I just got this TV last week and am already experiencing problems. On the right side of the screen, in particular the bottom-right corner, the picture is dark and there is noticable color bleeding. Also this part of the image is not as sharp as the rest of image. Is there any way to get rid of this manually? If not, should I: a.) Contact Samsung or b.)take it back to the store for a replacement. Any info would be greatly appreciated.
