Problem with LCD Screen

Need a little help with a recent screen problem with my Samsung UE46ES7000, I have searched the web but can't seem to find a similar problem to mine.

I recently moved house and in transporting the TV I think it might of got bumped around the screen area, and when I turned the TV on it started flickering, then settled down and then a black blurred bar appeared across the screen (see Picture).

What I have found is when I turn the TV on, the picture is fine and then after 10minutes or so the bar appears again.

I have been pointed in the direction of the T-con but just wanted to throw it out their to see if anyone might of experienced the same kind of problem?
