LG Electronics 26LT670H, 32LT670H, 37LT670H, 42LT670H, 55LS675H Reference: Restoring Factory Defaults on the TV(s)

56 206-4213

This section describes how to restore 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.

Note: If the TV(s) is/are currently in FTG Mode, restoring the factory defaults also resets the TV to Pass-

through Mode.

If the TV is currently in Pass-through Mode, you can set Installer Menu item 117 FACT DEFAULT to 001

to restore the factory defaults and clear the channel lineup, including any assigned channel icons and

custom text labels.

If the TV is currently in FTG Mode, a predened value for Installer Menu item 117 FACT DEFAULT

enables access to initiate a factory “IN-STOP” process that will restore the TV to Pass-through Mode in

addition to restoring all factory defaults. Contact technical support for the required value for Installer Menu

item 117 and for additional information on performing the IN-STOP from the Installer Menu.

There are two additional options for restoring Pass-through Mode/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 Conguration (.tlx) le, i.e., an FTG Conguration le with no

data. Refer to the Free-To-Guest (FTG) File Manager User Guide for further information.

• Using a USB memory device, “Teach” a “Zero Mapped Channels” FTG Conguration (.tlx) le to the TV.

Refer to “Teaching FTG Conguration to a TV” on page 41 of this document for further information on the

Teaching process.

• If your system uses a Pro:Centric server for remote management/administration, use the Pro:Centric

server Admin Client to load a “Zero Mapped Channels” FTG Conguration (.tlx) le on the Pro:Centric

server. Refer to the Pro:Centric Server Admin Client User Guide for further information.

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. Refer to the “FTG Mode via EBL” procedure on page 44 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 conguration, congure the FMA

device with an FMA Conguration (.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 & Conguration Guide for the FMA device for further information.
