Hello. More and more people are using cable boxes or satellite tv set top boxes to receive their television programs. If you have cable box then you will more than likely have to turn it off and immediately press the menu button on it to dispay the hidden menu where closed captoning can be enabled.
After scrolling down and enabling it simply use the on/of button on the front to go back to your tv channels and you should have closed captionng.
Satellte remotes usally have colored buttons and the closed captioning is accessed by pressing either the yellow or green one.
Your specific cable or saellte tv company can give you detailed instructions on how to enable closed captioning.
If you are not using a cable or satllite tv receiver there should be a closed caption cc button on your tv remote or a menu option to enable closed captionng.
If the problem is that you don't have a remote try
