Closed Captioning is displayed even though it is disabled in the TV menu.
If Closed Captioning is being displayed even though the CC option in the TV menu is set to Off , then it is being produced by another device, such as a cable or satellite set-top box. To remove the Closed Captioning from the TV screen, it must be disabled on the device that is decoding the Closed Captioned signal.
NOTE: Some set-top boxes may automatically display Closed Captioning on the TV screen when the set-top box sound is muted. If this is the case, turn off the Mute function of the set-top box.
