Denon AVR990 HD Radio Doesnt work, skips.

3/2010 Denon AVR-990 - Called Denon to complain that after every 10-45 minutes the radio gets stuck and won't play. Have to manually turn receiver off and back on to play the radio every 10 minutes or so. Was told Denon is aware of the issue and reviewing and testing. They have been aware of the issue for months(~8/09). No consideration was offered like we will be glad to inform of the fix, nothing. We also purchased Denon's expensive blu-ray to go with it and I hate that I am unable to listen to the radio without knowing if I ever will be able to have radio for the next 10 years until I upgrade my home theater again...SUCKS!

I swapped out my Panasonic receiver for this receiver, and it does make my music sound better. It seems the clarity I hear from my CD's is a result of this company focuses on receivers. As a oppose to companies like Panasonic or Sony who make an array of electronics and have to keep track of many product quality issues. Denon focuses on a few products and do them all well. I purchased this receiver as a refurbished and paid sixty percent of retail. When I got it home, I had a problem with the Cable/Satellite HDMI port, not picture, no sound, nothing. Called customer support, updated the firmware and software, still the same problem persists. I finally, figured out what the problem was. The problem was, I was not pushing the HDMI cable far enough into the port. I suspect that was the issue that labeled this receiver; refurbished. That was the only issue I have had with the receiver with sixty percent off, what a value.

I bought this model because I wanted the Spotify feature and it had a secondary zone. This thing has been having Thermal errors since the beginning. I applied the updates and it still didn't fix the issue. The reciever is out in the open and does not have any airflow restriction issues. There are no other components on it. I have checked and rechecked the connections to the unit to enure there are no loose wires or connections. When I google Onkyo "Thermal Error" the only model that shows up is this one.

Stay AWAY from this model. I should have bought a Denon

I was happy with it until a firmware update made it unusable (no networking, internet nor sound).
Onkyo fixed this, for free, and when it was reinstalled it popped and smoked.
The wife asked if it was the 70's again.

Video works, but no sound is converted whatsoever. I have AUX, HDMI, Optical and coax all plugged in and no sound.

Not the most impressed with the Denon X2200W. There seems to be a lot of people facing the same issue with sounds dropping when connecting to an HDMI TV box: The sound goes off after I switch TV channel which basically make it impossible to watch HDMI TV properly. Denon support services are clueless and useless despite the issue being reported all over web forums. The shop swapped my receiver for a new one but nothing has changed.
The airplay works fine with my iphone but doesn't connect properly to my Mac Itunes. I constantly have to disconnect itunes from the Denon to reconnect in order to get the connection back.
Except those very annoying defects, the receiver sounds good enough but considering the competition of other receivers on the market which might be more reliable, I feel there could be some better choice than this Denon.

I have this player and the picture quality is good over the HDMI cable.  However my receiver does not have HDMI input so I use the digital coax connection from the dvd player to the receiver for the audio.  Unfortunatley there is a terrible delay between the picture and sound so I thought I would try the AV SYNC feature I was told this player has.  However it doesn't work at all for the digital dolby/DTS outputs but only works in PCM mode which is basically useless.  They should make that fact more clear in their spec lists.

i can get it to scan channels but when i try to play one it tells me there is no signal and i have the antenna (it required, even tho i didn't need an additional attenna) hooked up correctly. it's very frustrating and i haven't even been able to use it yet

When I first hooked this up to my surround sound receiver seemed to work great, but then I would either loose sound or get a green screen after switching inputs. This happened to me when I had game systems hooked up as well as my Blue Ray player and Roku. Tried working with technical support, but they couldn't help me resolve this. Eventually just had to give up.

Update - tech support got back with me and sent me a new unit. It is working much better now!

Item worked for about 3 hours then no sound would come from any channel/input combination.

D to A converter doesnt work.  Since my tv connects to my dvr which drives audio the only way I can use this is to plug into the dvr out jack which cuts off the speaker audio.  So I can only use it if I do away with my dvr which I don't want to do or use it to cut off sound.  No way to use it while others listen to the speakers.  Sending it back.

Update: I tried the optical cable from my Bose unit, and it started working.  No surprise, the one that came with it is really cheezy.  So Ill hang on to it for a whike, see if it keeps working.  I got a replacement at the local Chicken Shack for $20.

A comment about the seller: They never offerred to replace anything, only said I could ship it back at my cost and theyd email me when they received it with a "timeframe" for my refund.  Not real good service.

For the first two weeks I thought the Denon AVR3312ci was a great upgrade from my 3 year old Marantz SR7002. Sound quality was very good and the extra power was impressive. The speaker setup (Mythos One mains, Mythos Eight center, Supercube II sub, Mythos Four surrounds, and Mythos Six rears) went well but the manual is very confusing when it comes to manually selecting different sound schemes (e.g. Dolby TrueHD, DTS-HD(tm) Master Audio, Dolby Digital Plus, DTS-HD(tm) High Resolution Audio,etc.) Whoever designed the remote needs a remedial class in basic principals of "user friendly" design.

