Check the firmware version

Your firmware may already be up to date, especially if you have a new AV Receiver. If the version number is M35.R.2197 or higher, you do not need to update.

If you're not sure, it's easy to check which version of firmware you have:

1. Turn on your TV and check it's tuned to the input your AV Receiver is connected to. If the AV Receiver is connected to the HDMI2 socket, choose HDMI2 as the input.
2. Turn on the AV Receiver.
3. Press HOME on the remote control and wait until you see the home screen.
4. Select Setup → System Settings → System Information using the remote control arrow buttons, and press ENTER.
5. On the TV screen, the firmware version number looks like this:
   Software Version M35.R.2197 - if the version number is M35.R.2197 or higher, you already have the most recent firmware version.
