The "Official" Denon AVR-2808CI Owners Thread - Page 121

Yes, it was. If you haven't already, reset the microprocessor (p. 50 OM).

I tried that as well. A little background. I just moved and had Geek squad out here to mount my tv and set up my equipment. When they set up the AVR and speakers there is no sound. They suggested taking the receiver to a repair shop but there were no issues prior to the move. There seems to be no output from the receiver to the speakers.

Try blowing compressed air a few more times as well as resetting the microprocessor a couple of more times ... letting the AVR's front panel display flash at least 4-5 seconds before releasing the two buttons. If still no joy, the pop the top and see if there are any fuses blown that can be replaced. If you're not comfortable doing that, then the next step is repair. Check Denon's website for any authorized repair facility in your local area, although note the facility will likely charge $75 just to check it out and then likely another $150-$200 for repair depending on the issue.

Thanks. I will try it again. I located a repair facility if none of that works.

Anyone knows how to check the currect firmware version, where to get the latest firmware and how to update the firmware for the 2808?

The firmware version can be checked by pressing/holding the STATUS/RETURN buttons on the front panel while powering on the AVR. Once on, simply press the STATUS button which will cycle through the various bits of info to include the main versions number. To obtain the available firmware for a European model refer to the following link ....

Thanks. Do you also maybe know how to update the firmware? I know I need a USB/RS232 cable but what the actual procedure?

The firmware download files should include an instructional .pdf that explains the process. You can get additional information by reviewing the thread below, as well as the additional thread linked in that thread.

I am having a problem with my Denon AVR-2808CI receiver. There is no sound from the receiver. Even when I go into the Speaker Setup section and do a Test Tone for each speaker, there is no sound. I have reset the unit and still no sound from the receiver. Can someone please provide me some tips on troubleshooting this issue.

Try blowing a can of compressed air into the headphone jack, and or insert/remove a headphone plug into the headphone jack.

I'm having trouble assigning my iPod Dock (ASD-3N) to my AVR-988.

I used the menu picks (Menu -> Input Setup -> Assign). In this assign menu (3-1 Assign), I set: It looks like this works. The selection is renamed to VCR/iPod (or DVR/iPod, etc. depending on which port I'm assigning) on the VAVR-988 display. This all seems okay.

The problem is, I don't see a menu for the iPod. According to the Owner's Manual, I should now have a new menu option (Menu -> Input Setup -> iPod)
I'm not able to see the menu: 3-5 iPod.

The real problem is that when I select the assigned port (DVR/iPod), I don't get any video or sound when I've docked an iPod.
I don't have access to the internet radio either.

Here's what I've tried (in rough order)
- assigning to 3 different ports (VCR, DVR, HDP) with the corresponding cable changes
- swapped out the supplied iPod dock cable with 2 RCA, 1 S-video, 1 3.5mm stereo
- read the Owner's Manual
- searched this thread & other Denon threads in the Receivers, AMPs & Processors forums
- reset the microprocessor in AVR-988
(I know it worked because I had to rename my ports to Comcast, etc)
- looked through the very readable docs at: www.batpigworld.com
- called & talked to Denon Tech Support
- reset the iPod Dock (paperclip in small hole bottom front, suggested by Denon Tech Support)

I know all the hardware works (or worked at one time) because I've used the internet radio feature before.

Any clues? What should I try (or re-try)?

At a high level, should I be able to configure the port on the AVR-988 and then see the 3-5 iPod menu even without hooking up any cables?
Should I be looking at: AVR-988 menu issue, cable/connections, or the iPod Dock?

Thanks for any guidance/suggestions.

AFAIK, no assigning is necessary when using the default "VCR/ipod" input jacks. Has the firmware on the dock been updated? Are you inserting the 3.5mm control cable into the correct input?

Yes. VCR/iPod was the default after I did the microprocessort reset. After this reset, I still didn't see the 3-5 iPod menu. I think I read something about the AVR-988 using the control cable (3.5mm) connection to enable some settings. Does this point to a cable/connection error with the 3.5mm Dock Control port?

I was using the Dock Control port (that you highlighted in your pic), perhaps the connector wasn't fully inserted.

As far as the firmware goes, I've had the ASD-3N for a couple of years. I don't recall if I did the firmware setup when I had it working before (perhaps 2 years ago). Would the paperclip reset of the ASD-3N have reset the firmware back to factory settings?

I can try to upgrage the firmware. The instruction imply that setting up internet radio is needed first before doing the firmware upgrade. "2.a: If Internet Radio cannot be accessed, the check all network settings and connections."

I'm unable to get the Internet Radio working. Can I still do the firmware upgrade?

If there is nothing obvious, I can walk through the whole process again. I may have had a cabling error.

I'd walk through the process again, ensuring secure connections of all cables. It sounds like this is more of an issue with the ASD-3N than with the AVR. If you cannot get internet radio to work from the dock, then it's unlikely a firmware update is possible. Try resetting the router/modem in which the docking station is connected.

Thanks for the suggestions jdsmoothie.

I tried eveything again from scratch including: reseting the microprocessor, reseting the doc (via paperclip), restarting the modem/router. I still see the same symptoms.

