HELP PLEASE!!! About three weeks ago I noticed a dark line on the right edge of my screen. Over the past three weeks the line has slowly moved about 1 foot to the left. everything to the left of the line is normal. everything to the right of the line is darker and the color is not the same, but there is still a picture. A second line has now started and is about 3 inches to the left of the edge of the screen (and also slowly moving towards the center). Same problem with the second line being lighter on the left (same brightness as right side of first line) and darker on the right. I've attached a small photo to show what I'm talking about. Any ideas????
