Question about Denon AVR-1911 Receiver

1 Answer

While watching satellite tv, receiver will work fine for a good while (an hour or more), then you begin hearing what sounds like static in the right front channel, followed shortly after by the receiver shutting itself off. You can turn it back on immediately, and it will work fine. Any ideas?

Sometimes equipment gets too hot and starts glitching. Try an improve cooling and air circulation. Often standing the thing on one end so it's tall will help keep it cool. See if it goes for longer with better cooling.

SOURCE: avr 3806 power shuts off when volume turned up

Hello david 420

It looks like your receiver's high-speed protection circuit is being activated. It is definitively not a fuse. When a fuse pops, you have to physically replace it. When the protection circuit is activated, the speaker output is cut off and the power supply indicator flashes. There are a few reasons why this happens:

1.- Your speaker wire connections are loose. Whether they are banana plugs or bare wire ends, make sure the speaker terminals on the back of your receiver are tight using clockwise turning.
2.- Verify that your speakers have an impedance between 6 and 16 ohms. Your receiver was designed to work with that impedance range. Any impedance lower than 6 ohms will activate the protection circuitry.
3.- The receiver is used at high volume levels over a long period, which results in an
extreme temperature rise. Improving the ventilation conditions around the unit might help alleviate the problem.

If after complying with these suggestions, problem is still present, you might need to have the unit checked by a professional for possible circuit failure.
Hope this helps. Let me know.

SOURCE: AVR-3300 Static and Sound Loss

The Denon Curse.......the connectors that the input boards ( up and down if your receiver is in the normal position ), plug into one of the 2 main boards on the bottom. These connectors are suspect and need to be cleaned and re-soldered. Same with the board that runs from the input side of the unit ( right behind the front panel, running across the unit ) to the amplifier board. Denons were HORRIBLE for bad connections with these. This is an involved repair requiring the entire thing to be pulled apart. It is not an afternoon job for a do-it-yourselfer, take it to an authorized Denon repair shop, as I GUARANTEE that they have seen this problem many times for all models from 2000-01-02-03. Good luck..... Rob

SOURCE: Denon AVR-3802 Front Left and Centre channel not working right

I work at an authorized Denon service center and have repaired lots of Denon receivers including this model. So bare with me, and trust that I really do know what I am talking about.

The first thing you need to do is find out if those two speakers may be at fault. You can do it very easy by disconnecting them and connect two of the known good speakers into the channels that the bad sound is coming from and then connect the suspected bad speakers in where those good speakers were connected to.

If the same speakers still sound bad, you know that you have a couple of bad speakers. I think that it is likely that the speakers are OK, but it is a good idea to make sure.

If the sound from the suspected bad channels is now still bad with the two good speakers, you have an internal amplifier problem or you have a problem on the digital board.

For your sake, I hope it is the amplifier that is giving you this problem, if it is, that can be fixed by a good audio technician.

If the problem is the digital board, you may be in for some real headaches. Not that many audio techs are very good at troubleshooting a digital board, its not their fault, it is just a very difficult job.

In either case, it will need to be looked at by a qualified technician.

I hesitate to tell you this, but the problem sounds like a digital board problem. In some rare cases, a technician with excellent soldering skills can reflow a couple if the memory IC's on the digital board and restore proper operation. If the technician is top notch and isolates the problem to a specific IC on the digital board, they can replace that IC and you are good to go.
But in most cases, the technician will not even bother trying to troubleshoot the digital board because it can take hours of troubleshooting, and just order the board if it is available. Most of them are available from Denon, but they are very expensive. Normally the part alone is $200 to $300 and I have seen many times where it takes months to get it.

You can also send it directly to Denon's factory service center and that will get your unit back much quicker. They have direct access to the boards, where-as the authorized service center must order it thru one of the Denon parts distributors and they do not always have them in stock. so you end up waiting for a long time.

If you need to send it to the Denon factory service, let me know and I will email you a return authorization form, this must be faxed or emialed to Denon with the proper information and then they will fax or email it back to you with the RA number which must be written on the outside of the box before shipping it to them.

I hope that this information wasn't to overwhelming, but if you found it helpful a good rating would really be appreciated. It helps to keep the experts on FixYa motivated and willing to answer the questions people have even it the answer is not very good news.
I received an "inappropriate" rating from somebody who just wasn't happy with the truth, and most people never even bother to rate our answers. But that's another whole subject.

let me know if you need more help.

