I have a Panasonic TC-P50S1 and a Panasonic DMP-BD60. The bluray player is in my media closet from the closet to where the tv is contractor ran rapid run hdmi cable. In the closet there is Rapid run hdmi active wall plate by the tv a passive wall plate. The directv hr21 works fine but even when I plug the Blu Ray player direct to the wall plate i get the u73 message. If I take the player to the tv and plug it in it works. Can the problem be the wall plate even if directv works well our can it be something else. Help Please
