Welcome to our community.
With apologies, as your TV has not responded after power-cycling (turning it off and unplugging it), it will likely need repairs.
Please call Geek Squad at 800-433-5778 to schedule a technician to visit your home. Please remember: as this TV is outside the term of the factory warranty, repairs would be at your expense.
I regret I do not have better news for you, but I hope this helps. Thank you for writing to us.
