I picked up the Sony STR-DH820 a few months ago and things were all good. I had my Samsung BD player setup using HDMI and had no issues. When I finally settled down and bought some new HDMI cables to hook up the X-Box and PS3 to the receiver, I have the problem that none of my inputs were giving any signal. My satellite is using component video input with HDMI out to the TV and that was working good, so I tested it's HDMI out and got nothing there as well. Each component HDMI output to the TV works, so it seems that my HDMI input bus (if that's what it's called... I'm new to this scene) has crapped itself. The HDMI out works fine as is evidenced by the satellite signal still working. Oddly, I didn't always get a blue screen with "No Signal" drifting across my TV when I was trying these out. I would sometimes get a black screen with a "Not Supported" message with a flicker of an image from the component being tested.
