I purchased this TV about a month ago. All was fine in fact great but then I noticed vertical lines (more like bars about 2 inches wide) predominately on the left hand side of the screen. I first noticed it watching a football game whilst the cameras were panning and thought it might be a processing issue. On further exploration I now see it whenever there is a single light colour across the screen. It is there on the ambient screen options too. Does anyone know if this is a settings matter or is it a fault with the TV?
