Your tv is locked!
If you have a blank screen with a red key on the bottom left, simply press the (function or F) button and the mute button at the same time. This will unlock the screen and allow you to view the channel as desired. • If your TV asks for a 4-digit code or password please enter 3308 or 6688 to unlock the screen or reset any preset rating levels. • If you have a GT2011J or GT2011S Television, hold the (Display) button for 10 seconds, it will unlock the screen. If password or code is requested, try 3308 or 6688.

Black Screen with sound

make sure the TV time is correct. Reset the time. if that does not work, but the TV operates ok, it's in the circuit board, or could be a fuse problem.
