Getting updates on a non-connected TV
If your TV is not connected to the Internet, you can still get system updates by using a USB flash drive and a computer with an
Internet connection.
To get a system update, navigate to Settings > System > System update:
The System update screen on a non-connected TV gives you the opportunity to connect your TV to the Internet to
automatically update your TV. We recommend this option if it is possible in your situation. To proceed, select Connect to the
Internet and follow the instructions in
Otherwise, if you can't connect to the Internet, select I can't connect, and then follow the instructions on the screen. Here's a
summary:
1. On an Internet-connected computer, go to the web site displayed on the System
update screen.
2. On the USB Update web page, select the correct TV model and then click
Download. Save the file to the root folder of a standard USB flash drive.
3. When the download finished, take the USB flash drive to the TV and plug it into the
USB port. When you do, the TV validates the files on the flash drive and displays a
12-digit code.
4. Write down the code and the web address, and take this information back to your
Internet-connected computer.
5. On the 12-digit code page, enter the code your TV displayed, and then click Next.
6. On the 6-digit code page, write down the 6-digit code that appears, and then take it
back to your TV.
7. Using the TV remote control, select Next to move to the next screen, and then use
the on-screen keyboard to enter the 6-digit code. When finished, select OK. The
system update begins. Do not remove the USB flash drive until the TV restarts.
When the update finishes, the TV restarts. You can check the new version number by
navigating to Settings > System > About.

USB flash drive
Any normal USB flash drive will
work, provided it has a FAT-16 or
FAT-32 file system format. (This is
the default for most flash drives.)
The size of the download is small—
usually less than 100 MB—and so
will fit on any size flash drive you
might have.
12- and 6-digit codes
The USB update process uses
a pair of codes to validate that
you are authorized to install an
update, and to ensure you are
not attempting to install an old,
unsupported version of the system
software.
