Last night I was watching satellite and after Sex And The City ended I turned down the volume to jump on the computer just to pass time for my next show to come on. When the show came on I turned up the volume like usual and NOTHING. There was no sound at all. What I noticed different was that the DIGITAL light was flashing repeatedly like it couldn't get a signal. The light will flash for 10 seconds and then remain lit, but with no sound. I checked the back of receiver and satellite and both connections were solid. I then switched to the CD source which uses a optical connection and still NO sound. I tried a DVD out, which was working just fine earlier that day and no sound. I then tried switching to the TUNER to see if there is something wrong with it being able to decode a Digital signal and the TUNER had no sound. So all of my digital and analog sources have no sound. I have my DENON acting as a preamp to a Parasound 1205, so to make sure nothing was wrong with the amp I did a Test Tone check. It worked, I am still getting power to the speakers but no sound using any devices. Is there something wrong with the DACS? Is there any other tests that I can do to narrow down the problem? The Denon is about 1.5 years old and was bought at an authorized dealer, but I hoping not to have it shipped out. Has anyone heard of this issues with a Denon?
