How to turn off closed captioning and keep it OFF
What's your source for the video? For video from a set-top box (Blu-ray. cable box, etc), you have to disable captioning at the source. The TV's CC control only work for OTA and unscrambled cable channels when the incoming signal goes to the RF (coaxial) ANT/Cable input. If this is your source, press the Menu button. Use the left/right arrow buttons navigate to the Preferences menu. Open this sub-menu (down arrow) and highlight the Base CC mode. Use the left/right arrows to change the current mode to Off. Press Enter and then press Exit to save and exit the menu.
The set-top box may not have an option to control the closed captions from the remote but accessed through the On-Screen Menu. On some satellite receivers that provide a signal to a primary and secondary TV. to enable or disable the captions on the second TV at the primary TV's set top box. Then both TVs will show the captions. On my IPTV box, I need to use a password from the service provider to access the Settings menu. The control for the Closed Captions are in the Hardware > Audio Settings menu.
I hope this helps. Please add a comment with the specifics about your devices/source. I can try to find the directions for disabling the captions for your source.
