the model is TH-42PX50U and when I put on the HD channels there are four rows of 1 inch boxes, 16 boxes per row, that appear on the screen. the are a white discoloration that makes it annoying to watch. when I watch teh normal channels or on demand there is a lot of light blue lightning type static across the scfeen that also make it hard to watch.

Is this normal for a two year old Panasonic Plasma?
