I have a 32" Sanyo that has developed a darker spot on the right side of the screen maybe half the length of the screen. It can only bee seen on certain colors. White and black you can not see it. It looks like a shadow. It is away from the edge of the screen approx 2 inches toward the center. I have heard it could be a wiring problem with the HDMI or that it needs to have a black white sequence pattern ran on it for a day. Any help would be greatly appreciated!!!
