Facing TV Problems? Ask a TV Technician.
Hello, Please unplug your Cable Box and your TV both from power for 1 minute and then plug them back in and let me know if the issue is still there.
If so, then the issue is being caused within the cable box- since your DVD player is working fine. In that case I need the brand (Make) and model number off of the front of the Cable Box in order to assist further.
