Hi everybody, I just bought a Panasonic TX21AP1 21-inch Quintrix TV which is great, except that the picture doesn't fill the screen. There's a black stripe both above and below the picture, each stripe being about 1 inch deep. The adjustable aspect ratio is set to the standard 4:3, so I'd expect the picture to completely fill the screen, but it doesn't at all. I have an old TX25A2 which is fine by comparison. Does this sound like there might be a problem with the TV? Thanks for any thoughts.
