A demonstration of my TV that shows vertical ghosting lines.
TV is: Toshiba 40xv640u 40" TV 1080p & 120Hz capable.
Signal source: DSub 15 1024x768 at 60Hz.
Long description of problem:
When the TV is first turned on, there is no problem with the display. But, after using the TV for a little while, vertical ghost lines appear in areas which the display showed an image.
This is most pronounced when the colors are high contrast compared to the neighboring area. The lines do no appear when there is a new object there, but when the object is moved or disappears, the vertical ghost lines remain. The vertical ghost lines also appear when there is a strongly colored object (i.e. a red clock) around a black area.
Over a short period of time, red vertical lines would extend from the top & bottom of the screen towards the object, even though the area around the object is black. This phenomenon occurs even with the TV's builtin menu.
