Samsung LCD 42 inch (LE40c650l1K) I came home from work the other night & switched it on & the screen was distorted & split into horizontal lines & squares & there was a pixelated trail behind moving images. I've had a very similar experience when the graphics card went on an Apple Mac (new logic board = emotional) After a couple of minutes the picture returned to normal. This happened about 4 or 5 times, so I'm assuming it's a bad contact perhaps on the screen. So I gave the screen a squeeze around the sides & the issue hasnt returned over the last couple of days. I'm concerned of course it will return & by not dealing with could worse the problem further down the line. I've tried googling this issue but am not sure of the correct terminology. I've attached a photo below, & the aerial was unplugged at the time hence no picture at all in the photo - but it shows the squares. http://img98.imageshack.us/img98/363/screenne.jpg Any advice would be welcome. Cheers.
