Hi there! Your TU7000 may need a firmware update, as a new firmware version was released in February 2021. Here is how to update your TV:
Using your TV's remote, navigate to Settings, and select Support. Select Software Update, and then select Update Now. New updates will be downloaded and installed on your TV. Updates usually take a few minutes; please do not turn off the TV until the update is complete. When the update is finished, the TV will restart automatically.
You may also want to enable automatic updates for future convenience.
Select Settings > Support > Software Update, then select Auto Update.
