Upgrading TV/PTC Software

Before you begin, note that the software upgrade les must be stored in a folder
named “LG_DTV” in the root directory of the USB memory device. Also, ensure
the USB device has been formatted with FAT format.
Note for TV Software Upgrade only: If the TV detects a later version of software
on the USB device, it will automatically display a dialog from which you can start the
software upgrade immediately. Otherwise, you can close the dialog, and access the
USB Download Menu as described below.
1. Turn ON the TV, and then plug the USB memory device into the USB IN port
on the TV.
2.
Press MENU SETTINGS on the Installer Remote to display the TV setup
menus (TV is in Pass-through Mode) or the Function Menu (TV is not in Pass-
through Mode).
3. Use the arrow navigation keys to select/highlight either the Option menu icon from
the TV setup menus or the Lock menu icon from the Function Menu. Then, press
the number “7 key a total of seven times to display the USB Download Menu.
4. Use the Up/Down arrow keys to select Upgrade TV Software or Upgrade
PTC Software, as applicable, and press OK.
5. Select the appropriate option(s), depending on the type of upgrade:
• TV Software Upgrade: (See screen samples at right.) Select TV Software
Update from the rst TV Software Update window. In the second TV Software
