I have a Sony Bravia KDL-40S4100 that has started having a vertical band of ghosting on the first (aprox 4 inches) on the left side of the screen. Still see the picture, but green seems to be the main color of ghosting. This all developed the same day that Directv added whole house DVR service. I don't know if the moving the TV caused the problem. Can anyone tell me if there is a circuit board or something that I can check to fix.
