Problems with my Denon AVR2313CI home theater receiver.
Here’s what happens: I bought this receiver about a year and a half ago. Randomly, it will suddenly go into protected mode and shut down. I had it plugged into a UPS. It has plenty of air space, overheating is not the issue.
My first thought was that it was a problem with the receiver. Long story, but its not the receiver – I purchased a brand new Denon receiver and tried it and got the same problem, random shut downs into protected mode.
So – I next suspected the UPS. I plugged the receiver directly into the wall – same problem. So then, I suspected the house power, because it was in a newly-remodeled room in my house (with new electrical). To see if that was it, I ran an extension cord (about 30’) from an older circuit.
Same problem. I now have the electricians at my house trying to figure it out. They are measuring the voltage – it does drop, but nothing spectacular (the UPS is rated to correct voltage drops down to 89 volts). We plugged the receiver back into the UPS, turned it on, and then pulled the UPS plug out of the wall. No problem – the UPS started beeping, but the Denon did not go into protected mode.
My question is, what could possibly be getting through the UPS to the receiver that would cause it to go into protected mode? I am completely stumped.
Any help is greatly appreciated.

Just to be sure I have this right.
Two receivers, and both show the same problem of going into protect mode. Both exhibit the same problem when connected directly to a newly wired room/wall socket and also when connected to an old circuit.
If that is correct then then it can only be either a problem with the loading on the amp (driving it to hard, incorrect speaker impedance, a whisker wire short at a speaker/lead etc) or an oddball issue with the incoming mains.
(I'm not so sure posting all your details on an open forum is a good idea tbh)

Yes, what speakers are you using, how are they hooked up, and how loud do you listen? This must be the problem area.
This happened to both receivers with _nothing_ (no speakers, no tv, nothing) plugged into them. It happened with them plugged into a UPS, it happened with them plugged directly into the wall outlet, it happened when I got an extension cord and took it down to a completely separate circuit across the house.
It seems to be something wrong with my house power, which ok, I can understand - but again, what about my house power could be getting across the UPS? Can't be high, because the UPS cuts that out, can't be low, because it is rated to support voltage drops down to 89 volts. So what is the protection seeing that is causing it to shut down?

Can you take one to another location to test it there ? It sounds a strange issue.
I'm not really familiar with UPS in practice. When the mains is present, is the output UPS derived or simply mains routed through the UPS ?

FWIW... there is an inexpensive device to measure home current including spikes of various electrical parameters .

The two most likely things I can think of is a cheap wall wart close by.
Check with a battery powered AM radio the signal from the offending wall wart will kill the tuned station when you walk into the room with it playing.
The other thing could be a mobile/cell phone located too close while it is charging. These poll the provider to check for text messages every so often and need about 6 feet clearance from audio equipment to stop them making noises come from the amplifier and in your case causing a false alarm in the power supply overload trip.
