Hi @Sandra1 just for clarification do you mean close captions or subtitles? They are two different things but look similar. Subtitles are basic transcripts of the voice portions of the content; closed captions on the other hand contain the voice transcriptions as well, but also include notations for music and other background and secondary sounds, say "phone ringing," "birds chirping," etc.
The first thing to do would be to make sure you're using the correct setting for CC or subtitles as processed by the television. It could have been reset or turned off for some reason. The other thing I'd check is the version of CC, there are different types and you may need to choose the correct version for your television and even your country.
I'm assuming you're using the CCwGTV if so, I'd also go to your settings/system/ and on the right side of the screen choose "Accessibility" and make sure settings there are on and using the correct options. Be sure to look under "Captions" and make sure the appropriate toggles are set there. Keep in mind videos you cast, say from YouTube or other places, may need to be toggled on individually and aren't necessarily automatic. In those instances, you'll want to click the "cc" emblem at the bottom of the screen from the handheld device. Hope this helps.
