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

Really appreciate any help that the forum can offer :-)

Hello sir i was wondering did you ever end up figuring out the pioneer reciever. I had mine over heat also going into protection mode. Same resistors went out and that channel the transistors were bad too. I replaced them all and then soldered it all back together and reset it and the protection still comes on. Im at my witts end. Any insight would be great i really thought i had it whooped. I was able to download a service manual off manuallibs or something and its for a vsx530 and had very similar boards and parts so ive been hsing it to check curcuits.

Hi - I had the same issue where the HDMI light flashes and the unit turns off. I tried a factory reset, and now it won’t turn on at all (makes the click sound when you press the power button and then the similar power down noise). Any ideas?
