Greetings friends & thanks in advance to anyone willing to take the time to consider my post.
My Denon AVR 4311ci will not send a signal to my subs . . . I called a local A/V serivce center & though he didn't inspect my AVR, he did respond with "well, if you're getting no signal thru to your subs, then it's likely an issue w/ the motherboard" & he further stated that "if this were the case then it'd likely be more expensive to repair -vs- purchasing a new AVR" . . . did I already say: Grrrrrr!!! (((Side Note: I ran Audyssey (several times) & it would never recognize my subs; I was able to skip the subs set-up during the audyssey process . .. but sad to say, 'no subs for me!' . . .))))
Anyway, so here are my questions:
1) Does this sound right? This Denon was my first purchase of a receiver of this price range; but I find it so hard to believe that the repair cost could be over the $1,600 that I originally paid.
2) I purchased this in 2012; so, it's been about 5 years & kaputt . . . it doesn't seem like I should be having this sort of issue after only 5 years.
Well, I guess that's about it for now . . .
Again, thanks
Have you tested the sub? If not connect a CD player or any other known good source to the sub input and see if you get sound out of the sub.
If the sub works then the problem is the receiver.
If it is the receiver go to your manual and do one hard reset back to factory default settings and reset up your receiver. If that does not work then yes, the receiver does need replacement or repair.
Unfortunately five to seven years is often the life of receivers.
Now the tech may be right or wrong. It could be that the output socket for the sub has come off the board, especially if a heavy cable has been hanging from it. Sometimes if you are skillful you can repair this type of problem.
Any other type of problem is likely to require a new board. These days boards are just about impossible to service because of robot mounted surface components.
The next issue is that these days the manufacturers do not release service manuals and or circuits to anyone who is not a company certified repair center. Without that finding the problem is impossible.
The next issue is that finding the part even for the repair center may not be possible.
Finding spare parts is a problem across the industry right now. Denon/Marantz have sold their parts business to Encompass, who seem not the stock parts. Why I don't know.
Anyhow I would contact Denon for their nearest certified repair center and contact them.
The tech is right in one way, the cost of repair may well exceed the cost of the depreciated value of a five year old receiver. If not exceeding it, will be close.
Finally, if you do have to replace this receiver, do not get another receiver. These days receivers have too much crammed into one box, especially processing and power amps.
I personally have never liked the idea of receivers and don't use them and won't.
I strongly recommend a pre/pro and external amps. Reliability is likely to be much better that route. I note pre/pros on the second hand market hold their value much better then receivers. Overtime if you go that route you will be money ahead.
I note the my 10 year old pre/pro is fetching 2/3 of its original price on eBay at the moment.
