What causes these? The display/tv looks great with bright, vibrant colors but when you get to medium shades of colors and greys, there's a bunch of vertical "shadows" in different areas of the screen. If this the light diffuser/spreader/whatever not laying completely flat against the panel? Slight wrinkles/lifting off of the panel? Picked up a 40" television cheap because of this "problem" and just curious if there's an easy diy fix or will dust in the environment end up making the image worse with specks?

Again though, it has even lighting with a white/red/blue/green 255 hue. Eyes playing with the mind I believe
