Check again d901 in diode mode for short (I do not remember by heart the internal schematics of the bridge rectifiers, so I test each pin to each other pins, then switch the probes and again).
You can use IPA to find the hot component(s) - drop IPA on the component and see how fast evaporates.
Thermal print labels also can be used - cover area with a label and see where it will get black.
This power rail doesn't have too many common points to ground - q502, d516, q501, q434+q436... all other possible paths include too many components that have to be shorted. So try injecting voltage again and check that components if they are getting hot.

what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!
