Question about Denon Audio & Video Receivers

Denon Receiver flashed PROTECTION and stopped working after plastic smell

My Denon AVR-1200 Receiver stopped working after I determined that one of the speaker wires were crossed (they wires had been pulled accidentally from the speaker and were touching together). A burnt plastic smell appeared and the receiver stopped working, it just flashed PROTECTION and was rather overheated.  I tried unplugging everything and cooling it down and tried reseting it, but nothing.  I looked for blown caps or other obvious visual problems but nothing.  Is it something that is easily fixable or worth getting fixed?  This is the first problem in 11 years, it worked flawlessly throghout.

Denon avr-1506 will turn on then flash red and turn off... how do i make it stop or fix it??

In most AV receivers if the standby light flashes after turning on and you don't hear the regular click of the relay engaging after 4 seconds, indicates an output short or amplifier failure. The protection circuit prevents any further damage by not turning on system.
You will need professional help to fix this problem because even to a electronic enthusiast the construction of a typical AVR is not service friendly.

I have an avr 4800, and eveytime I raise the volume to -21 or higher it goes into protection mode. can you help? my zipcode is 60184

I'd treat this symptom as "DISPLAY not lit and power indicator is flashing rapidly." under Troubleshooting on Page 60.

and I'd evaluate the speaker load you're presenting to make sure it's effectively higher than 6-0hms per speaker channel.

Power button turns green, flashes and then turns red and flashes.

While working it stops and flashes red approximately 2 seconds interval

Protection circuit is activated depending on the temperature of the surroundings

Switch off the power supply and power on after the temperature have reduced.

While working it stops and flashes red approximately 0.5 seconds interval

1.Using speakers having less impedance than the specified.
2.If speaker core wire touch each other Protection circuit is activated

Even applying power red flashes 0.5 seconds interval

Amplifier circuit has failed

Switch off the power and contact denon service centre

Thank You

AVR-1802 5.1 Channels Receiver: My Denon AVR-1802 LED is flashing rapidly. I have...

replace all the electrolytic capacitors in the power supply. i had the exact same problem with mine and once i replaced the capacitors it powered up and stayed on and worked perfect.
these capacitors tend to fail as they're of poor quality.
this fault is very common on denon receivers, especially the later models.

hope this helps?

Power shut down

It is a protection because of a power supply malfunction or bad channel (most likely). Repair it at

Denon avr-5600 protection circuit.

My AVR 5600 has worked flawlessly for nearly 9 years!

Suddenly, when trying to play music (DVD or CD) through my LS32's (JBLPro), once I achieve higher volume, the receiver cuts off.... Using a Symetrex mixer, NO OVERLOAD light on the Denon, it simply cuts off!

Re-cut all the wire connectors... TV movies (5.1) work great at normal listening volumes.... but tonight, when cranking up music, the receiver simply cut off. Blinking light...

AVR 810 Denon Receiver Sub Woofer Hookup?

Denon AVR-810 was a quite out-dated model. I had owned since 1992. It shown 'Protection' on the screen for 2 months ago and not yet been fixed. Better to replace a modern one or repair it at a reasonable costs.