One thing I did notice has to do with the Ethernet connector (RJ45) on the iPod Doc (ASD-3N). The connector has green & amber LEDs. On most network gear, these LEDs are used to indicate connectivity & activity. No matter what I do, I don't see these LEDs lighted at any point in the testing process. This is consisent with no Internet radio function. I know the CAT5 cable is active because it works when I remove it from the ASD-3N and plug it into my PC.

Should I expect the any of the Ethernet LEDs on the ASD-3N to turn on if I plug in an active CAT5 cable?

Seems like a possible ASD-3N problem. I think my next steps are: Any other ideas/options?

Try pressing the A/B speaker button in front of the receiver, might solve the problem.
I had a Denon2808 and didnt get any sound until I found out that I had to press that button, thought it was broken and had been trying everything for almost 2 hours.

Based on the Owner's manual, these lights have nothing to do with the ethernet connection, although it is still likely an ASD-3N problem.

I was refering to LEDs on the ethernet connector on the Rear Panel



Here's a close up (+ my additional labels/arrows):



I don't see these LEDs described in the owner's manual, but they are common on RJ45/ethernet connectors.

Since I don't ever see these lighted (using an active CAT5 cable), I'm suspecting the dock has problems (most likely hardware).

Although not familiar with the dock, you're likely correct. GIve Denon a call to confirm.

While here is the latest update.. After messing with the receiver some more, I am able to get some sound but only Stereo. I cannot get DTS or any surround sound. Do you think I have a bad HDMI board. If yes, where can I find one cheap.. Please advise.

Are you able to get audio to all speakers using the "5CH Stereo" surround mode? Do the test tones work now to all speakers? Do non-HDMI sources provide sound to all speakers? If it is related to the HDMI board, that will likely be very difficult to obtain give the model is 5 years old and most parts likely discontinued. Although HDMI boards generally cost $200+ so you would likely be better served investing in a newer model rather than attempting repair.

Picked up a used 2808CI recently for a very generous price. Very pleased.

Previous owner dumped this cheep because the unit would go into PROTECT at the slightest bump. Just turning a knob would do it. When I got it home I opened it up to see what lurked within (always unplug your unit B4 U try this. )

Found a small white connector (#512) on the power supply that had squirted out of its socket. Gently reseated this plug, and unit was good as new. One thing I noticed is the interior is a mass of connectors and cables. This kind of construction I suspect will be vulnerable to jostling. The slightest intermittency will likely cause the electronics to go berserk.

Curious about my new funky remote, the touch panel seems to have no effect on my other Denon units. My DVD player ignores it. Any thoughts?

Have you tried entering all the Denon pre-set codes listed in the back of the Owner's manual and using the procedure on p. 51? If the purchase did not include the Owner's manual, you can download it from Denon's website ....

Thank you jdsmoothie, remote worked the DVD deck fine.

Like they say "as a last resort..."

Hey all - just ordered a used 2808 reciever - and I am very excited to take advantage of the TrueHD!

I was reading through the setup manual and I had a quick question.

I ordered a setup mic as well for this unit so I can do the auto speaker setup. (first - is this recommended?)

I was reading about the various playback modes - and liked what I saw about: PureDirect.

However, it says that all EQ functions are turned off during puredirect playback - will this affect the auto speaker setup in any way - or are they mutually exclusive?

If I am using this receiver to watch blu-ray movies with DTS, TrueHD, and DTS Master Audio - is there any benefit to using the Puredirect mode?

the whole point of "Pure Direct" is to avoid any processing. So, yes, using Pure Direct (or regular Direct mode) will bypass Audyssey.

For movies I would recommend NOT using Pure Direct and instead using the standard decoding mode so you can take advantage of the Audyssey MultEQ XT room calibration.

Pure Direct on these models is really intended for critical 2ch music listening where you want the most "untouched" signal possible, and is really only useful if you have really nice speakers and a room with great acoustics. Otherwise, the benefit of room EQ will outweigh the advantage of the "unprocessed" signal.

For multichannel audio (e.g. HD audio codecs) you just want the straight decoding of the signal, which is activated by using the "Standard" button.

What AVR model are you currently using as even older HDMI AVR models that cannot decode compressed HD audio can still play uncompressed HD audio when decoded by the Blu Ray player? Yes, you'll want to use the Audyssey Setup mic (DM-A405). PURE DIRECT is generally not recommended as it will disable Audyssey.

Right now I am using the AVR 2803 - which is optical not hdmi.

When I receive the used 2808 - I will want to set it up manually at first I guess (since I will have to wait for the audyssey mic to come in.

Is there a way to restore the unit to defaults in case there are changes in there from the old owner that I do not want?

PS - The unit did not come with a remote - but I will still have the remote from the 2803 - should this still work?

Microprocessor reset procedure is listed on pg 50 of the manual -- if you haven't yet, download it from Denon's website.

Manual Link: http://usa.denon.com/DocumentMaster/US/AVR-2808CI-OM-E_102.pdf

Here is a snap from the manual on the reset procedure:




The remote from the older unit should work fine with most basic functions like power on/off, volume, menu navigation, surround mode, and input switching. You might find that some inputs on the newer models are not accessible with the buttons on the old remote, and you also will not have a button to turn Audyssey EQ on/off... but that's not a big deal because once you turn it on (which you can do via the OSD menus), you won't need to turn it off

I might recommend investing $50 in a Harmony remote which will make your life easier overall
