Question

Hello. Have a brand new LCD tv Phillips 47" 47PFL5422D/3747PFL5422D/37. Just tonight noticed a very thin greenish, bluish vertical line running thru the picture. It is about 13 inches from the left side of the screen. It appears in the TV mode where the cable is directly plugged into the tv. Also in the mode where the cable is routed through our VHS/DVD recorder. And also when playing a DVD. Any help is greatly appreciated.
