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.
