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 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...

HELP

SOURCE: Denon AVR-1508

If your amp looks like it's going to work as normal (ie the front display lights up as it should etc), but then the amp goes into protection mode when the anti-thud circuit times out, then I know what's likely to be wrong.

It's one of the power amplifier channels which has gone faulty.

I just found this out after having this problem with my AVR-1906.

I took the amp apart and de-soldered the suspected channel power transistors (centre channel in my case).....and hey-presto! it fired up as normal (obviously the centre channel would be out of service).

I have ordered the replacement transistors from Farnell (UK) at a miserly cost of around £2-£3 each.

Just waiting for them to arrive.

An alternative is, if you don't use all your channels, take the transistors from a known working but not needed channel and swap them over with the duff ones.

Hope thats of use!

SOURCE: connection problem with HDMI cables on Denon AVR-589

Hi dmsgolfer22,

If your Time Warner Cable box is old enough that it has a DVI output it may have HDCP (copy protection issues) with the receiver. If you are having to use a DVI to HDMI adapter to connect to your receiver (output from Cable Box to input on Receiver) then it's very likely your cable box may have may not output the signal because it detects the HDMI repeater in the receiver.

The two best options to correct this are:
1. Connect the DVI to HDMI cable directly to the input on the TV, you lose the convenience of the video switching in the TV, but it will solve the problem. Then connect the digital audio output from your cable box to the receiver, although you've probably already done this.

2. Contact your cable provider and check into the possibility of them swapping out your cable box for a newer model that would have an HDMI output. This would be the best option since the HDMI output on the cable box would give you both the Digital Audio and Video through a single HDMI cable.

Let me know how it works out for your, or if you have any questions.

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.

Purchased denon AVR-689 in 2009 worked fine until the other night while watching tv the receiver started turning itself on and off


Phantom OFF may be a self-protection mechanism. Phantom ON would be a poltergeist or other remote control command from somewhere.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Subwoofer will not produce sound. Connections are correct. I do hear a hum or a crackel as I pull the connection on and off. AVR-689 model


In order to ensure output to your subwoofer: make sure the subwoofer is connected to the subwoofer out of your amplifier and make sure that your amplifier/receiver is set to output multi channel sound

I have lost video on my tv - connected via hdmi to denon avr-689 receiver.


Had a similar issue, replaced the receiver three times in first month. The fourth time it had to go back to Denon. They returned it saying no fault. Also replaced HDMI cables etc...real head scratcher. Turns out it was the tv. The system can get discombobulated if the receiver, tv and source are not sequenced correctly. This is due to the HDMI protocol, Power up sequence should be receiver, source tv. Once video is lost it has to be rest. With system powered up and tv displaying no signal, remove HDMI cable at tv. Turn off tv at outlet and leave of for 2 minutes (this rests HDMI port, important to leave off long enough!.). Turn tv on and reconnect HDMi...all should be good. Poor Denon, I blamed them when it was my Sony Braiva all along....bad Sony

Recvr produces no sound from speakers,is there a factory reset sequence i can do to get rid of all settings i have made?


Maybe there's a simpler fix. Examine every indicator on the front and understand what they mean.

Un-select anything to do with Tape or Muting. Disconnect the headphones. Properly select the input. DE-select EXT IN.

Denon AVR-1100 receiver "PROTECT" mode


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?
