Welcome to our community, SNB.
If you haven't already done so, try power-cycling the TV by turning it off and unplugging it for several minutes. This should serve to reset the TV hardware.
If the problem persists, your TV will likely need repairs. You can schedule an appointment for a technician to visit your home by calling Geek Squad at 800-433-5778.
I hope this helps. Thank you for writing to us.
