Facing TV Problems? Ask a TV Technician.
Please check that IF you're using a cable box- and IF you're using red,blue,green,red and white RCA cables that these cables are connected securely at both the TV and the Cable Box itself. The most common cause of this is a pulled red RCA cable on either the TV or the cable box side. If you do not find a loose cable then SWITCH the red and green (closest to each other) around on BOTH ends and let me know what happens with the screen and we can proceed.
