This section describes how to restore all factory defaults or just the Installer Menu factory defaults either on a
single TV that is currently in Pass-through or FTG Mode or on multiple TVs that are currently in FTG Mode.
Restore All Factory Defaults
This section describes how to restore a single TV, regardless of its mode, to a factory default condition.
The following procedure requires that you contact LG technical support to obtain a predened value/
password for Installer Menu item 117 FACT DEFAULT that enables access to initiate a factory “IN-STOP”
process, which restores all factory defaults. This procedure will also reactivate the EZ-Manager Wizard.
1. Use the Installer Remote to access the TV’s Installer Menu.
2. Navigate to Installer Menu item 117 FACT DEFAULT, and key in the value provided by technical support.
Then, press OK.
3. At the prompt for conrmation, key in the password provided by technical support. This will initiate the
IN-STOP that restores the factory defaults on the TV.
Installer Menu Item 117 FACT DEFAULT
If the TV is currently in Pass-through Mode, you can set Installer Menu item 117 FACT DEFAULT to 1 to
restore the Installer Menu factory defaults and clear the PTC Channel Map, including any assigned channel
icons and custom text labels. Note, however, that if a complete restoration of the TV’s factory defaults is
required, see “Restore All Factory Defaults” above.
Additional FTG Mode via CPU Options
There are two additional options for restoring Pass-through Mode/Installer Menu factory defaults on TVs that
are in FTG Mode via the CPU. The rst enables you to restore a single TV to Pass-through Mode, while the
second enables you to restore multiple TVs to Pass-through Mode at one time. However, both options require
that you create a “Zero Mapped Channels” FTG Conguration (.tlx) le, i.e., an FTG Conguration le with no
data. Refer to the Free-To-Guest (FTG) File Manager User Guide for further information.
• Using a USB memory device, import a “Zero Mapped Channels” FTG Conguration (.tlx) le to the TV. Refer
to “Importing a Clone File” on pages 44 to 46 for further information on the import procedure.
• If your system uses a Pro:Centric server for remote management, use the Pro:Centric server Admin
Client to load a “Zero Mapped Channels” FTG Conguration (.tlx) le on the Pro:Centric server. Refer to
the Pro:Centric Server Admin Client User Guide for further information.
Additional FTG Mode via EBL Options
There are two additional options for restoring Pass-through Mode/factory defaults on TVs that are in FTG
Mode via the EBL. The rst enables you to restore a single TV to Pass-through Mode, while the second
enables you to restore multiple TVs to Pass-through Mode at one time.
Note: While the IN-STOP process described above will clear both the PTC and the CPU, both
options below only clear the PTC. Thus, the current Channel Map and TV setup menu settings
will remain in the CPU after the reset is completed.
• Using a direct PC-to-TV connection, “Write” an unpopulated Channel Map—that is, a Channel Map with 0
(zero) channels—to the TV. See Reference section, “FTG Mode via EBL (Local Conguration),” and/or the
Free-To-Guest (FTG) Device Configuration Application User Guide for further information.
• If your system uses an FMA for remote management/broadcast conguration, congure the FMA device
with an FMA Conguration (.fma) le that only contains a “0 Mapped Channels” FTG Channel Map to
broadcast to the TV EBL(s). Refer to the Free-To-Guest (FTG) Device Configuration Application User
Guide and/or the Installation & Conguration Guide for the FMA device for further information.
