What a rude comment. Postdog is absolutely right, CEEFAX and ORACLE died with analogue TV; he was trying to be helpful and asking you to clarify your post.
Have you tried the button on the top row of the remote that gives this
/ option. I think pressing the / icon moves the tv through 3 phases. Picture no text, picture and text, exit text.
Hmm. Different models have different remotes. Your remote may be this method.
While watching a program with subtitles/closed captions, press the CC/SUBTITLE button to turn the subtitles/closed captions on or off.
Using the Touchpad Remote Control, press the Control Bar (....), slide the touchpad to highlight the CC/SUBTITLE button, then press the touchpad to select.
