I have defended my NAD on this board a lot and had no problem with it until this last week. I went to play a DVD the other day and had a white noise hum. I thought that it was the dreaded sound issue everyone on this board has discussed. As I went through all my various connections and the like, I noticed that the right channel on the receiver wasn't working from any of the digital inputs. When I use the analog inputs, it is fine. Any thoughts on what this might be other than a blown DAC? I currently using the analog outs on my SACD/DVD player, and frankly thought that the DVD players DAC always sounded better than the NADs, but now I have to be able to watch my HDTV with 5.1, and I don't have that now... Time to get it serviced, but I cannot stand it taking 2-3 weeks...

Sounds like a hardware fault. But may be worth doing a system reset if you haven't already done so.

".... the magic sequence is to press both the "video" and "tone defeat" buttons simultaneously for 5 seconds. When you let go of them, you'll see "AH RESET DONE". Then turn the system off with the main switch in back, leave it off for a minute or two, then turn it back on. ....."
