Original query:

My 4311 has performed flawlessly for 4 years now...however, this evening, I stopped getting audio from all inputs (everything HDMI). Video still works fine. Did some google sleuthing and came up with various fixes. Of course, the first thing I tried was to make sure the inputs were assigned correctly and nobody accidentally hit a button they shouldn't have (happens with a 5 year old). Next I did a microprocessor reset...still nothing.

What really concerns me now is that even the test tones aren't making it to the speakers. I believe this tells me that it isn't an input issue at all since the test tones are local to the machine. My last ditch effort was to try blowing in the headphone jack..supposedly dust buildup over time has been known to trick the AVR into thinking headphones are plugged in...still nothing.

Am I missing anything or is my 4311 shaking its death rattle?

=================================================

Follow-up

Digging into it further, it seems like the receiver is not recognizing that I have speakers hooked up at all. I even tried just plugging in headphones to see if I could get sound and nothing. I used Pandora internally from the receiver through headphones and heard nothing.

I'm stumped.

Does the Tuner work? Try doing a soft reset by unplugging the power cord for 10 minutes. If still no joy, try doing about 4-5 microprocessor resets in a row as doing a few more has been known to resolve issues a single reset did not resolve.

Thx for response, jd. I unplugged the power overnight and restored this morning; no change in status. I did at least 4 resets during the course of last evening, but not consecutively...so I will try that.

Another oddity: I cannot access the tuner. I'm hitting the button on the remote and it is not switching inputs. When using the manual input selector on the unit, it is not an option.

The left hand side of the 4311 display screen only shows "Dig" and nothing else. It used to display a number of speakers over there. I cannot recall if this is the "signal" side or my speakers. I also plugged in the Audyssey setup mic and cannot navigate anywhere on the main screen. "Auto Start" is highlighted by default and I cannot select it via the remote or the unit controls. Nor can I move up to "Amp Assign" or anything like that.

This all happened in the course of a few hours while the unit was on. I had left apple radio playing while I was out of the house for a couple hours. Came back to no sound.

Is it possible there was a power surge as this could have caused the current issue? Does sound like it's down for the count though.
