I have had this tv for about a year and have just noticed my picture quality is not very good. I know over a year it has taken me this long, which is why I wonder if it is just recently. When I watch a basketball game for instance and the view is of half court with all ten players on the court I cannot make out the players. It is very blocky like the resolution is awful. I cannot get an anwer from panasonic and thought it was my direct tv signal but the tech came out and checked my signal and said it was not that. Is there a way to improve?
