Pioneer VSX-531 Receiver does not power on (HDMI light blinks)

crwdns2934249:0crwdne2934249:0:

Pioneer VSX-531 AV Receiver
5.1-channel receiver with 5x130 Watt, 4 HDMI ports, HDCP 2.2, MCACC automatic calibration, Advanced Sound Retriever, Bluetooth and USB
I have a digital copy of the user manual | Need a schematic or wiring diagram
Expert researcher / Novice electrical repair experience (I know enough not to be dangerous, and can fix most basic electronics given enough time)
Source: Found “Free” on OfferUp
Issue:
* Unit does not power up
* When plugged in, HDMI light flashes (indicating error state)
* No other lights illuminate, standby/on button doesn’t function
Error Diagnosis:
(Per user manual): The HDMI indicator blinks and the power does not turn on.
* The receiver may have a serious problem. Do not try switching the receiver on. Unplug the receiver from the wall and call a Pioneer authorized independent service company
* That’s helpful…?
Troubleshooting:
* Able to temporarily clear error by simultaneously pressing “Advanced Surround” and “Standby/on” for 5 seconds
** After doing so, unit clicked, initialized, something got hot & smoked for a second
** Unit went back into safety power off
** Back to HDMI flashing error state
What I’ve done:
* Isolated component that was getting hot (smoking): Resistor R14FL
* Uninstalled the MOSFET / heatsync daughter board (720-07995-000-0S) from the unit, this board contains the overheating resistor
* Resistor tests same ohm resistance (.34) as adjacent resistor on neighbor MOSFET
