I have a Panasonic TCP42-S1 hooked up to a Bell Expressvu HD box. Since we've hooked it up, it cuts off the image in both 4:3 and 16:9. The TV is set to full and when I contacted Panasonic, they told me that it was a problem with the satellite box. It looks as though the TV is zoomed in, but I can't find any settings for this. If you know how to fix this, please let me know. Thanks
