Sorry about that - I meant AVR. You would place it between your 591 receiver and TV display (the female HDMI connector side, toward the receiver). It would pass the audio and video HDMI information as is, and replace the power with its own wall-wort power. In replacing your TV and getting it to work, it might still be worth a try because some displays need to see power and others may not (not sure here). I have a Panny that must see HDMI power before it will enable, but there could be others that don't care. I would think the power might be suspect however, since your receiver works with everything else except the Directv receiver. When you have all your hair on the floor, it might be worth a try, and unfortunately, there's no other way to test for this problem. I found that it was the capacitive loading on my Directv receiver that caused its HDMI power to be unstable, hence one cable worked and another didn't. The same thing could be happening when your receiver is in the HDMI path.
Good luck. I lost my hair a long time ago.
