Lately I have noticed a rather strange problem with this set where the hue of the picture starts to flicker between what I have it set to normally to one that looks blueish green. After going back and forth, it eventually stays on the blueish green hued picture. It's almost as if I'm watching the TV with a pair of blueish green tinted sunglasses. Does anyone out there know what might be causing this? It happens on all my video inputs, so I doubt that my DVD player is the root of the problem.
