Hi, I'm Nathan.
Sorry to hear that you're having trouble with this but I'll do my best to help you.

Expert:  Nathan replied 10 months ago.

This is a protection circuit kicking in to protect the receiver from damage.

This could be caused by a short in one of the speakers or components, thermal fault, or an internal defect in the amp itself.

You can try a few fixes yourself. To begin, with the receiver powered off, disconnect all speakers and components. Try to turn it back on in Tuner (am/fm) mode and see if it will stay on. If it does, power off and reconnect 1 speaker, then power on to test again. Continue this process until you isolate the speaker or component causing the problem, or until everything operates normally.

Let me know the results, or lack thereof, and I’ll advise further if needed.

Yes I'm here, please send only a single response and allow me time to receive and respond, multiple messages can get lost/delayed.

You can try the reset process (which you tried before) again with everything disconnected,

if still no change, that confirms a hardware fault, meaning a short in the power supply or amplifier section.

There is no quick fix or reset for that, it would require physical repairs to correct.

At that point your next step is to call yamaha support, as this unit is still under the 3 year factory warranty, you may reach them at(###) ###-#### and they will authorize repair at the closest shop.

Best regards, ***** ***** for the news,
