SOURCE: Denon AVR-810 going into PROTECTION mode

It sounds like there is a problem with the differential circuit. The bias I am not sure about, as every unit is different. You should get the service manual to be sure or call Denon and see if they can give you an idea. Good Luck

SOURCE: Denon DRA397 Panel lock on.


Denon has for some reason removed this function from their user manuals. However The manual does show how to do a manual reset of the unit. This may correct the issue.

With the Amp OFF but plugged in, press and hold the speaker A and B buttons and while still holding them press the POWER button. Continue to hold the speaker buttons for another second or so. The display should all light up and flash at 1-second intervals. If not flashing, try again.

This should reset the unit back to factory state with the front panel lock disabled.

SOURCE: protection error in denon avr-3000

its the main amp in your unit. Depending on the construction the main amp can be an IC (Integrated Circuit) or discrete components. Anyway, the protective relay protects your speakers from being destroyed. When a main amp breaks down it normally outputs DC voltage. DC voltage is not good at all for a speaker.

You need to replace all the defective components in your unit before the unit will be up running again.

This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

SOURCE: subwoofer works in test mode on denon avr 790. but

I had the same problem. The system from the factory does not ship confgured for continuous subwoofer output. To fix this, do the following:

1. Enter the system menu.
2. Go to "Speaker Setup"
3. Select "Bass Setting"
4. Change the setting from "LFE" to "LFE+Main"

That should do it... You can also see this information in the "Bass Settings" section of the product manual on page 26.

Cannot disable panel lock

This may not work, as it appears to be for a different model, but it states:

How do I unlock the panel on my DRA-397?

Power the unit off using the On/Off button. (not the larger On/Standby button) While the unit is powered off, press and hold the "Speaker B" and "Mode" buttons. Without releasing those buttons, power the unit back on. This will unlock the panel.

Front panel is locked and don't know how to unlock it.

1) turn off the main power button (not the big LED stanby button)
2) press and hold "input mode" and "speakers" button simultaneously
3) press and hold the main power button for seconds, until display flashes.
4) release all those buttons. The AVR is already reset to factory mode.

Unit worked flawlessly 1 hour ago

Hi Ernietex,

Dont blame your wife.

Your receiver is basically going into protect mode.

The Denon AVRs contains a microcomputer for signal processing and control functions. In an unlikely event, it may cause it to lock up. Unplug the power cord from the wall outlet, wait for 10 to15 seconds and then plug it back again.

But, before you do than, please also check your speaker cabling again. Make sure that all of them are seated properly, none is touching each other or the body of receiver. Take out all the wire and put them back again if necessary..
Some times even a little tiny frayed wire touching the receiver could trigger the protect mode. Be careful, since protect mode is sometimes not fast enough and it could blown a few trasistors in the power circuit.
Just check your speaker as well....whether they play all right thru another receiver or amplifier. its posiible they might be shorting inside. A little frayed wire could also trigger the protect circuit in your receiver.
I hope this should solve your problem.

If you still can’t resolve the issue yourself, try resetting the AV receiver/AV amplifier before going on to opening the Receiver.

Hope you can sort out your problem with the above trouble shooting. Let me know if I can guide you further.
Best of luck. Thanks for using FixYa!

Help required for dumbo on Amps Denon AVR 2808CI

Your unit was probably damaged in shipping. Denon is a nice unit! Do you hear any clicks when you hit the power button??? You should hear two relay clicks. You should hear the power relay click at power on and 3 to 5 seconds later you should hear the speaker protection relay click if your audio amp section is ok. If you hear both relays click then your display circuit is at fault. Open the unit and look for breaks on the front pcb (behind the display) and on the main board in the power section ( where the fuses are ).
Good Luck!
