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

On newer Sony TVs you press the CC button to cycle through the available settings for Closed Captions (CC): On, Off, and On when
Muting.

However, it looks like your factory remote control lacks a CC button and your TV menu appears to have a simple Off/On option for what Sony calls Caption Vision. If that is the case then you would need to manually turn on Caption Vision when you mute the television. That hardly seems like the solution you're after.

If you had an aftermarket remote control that could record macros you might be able to program it so that when you press the mute button the TV would mute and also turn on Closed Captioning. This would require the proper remote control and some expertise.

You must have its original remote control to close the closed caption.

Hi,
The Subtitle option is available only with the connected devices like DVD Player, Blu-ray Disc Player etc. The option avaialble in the TV is known as Closed Caption. The Closed caption option can be turned off by selecting the options below:
Press Menu button on the TV Remote. Select, Setup settings. Then select Caption Vision option to OFF. This option is for turning off the Closed Caption option in the TV to OFF. For disabling the Subtitle option in the connected devices like DVD Player and Blu-ray Disc Player, press the SUBTITLE button on the supplied Remote continuously to select OFF.
In few of the TV broadcasting channels the Subtitles cannot be turned OFF as this is being broadcasted with the channels.
Good Luck! KenSolutions

CC in the TV will only work while watching the TV's antenna or cable inputs; not the video inputs.

Try a master reset on the TV. With the TV powered on, hold down the"UP" button on the remote control.. Then, while holding down the up button, press the power button on the TV (not the one on the remote). Please let me know if this works and be sure to rate the solution. Thanks!

Do you use a Home Theater receiver along with your televison?  Are other components, such as a DVD player, VCR, Blu-ray player, etc. connected?
If so, it's possible that the Mute function on your remote is muting the sound from your receiver, and not the TV itself.
If that's the case, you'll need to look at the details of the "default" buttons for your activities, and see whether the Mute function is associated with your TV or your receiver.  If it's set for the receiver, you need to change it to be associated with the TV.
