One of my 722K's started outputting sound with crackling & popping. When this happens you also see a short thin horizontal line in the picture. Since this 722k is also connected via A/V cables to a DVD burner I switch to it and the problem was gone. So it was coming in over the HDMI output. I checked other HDMI inputs of the TV and no problem. I did a hard reset of the receiver and that fixed the problem! What I want to know is can anyone explain what causes this kind of problem with the HDMI output of the 722K. I'm just curious about it.
