I did a search but I cant seem to find someone who can fix this. I have black pillars on the left and right sometimes during a show for SD channels. It is kinda annoying I just got this HD setup today. The receiver is the HR22 and I have a Sony 55EX500 Tv. I can only fix the problem by changing my tv format from full to wide zoom. But when I change channel I have to change it back to full sometimes because the screen will fit it. Kinda annoying to do.
