I just purchased a Panasonic plasma TC-P55GT50 and have it connected to a DirecTv Genie receiver.
I did not notice at first, but after getting used to the new gear, I find on the local ABC channel and on that channel only, I have a dead area on the picture. It extends about 1" from the right side about 6" up from the bottom. It is about 3/16" high. It is always there on this channel. It does not occur on any other signal or input. DVD is ok. Internet is ok. Only on the DirecTV channel for the local ABC.
Panasonic CSR says it can't be the TV since it only appears on one channel.
I switched out receiver boxes and I still have the same problem.
I have 2 other tvs in the house, one LED and one LCD. Neither have this problem.
What combination of the Panasonic Plasma and DirecTv could be causing this?
