Hey guys I just purchased it and the picture is really nice. But I notice very light but enough to annoy the hell out of me Grey bars across the screen when the image is on a white background. Even in the ps3 menu when scrolling left and right to different applications I see them faintly in the background they are light vertical lines/bars of some sort. I bought the TV from Walmart on the 27th should I take it back? Or with LED it's inevitable?
