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 5800

I can help you solve this problem. However you must describe to me which fuse you have replaced. Is it the fuse on the power line or is it a fuse in the speaker line (which I highly doubt). usually this type of amplifier uses two technologies. One is transistors the second is integrated chips. This is in regard to the output stages. I assumed you speaker cables shorted each other while the volume was set at a high level with music playing. Anyway if you are willing I am able to help.

If DIGITAL sign on the display blink, it mean the DSP board is defective. probably the DSP itself

Well,i can tell you are not very focus,cause you posted Denon AVR-2807 with Bose AC 15 problem,but under your details,you put down AVR-5807!
First of all,it is so unfortunate that you are NOT able to gain and experience to true ability in sound for this wonderful receiver when you are using a dual tweeters speakers and expect to have good sound separation as a TWO WAY speakers(a tweeter and a midrange-for true high frequency and mid frequency sound separation.)
Secondly,you have defeated the audio configuration of the Denon AVR-2807,since all your speakers are control BY the Bose subwoofer.
Now,i could show you a way to hook this up,and it doesn't matter how you connect them, they are the "bicycle tires" installed with a "Porche"engine if you know what i mean.
If you want a good recommendation for your "beast",i will more than happy to show you the way!
Cheers,

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.

My denon receiver avr-4802, has a clicking sound when i always turn it on


Hello
you haven't specified about its working. Whether it works properly after the clicking or not. It is normal to all Hi-Power amps, there will be a click sound, catching speaker output relay. If the amp works properly, the click sound can neglected. But if amp cuts off after the click sound, there is something fault. It can be inside the amp or outside to connections to speaker. If it cliks and shuts off/stanby, protection circuit inside it has the fault and should be rectified. To look into that section, one must have through knoledge in electonics, and have experience in trouble shooting, because it is the most complicated circuit part of that system. Ok.

I just bought a Denon AVR 1611. All inputs are HDMI (Cable TV, Blu-Ray) and the monitor output to the TV is HDMI. ainly I listen to the audio out of my TV and occassional on my surround sound. I would...


avatar7.jpgcurt, I bought this Denon AVR 1611 and I have HD cable. If you have cable you can set it up two ways. First way (the way I have it) is to get a switch box with 2 HDMI
out (mine has 4 inputs and 2 outputs) and maybe 2-4 inputs. Put the cable from the wall in one of the switch box inputs. Now hears the cool thing. Put 1 of the outputs from the switch box to the Sat/Cable input on the 1611 then put the another output to your tvs HDMI input. This allows you to switch from the tv only output or the 1611 surround output without touching the switch box. The other way is to buy a converter from HDMI to VGA. The only thing here is that you would have to setup your sound through Aux in the front of the 1611..........Johnmoondancer@hotmail.com

I have a Denon AVR 1509 and when I turn the power on it flashed green but after about 2 seconds it cuts out and and then flashed red every 0.5 seconds.


Usually its the power output stage . You can visibly check it if theres a burned resistor on the output amplifier. On the base of the Power output transistor if the voltage is the same as the collector pin it will indicate a shorted power amplifier circuit.

The left side main output won't put out any sound on my Denon AVR-900.


connect your right speaker cable to the left output, if the sound comes out then the problem is on the left speaker ( the cable or the speaker itself ), but if still no sound, then the problem is on the power output of the unit, need to repair them

Denon AVR-1403 connected to DVD can hear music but no dialougue!!


Check the center channel speaker and the surround sound audio settings. If you do not have a center speaker, it needs to be set to off on the receiver.

No sound from Sub.... from my Denon AVR-2700, not AVR-3300, Yeah its old!


if the subwoofer is on in the reciecer settings then maybe the amp is not getting the signal or the amp is not amplifying
try unplugging the output of the sub then turn off the reciever for a min. then turn it on wait , then plug the sub in
if that don't work then test the sub output with a stereo that has a audio input
also test the subwoofer with a audio output to it( only a positive and a negitive wire for sub)

No sound


1. check if the amp is in PROTECTION mode (might be a bad speaker or shorted output)
2. check the 'MUTE' switch
3. try to use the FM/AM mode to isolate an input source. If there is sound then check input source.
4. ...still no sound have a techinician check it.

AVR-1603 - no Sound exept over Headphones is a weak signal


First check the outputs at the output fets/transistors for any DC voltage. Reference your voltmeter to the speaker - terminal. If there is ANY DC offset, the amp is shutting down the outputs to protect your speakers from DC. Is the power supply + and - 47 volts? If only one supply is there That is your problem because the supplies should be symmetrical. Also look for any wiring problems from the amp to your speakers... any shorts? Try disconnecting all your speakers to totally eliminate any speaker problem and see if the relays still click. You should hear only ONE click when you first turn the amp on (delay of about 2-5 seconds). If they keep clicking the amp outputs are next. Also, is there any indication on the front panel of what is failing?
