standby voltage, if absent your fault is in P.S.U. If this is present check for the pwr-on voltage from the main pcb, good luck with it!

tip
Its incorrect drive from the hybrid IC IC201 that blows the FET

Make sure to reflow the entire hybrid IC201.
Don't forget to reflow SMD's on IC201
.
Also open the 2 relays and clean contacts. They unclip quite easily
