Sony will provide software updates from time to time in order to enhance functionality and provide users with the latest TV experience. The easiest way to receive software updates is via an internet connection to the TV.
If you want to check if your software is up-to-date, select [System update] from [Settings] — [Device Preferences] — [About].
Updating software via USB storage device
If you do not have a network connection, you can also update the software by using a USB storage device. Use your computer to download the latest software from the Sony support website onto a USB storage device. Insert the USB storage device to a USB port on the TV and the software update will start automatically.
If you will update the TV software by using a USB storage device, you should read the cautions for update by USB storage device on the website.
