When I power my Denon AVR-3311ci on, it only comes on for a second then shuts off completely. No blinking red light and nothing on the display. I can hear a relay on the power board clicking. Any ideas?...


There's an electrical problem! The unit shuts off to protect itself. the relay sound is normal and is part of the power supply - good quality amps have them. I suggest taking it to your local repair shop.

Greetings
have you checked the speaker cables ?
please do
Usually the Denon system has a problem with power regulators
if u have any knowledge in electronics i can guide u to repair it
if not .. u have to send it to service.

check for fuses if blown
power regulators mostly are damaged
and or power output transistor damaged
Good luck From Audio-adviser.com

Denon avr2312ci shuts off and blinks red


Yes that is why. The receiver is protecting itself from an un-stable load impedance which causes current/voltage spikes through the final amplifier components and proportionally through the input where the protection relay is (click),. Do not continue using the amp until you have repaired or replaced the blown speakers. A rule of thumb is to maintain 8 ohms on each speaker wire plugged into the amp. Keep that in mind or eventually you will damage it.

Denon AVR-1804 makes a metallic clicking sound and no sound from the speakers.


Most likely you have a faulty power supply or one of the other boards is drawing too much current causing the power relays to click out. Not an easy fix I'm afraid.

Denon AVR 789 no display


Time to send back to Denon (seriously). Hopefully you have a warranty on your product (I bought mine at Fry's and it took a few months for the warranty work to be performed). Good luck!

Reseat all audio connectors sometimes they get dirty. Do you have surge protection? Do any other audio functions work? Clean your remote change the batteries the mute may be stuck. I vote for the battries being weak and the remote will not clearly send all signals.

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!

Denon DRA-25/25L Stereo Receiver. On power up the display lights but no sound is produced by the unit. When working normally a click (relay?) is heard about 5secs after power up and normal speaker output...


Without looking at the schematics for this particular model, I'd surmise that the click is indeed a speaker protection relay. Generally this is fed by a number of different sense circuits that watch for power amp issues and/or excess speaker current and/or power supply output stability. Although the relays do indeed fail at times, generally it is not the relay that is at fault. If you have a scope and a schematic, you can check the various circuits that feed the relay for the exact cause. If not, you can do some experiments that might help deduce the problem: e.g. do headphones work when speakers do not, does the relay click on when no speakers are connected (or selected), etc. In my experience, it is most often the output transistor(s) in the power amp. But not always ;-)
