my 4 month old 55lm4600 JUST showed a green vertical bar of pixels from top to bottom of the display (if you actually look REALLY close it's an every other display of green and red but the green seems to show up the most) and to make it worse there's a horizontal line of blackish/blue pixels going from left to right all the way across the screen. my screen is fried I'm guessing??? I bought it at costco 4 months ago and now I'm 1 month out of the return date so I'm out there. I guess I have to call LG and get it replaced.
