I just bought a new rx-v573.
I plugged in my sony blu ray player to the rx-v573 via an hdmi cable.
I then plugged my rx-v573 to my television (samsung hl56a650) via hdmi cables.
The back of the rx-v573 is connected to speakers in the wall via speaker wire.
Picture and sound are great, UNTIL I tried to change the sound of the receiver via the knob on the receiver or via the included remote--doing so results in the video playing turning to black, and the TV says hdmi1 720x480 60hz with a black screen. The audio is uninterrupted but the video (screen) goes black.
It looks like the black screen you get when you try to change tv inputs. The sound is not interrupted, its just the video that is interrupted which is super annoying as you can imagine.
Does anyone know what I have to do here, I have been searching for hours. My TV is a 1080p TV and the picture looks 1080p, I just dont know why the screen goes black and why it would say 720x480?
Any help would be great. I cant return the unit since i watied too long to open it (over one month, and i got from amazon.com)
