Why does my Panasonic HDTV have a black border around it?

Episode 999 (1:13:57)

Alex from Chicago, IL
Panasonic HDTV

Alex has a Panasonic ST60 and he really likes it. However, he's getting a black border around the screen whenever he tries watching anything. Leo says to look into settings to see what his aspect ratio is set to. If that's set properly, the screen should go all the way to the bezel. If it doesn't and he's verified that he's using the correct settings, then there's a repair issue. Contact Panasonic and have them fix it under warranty.
