All I know is that it has been reported to work with some issues where once did not.

Unhappy

Hello,

I have Denon AVR2312 CI since last 1 year. I am experiencing problems when i am in middle of the movie. The sound drops off. However this problem is resolved for short time when i plug out hdmi cable from hdmi out of AVR and plug it back in, but the problem again starts and i hear click sound before the sound goes off. I shall be grateful if anybody could help me here and suggest what the problem is. Also i would like to add here that sound completely goes off from center channel speaker and i can only hear faint sound of movie from left and right speakers.

Thanks
Gurpreet Singh

Same thing happens on my 2312ci along with a few other members here. I don't know if anyone has gotten it fixed from Denon.

I'm one of those who are experiencing the problem. It happened almost every day until I reset microprocessor. Now it happens Intermittently, like once every a few days. I thought it would be hardware related but it interesting that resetting tamed it down. Not completed fixed though. I'll try to reset it a few more times when I get a chance. It might fix the problem permanently if I'm lucky. I'm reluctant to take it to service center as it's hard to duplicate the problem. I have some warranty period left so I'll see how it goes for now.


By the way, do you have any overheat problem. I'm using a fan as Denon suggested but I don't really think I should. I have 5" clearance above. I never had to use a fan with several other brand receivers.

Never had my receiver overheat but it did get hot. Now I use a 80mm fan blowing across the top.

With open access to the front and back, 5" clearance above the unit should be more than sufficient without having to use a fan.

Ideally, you want the fan "exhausting" the air away from the unit, otherwise the fan can be blowing dust into it.

I tried resetting microprocessor, checked/reconnected all the cables. No luck. It works with no problem even for a few days. But sometimes it happens one or twice a day. When it loses channels, they usually come back within 10 minutes. I don’t need to do anything. All the channels just come back with the same click sound. Front panel still shows all channels when it loses the channels.

Question is, is it worth bringing it to service center? It’s still within warranty period. But it happens very randomly and short period of time. They might not find anything. I’m very reluctant to bring it to service center after I experienced overheat problem last year (see below)




Any advice would be appreciated.
My 3312ci has the EXACT issue.

Interesting.


I am loath to bring it to my nearest Denon repair center. It is a 2+ hour drive away. One way. Then, once I bring it there, I've got to replicate an intermittent problem. I foresee a lot of shoulder shrugging. Meanwhile, I get a lot of relay cutouts and sound dropouts.


The speakers are the same ones I used prior to purchasing the Denon 3312ci, when I had my Sony DTR ES 3 (I may have mangled the nomenclature) running. The Sony ran for about 10 years ( Bought it new the year it was released) without any issues whatsoever. I "upgraded" to the Denon due to HDMI input/output, not due to any shortcoming in the Sony.


Could the speakers have an intermittent internal fault causing the relays to cutout to protect from a short? Maybe. The speakers have just sat there; they don't get moved.


At this point, I am glad I've got a 3 year warranty on the 3312ci. I am not glad I have an issue.


I've done the soft reset countless times. I've done a hard reset about a dozen times. (The firmware was updated in May, the day after the latest release.)


I am frustrated, knowing that intermittent problems require tech support to focus on the unit until the fault recurs, and that type of time is simply not available. Unless Denon acknowledges that this issue is known and they have a repair, then I do not think I will get any kind of resolution.


Whereas I've been very happy with the 3312ci, that is tempered by the experience that the unit is unreliable. I never know if I'll have all the speakers working, or not.


My last effort with this amp will be to remove the banana plugs from my speaker wires and use the screw-down connectors.


It is disappointing that Denon has not produced a unit to last as long as the Sony it replaced.

Last year I put 2 140mm fans on top front of my 3312 blowing up. They have molex plugs so you can plug them in backwards to get 5v instead of 12v. They don't need to run at full speed. You can't hear them even when you are close.
Temps dropped from over 110F to the low 90s. Measured using an infrared thermometer on the top center near the front. Which is the hottest part.
They will be on my Denon x4100 when ever that is released.

All mfr's are going to have a small % of defective units. If this were a widespread issue, there would be a lot more complaints ... which there are not. You could call the repair facility you would use and ask if they can get a refurbished unit to replace the existing unit.

jdsmoothie,


Thanks. Your work here, as well as batpig's, was one of the reasons I bought the 3312CI.


My intermittent failure is frustrating. I'm sure that not all Denon 3312's have the problem that mine has. I have no idea what % does have the same problem. However, another poster, just upstream, does have the same problem. I really don't care what % Denon has: to me, it is a 100% rate of failure. In comparison, I NEVER had to reset my Sony, let alone have any failures, intermittent or otherwise.


I talked to a Denon repair rep. To say I was underwhelmed would be an optimistic spin on my conversation. I was told to retry the steps I'd already taken and then to take it into a repair center. In my dream world, Denon would have issued an RMA authorization (I have the original box; I registered it online) and allowed shipment to them. In a really good dream world, they would have shipped a new unit back after receiving mine. I understand that a refurbished 3312 would be the best I could hope for. However, I'd PREFER if I got a refurbished unit that it would have a NEW warranty with a 3 year clock starting when I received it. My unit started failing several months ago; a little over a year after I bought it.


The Denon rep did not volunteer if he'd ever heard of a similar failure. Frankly, I've read better advice from you and batpig.


I'll call the independent Denon affiliated repair center 2 1/2 hours away and find out what they think. I'm pretty sure it'll be, "Bring it in and we'll see if we can replicate the issue." That will leave me without an AVR for an undetermined period of time. I would expect it to be 3 to 6 weeks. That is poor.


I like it when it works.
I don't like Denon customer service. (Polite, but certainly not doing what is in my best interest.)
I don't like Denon repair service.
I don't like Denon "refurbished with warranty running out" as their replacement program.


Maybe I'm too pessimistic. I'd LOVE to find out I have a bad speaker. (How would I test, if it's intermittent, and happens at various volume levels?) Maybe Denon will step up and offer a replacement a day after I get it to the repair center. Shrug. After talking to their rep, I don't hold out hope for that.


Thanks for all your help.


Ken

There's no reason for a mfr to provide a brand new warranty on a refurbished unit, rather if one is issued, you would have whatever warranty period still remains from the original purchase. You may be better served shipping it to the factory repair center (PanurgyOEM) as not only are average turn around times quicker (1-2 weeks), but they would be better capable of resolving the issue. Prior to shipping, however, I would confirm that if Panurgy is not able to replicate the issue, that you would like a working refurbished unit in its place.
