Anyone know why on dark scenes I might be seeing line roll, it is not completely horizontal it is more like a 20 degree angle, from left to right. Where there is no signal to the TV the line roll is very pronounced but only appears on very Dark scenes when I am playing a DVD. The DVD is hooked up via component (r, g, b) to the TV. I dont have cable or satalite so DVD is really the only signal I have. The cable I am using to connect the DVD is quality and I have swapped it out so I am guessing it is not the connection.
