In response to your query about the (HDMI Audio Unavailable)
I went thru the same thing and actually had Comcast send the strongest signal which took 30 minutes and still no sound! I haven't called back because I used the the normal Audio cables and ran them out of the receiver and directly to my Bose system so, no worries! I am going to research this further and will post my final results. I also ran my components as well so my family can watch the monitor with the elephant ear sound. 
p.s. With the component hook up you can only get the Audio when in component mode, not HDMI!

My 5060 had no TV signals to worry aout for the first 6 weeks either. It's connected to my receiver (Denon 2807) by HDMI. Until last week, the only signal it got was from my DVD player (Denon 1920, HDMI to receiver for movies). No problems with black bars on the sides, just on the top and bottom. BTW, tried component but HDMI is much better for the DVD player and somewhat better for the sat box.

On the bright side, AVS has all the stuff we need assuming we have enough time to find it and read it.
