Last night notice the HD channel I was watching started to distort like it wasn't getting a good signal. I get my HD off antena. So went to all the other HD channels I have to see if antena was bad. But all the other HD channels all I got was black screen and sound and that was it. I turn it to the annalog channel no probem picture. So I went to master bedroom and turned on Panny plasma and all HD channels worked in there. So is it possible that I lost my HD tuner in my tv.
