Hi @eton..!!

Yes, you can turn off subtitles on your LG TV without the remote by using the physical buttons on the TV or the LG ThinQ app on your smartphone.

1. Using Physical Buttons on the TV:

• Locate the Power Button: This button is usually found under the LG logo at the bottom of your TV. 
• Navigate the Menu: Use the volume and channel buttons to navigate the on-screen menu. Look for the settings menu, where you can find subtitle options. 
• Turn Off Subtitles: Once in the settings menu, locate the subtitle option and turn it off.

2. Using the LG ThinQ App:

• Launch the LG ThinQ app on your Android or iPhone. 
• Connect to Your TV: Open the app and connect it to your LG TV by following the on-screen instructions. 
• Control the TV: Use the app as a remote to navigate to Settings > Accessibility > Subtitles and turn them off.

These methods should help you turn off the subtitles without using the remote. 

Hope this was of help to you. Revert back for any further help.
