LCD Suddenly has strange line on screen

[Vegetarian]

Ive had a 32" AOC LCD TV for over a year and its been fantastic - images looks far better than some branded screens.

However, the last few days Ive noticed a funny horizontal line 1/3 the way accross the top middle of the screen. Its quite faint and only noticible on some shades - black and white I cant see anything. It looks more like a shaddow than faulty pixels. Any Ideas?

Any paricular window, taskbar or any general line of high contrast that sits at that point often?

general line... general PC and tv use you cant see it... but sometimes you can see it due to the shade thats shown on the screen at the time... normally if a film is shot in low light.