Two days ago I connected the AVR3312ci to a Linksys bridge to enable connection to my home wireless network. That process went very well. Yesterday the receiver started a 40 minute firmware update which, at first, seemed to go well. Video quality immediately after the firmware update was noticeably impaired. Within hours after that the output for both sound and video went completely out. A quick chat with Denon C/S this morning told me the receiver needed repair. Since I live 3 hours from the nearest Denon repair center, it was shipped today to a supercenter repair facility at a cost of $24.

Not sure how many others are having problems with their new $1099 receiver/paperweights but I must say I am really disappointed. It took two hours to pull out the AVR3312ci, put back in the Marantz SR7002 into my HT setup, pack up the AVR-3312ci and get it to FedEx for shipment. I'll update this review as I get more info on what the repair center finds. Right now I can only give it two stars. I can only hope it comes back from repair and works without additional problems!

UPDATE: The Service Center in So Cal did return the "repaired" receiver within 10 days. They did a firmware update checked the output and that was it. After two weeks the same problems returned. Sound would randomly drop out and HD picture quality went horrible after 10-30 minutes of watching when the receiver had warmed up - lots of high contrast ghosts/artifacts that could not be fixed with contrast or any other picture adjustments. Tried turning off HDMI Control function on both TV and receiver per Denon Support to no avail. Additional problems with function of specific remote buttons. If I plug the HDMI directly from the Cable Box or the BluRay player into the TV there are no picture or sound quality problems so I know the problem is within the receiver.

The receiver is back on it's way to Denon's So Cal Service Supercenter (I'm out another $25 in shipping) with a case opened at Denon USA on the problems I'm having. At this point I would say avoid any new Denon receiver. The quality of the product and the quality of support from Denon USA just isn't there.....

SECOND UPDATE: At the repair center for the second time the remote was repaired/replaced, the internal HDMI video board was replaced and the firmware was updated yet again. Returned within 2 weeks from my shipping date. Now, four months later, I can report that the unit has been working just fine. I've very satisfied with the current video and sound quality. But what a hassle to go through to get a new unit to work properly! Starting in December I've been getting another message from the receiver to do a firmware update but frankly I'm now too scared to do it!

LONG TERM UPDATE: Since the HDMI video board and remote control were was replaced I have not had any other issues. Getting great sound and am satisfied with my purchase. I have even successfully completed two firmware updates over the past year. IF YOU DO A FIRMWARE UPDATE YOU MUST USE A HARDWIRED ETHERNET CONNECTION TO THE INTERNET! DO NOT TRY TO USE A WIRELESS BRIDGE OR OTHER WIRELESS TECHNOLOGY TO DO A FIRMWARE UPDATE!!!

Bass output died about 4 years after purchase.  Tried everything I could find online to fix it...  but nada.

For something that cost almost $800, I am extremely disappointed.  I am in the market for a new AVR and reading other reviews ... wow... Denon, what the hell happened?  Baring any magical Denon fairy dust fixing my receiver, I'm ditching them for good.  Denon will be an avoided brand name for me for ... well ... ever.

Like the previous reviewer, had a similar issue with the hdmi switching, called onkyo, they said never heard of it before and suggested to get it serviced or return it.  we will see if the new one works.  the product might just need better packaging, protection for the HDMI board or need to ship the receiver separately from the speakers.

In general the Denon receivers are a great buy for price/support/features. Recently I bricked 2 e400's by simply doing a firmware upgrade. I performed the firmware upgrade for 2 reasons. First the internal Pandora software constantly paused and queued. Secondly I was advised by Denon support that the upgrade would resolve the issue. I have installed many of these receivers without issue. So I am not sure if these 2 receivers had an issue and I am just extremely unlucky or if Denon has an software issue. All other devices on the network workiwithout any issues. I tried 2 different routers from different manufacturers. I returned the Denons and got a Yamaha. The Yamaha connected and played internet radio without issue. UPDATE: I had the Denon connected to a switch, and the switch to the router. I found if I connected thw Denon directly to the router that it connected without issue. Which still leads me to wonder if this is a Denon network component issue or other.

I received the Denon AVR from Amazon at a great price, but it was not all it was advertised to be.  Supposed to be HDMI in and out but when I read the instructions the fine print said the receiver only transfers the video portion of the HDMI and I would have to use a separate digital cable from each component to the AVR.  Thats old technology!  Do not buy this item.  Go for one that is HDMI compatible.

Playback skips sometimes, it cuts in and out as you are trying to listen to the unit, it's
frustrating to say the least.
