I purchased a 2808CI new back in 2007 for quite a pretty penny. It's been working fine and I've been running movies, music and cable through it since then with very few issues. On Friday, I turned everything off as usual and left for the weekend. Come home Sunday night, and no audio.

Worse, I can't get audio from any source. In fact, I can't even get audio from the Test menu when it's supposed to test the volume levels of each speaker in my 7.1 setup. And no, I don't even get audio from the power sub. I have tried to reset the microprocessor, but it had no impact, nor did leaving the 2808 unplugged for 15 minutes.
Question 1: Any other ideas before I resort to calling service?
Question 2: If, as I suspect, the unit is now garbage, what would you do? Buy another 2808 or similar unit, or upgrade to some of the newer receivers? I'd rather keep the cost of this unscheduled replacement down to under $1,000 if at all possible, but at that price point would there be any significant upgrades if going to new equipment? FYI, I'm running a 7.1 system with one HDMI input (cable box) and one composite video and optical audio input (my XBMC). Output is to Pioneer Elite plasma TV and Definitive speakers. I don't anticipate needing multiple zones, so all of those features are useless to me, and I can't imagine ever needing more than 4 HDMI inputs. 3D television is not important to me either.
Thanks in advance for any recommendations!
