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.
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.
