My PANASONIC VIERA TX-55CX400B is not showing the full screen on the tv show. It seems to be cutting some parts out. Before when I put my tv on auto it will cover the entire screen but now it has 2 black bars on the sides. Even when the TV was without the black bars it still seemed to look like it was cutting some parts out. Any help with this? Also if you can't help how can I remove the black bars on auto mode and put it atleast back to how it was before. Additionally I did some searching and it said I need to enable "full" mode and put it on "size 2" however I cannot find any option to find out how to enable/disable full and put on size 2. -Thank you in advance.
