Welcome to our community.
If you haven't already done so, try power-cycling your TV by turning it off and unplugging it for several minutes. This should serve to reset the TV hardware. You may also wish to reset the TV from the Settings menu. Please note: this will likely clear all custom settings, so be sure to make note of them (if any) before proceeding. You can find instructions to reset in the TV User Guide.
If the problem persists, your TV will likely need repairs. You can pursue service by carrying your TV in to your local Geek Squad. Please schedule a reservation by visiting We're Here to Help and selecting "Make a Reservation" under "Getting Help is Easy."
I hope this helps. Thank you for writing to us.
