Welcome to our community.
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. If your TV is 42" or less, you can pursue service by carrying your TV in to your local Geek Squad. You can schedule an appointment by visiting We're Here to Help and selecting "Make a Reservation" under "Getting Help is Easy." If your TV is larger than 42" please call Geek Squad at 800-433-5778 to schedule a technician to visit your home.
I hope this helps. Thank you for writing to us.
