In the past few days I have noticed a huge drop in my picture quality. Noenthing that was HD and looked it is looking like HD now. Picture is soft and mushy, even darker. There is none of the defininiton and sharpness of an HD signal. Looks like a modest SD digital signal acrross the board and not even very sharp for that. I have two sets, one fed by Comcast STB (SA 4250) and the other fed with cable card in set. Both show same effect. No connection changes, wiring changes etc. Anyone guess what may have happened? Comcast did add a bunch of HD channels back in June, but the PQ was fine before and after they did that....until this week.
