I turned on my tv to discover that it has an all blue screen with a 1-2" key symbol in the bottom left hand side of the screen. The tv cannot be turned on or off manually only with the remote and no other buttons work except the power button on the remote. I don't believe that i ever set any parental controls as i have no children. I unplugged it for 24 hrs and turned it back on to receive the same problem. Not sure where to go from there i read that sometimes you need to take the cover off and remove the internal battery is that wise?
The Tv's Child Lock has been activated...
Hold down the F button and press the MUTE button to unlock.
You can only remove the child lock using the remote.