Hi,
I have same DD 5.1 tiny "bursts" problem with satellite HD channel. It is probably problem with Crystal DSP (German site): http://forum.digitalfernsehen.de/forum/showthread.php?t=89328&page=3
"Denon bietet Lösung für EX-Flag-Problem bei den Modellen AVR-1602 und AVR-1802 an

07.08.2002(cr)
Dass die Denon AV-Receiver AVR-1802 und AVR-1602 die mit einem DD 5.1EX-Flag versehenen Tonspur von "Atlantis" und dem "Herrn der Ringe"nicht abspielen können, ist ein spezifisches Problem von einerbestimmten Revision des in diesen Geräten verbauten Crystal DSPs.Dieser Chip wird u.a auch in einigen Kenwood- und Onkyo-Modelleneingesetzt.Da es von diesem Crystal Chip unterschiedliche verbauteRevisionen gibt, von denen aber nur eine bestimmte betroffen ist,werden die beiden Filme auf dem größten Teil der verkauften AV-Receiverohne Schwierigkeiten laufen.
Denon bietet nun für alle betroffenen Kunden, die ihr Gerät beimdeutschen autorisierten Fachhandel erworben haben, eine kostenloseModifikation an. Das Gerät muss beim entsprechenden Fachhändlerabgegeben werden mit dem Hinweis auf das Herr-der-Ringe- bzw.Atlantis-Problem.
Momentan steht nur eine begrenzte Anzahl an DSPs zur Verfügung - Denonhofft, dass kurzfristig ein größeres Kontingent eintrifft.
Denon bittet daher die Kunden freundlich um Verständnis, dass nichtalle betroffenen Geräte auf einmal und sofort umgerüstet werden können."

This is a site where you can download a manual. I'm not familiar with Denen however, you should be able to go out of satellite receiver(HDMI) to your receiver input(tv/sat) then to your HDMI input on tv. Your receiver might show video and sound through another port of receivers options, ie; video 1, video 2, etc. Check all putput options for your picture and sound. Hope this helps.

Projection TV. DVD works. Cable often seems, "untuned". Static & un-fine-tuned sound of channel with black screen. Then, later, it will come on just fine. Sometimes, will go back to untuned status.


I would suspect your cable box first. I would unplug the power cable from your cable box and wait 60 seconds. Plug it back in and try to watch cable tv. I would also make sure the coaxial cable going from the wall to your cable box is connected properly. I would also make sure the cable going from the cable box to the tv is connected properly. Test your tv and see if it works correctly when you watch cable. If this fixes the issue you are good to go.
  • If this makes no difference use a set of new cables if you have them.
  • If this does not work then call your cable company. They may have to replace your cable box.

Make sure that the volume is not muted or too low on the TV...the TV volume output to your receiver will be performing the function of a pre-amp to your receiver. Then select the appropriate input on the receiver that you have the TV audio connected to.

I suggest you check the satellite receiver first, you can use the component or HDMI cable for the satellite receiver to check it. If still no sound, the TV main board is defective.

OK. For all you regular Joe's like me here's the fix--plain and simple! I have Dish Networks HD receiver, an LG Home Theater System (LHB953) and an LG HD Television - although I suspect this applies for most LG TV-to-LG Audio Systems used in combination with a HD TV). My problem lied within the LG to LG setting known as SIMPLINK which tries to "auto-configure" everything between LG to LG devices.

Do this to make your HD TV (using Dish/DirecTV) play it's HD video display from the satellite provider but play the audio over the LG surround sound speakers:

1. Plug a HDMI cable from your satelite receiver's set-top-box to your HD TV. This will carry your HD "video" ONLY. Click "Input" on the TV remote until the HD video signal shows your desired TV channel from your satellite provider.

2. Plug an HD Optical cable (the one with the red laser) from your LG HTS (Home Theater System) to your satellite box. This will carry your HD "audio" ONLY.

3. This is the magic everyone seems to be overlooking. On the LG TV remote, go into the menu options and disable SIMPLINK by setting SIMPLINK=OFF. This feature allows the video and audio signals to be split over 2 different ports: HD video goes over the HDMI cable and the audio to go over the HD Optical cable.

Hope this helps!

If you still can see the DirecTV guide and menu, the problem could be on your satellite receiver and not the TV. Unplug your receiver and plug it back.
If the rebooting did not work, I would suggest to swap the satellites receivers and see if it works.
Good Luck.
