You can perform a manual check for updates with these steps:
  1. Press the "Settings" button on the remote.
  2. Choose the "All Settings" option at the bottom.
  3. Choose the General menu on the left. • Scroll down, and near the bottom of the list, select "About this TV."
  4. Make sure "Allow automatic updates" is checked, and click the "Check for updates" button.
  5. If an update is found, follow the steps on the screen to download and install it.
Note: LG TVs will automatically check to see whether new software is available for download whenever the TV is powered on, and randomly every 2-36 hours.
