Before I call for repair service (have no service contract), I would appreciate any ideas about what I might be looking at here. I have a Best Buy Insignia 30" Flat screen HD TV (1080i - 16.9 aspect), which I purchased 18 mths. ago. Suddenly, when set to display in 16.9 aspect, the picture is too big for the screen. No matter what format I engage, the picture is distorted in some way. Any setting, including Normal, other than 4:3 will send the image past the screen. On 4:30, I get a smaller image, which is warped horizontally, i.e., if I pull up a menu, the right and left sides of the box it appears in, will be curved inward. Likewise. when something is being broadcast that should appear straight, i.e., boards on a fence, they are warped. When I adjust the horizontal/vertical from the tv menu, it moves th image left, right, etc., but does nothing for the warping. Any ideas? Thanks, Yucca
