Reference: b-LAN Setup & Overview
The b-LAN module is internal to the TV. It allows hotel/institution head end equipment with b-LAN technology to communicate, via the institution’s RF distribution system, with the TV for configuration and control.
Installer Menu item 118 POWER SAVINGS controls the power circuitry for both the embedded b-LAN module and the GAME CONTROL/MPI port. The default value is 003—the b-LAN module is only powered when the TV is turned ON. See chart below.

A b-LAN enabled head end device, such as an LG FMA-LG101, broadcasts over the RF distribution system to communicate to multiple TVs. When the TV is first installed, it must be turned ON in order for its embedded b-LAN module to receive communication from the head end device. At this point, if it is desired for the b-LAN module to always be powered, including while the TV is in Standby, set Installer Menu item 118 POWER SAVINGS to 001.
Also, if MPI communication is required for external MPI control, set Installer Menu item 118 POWER SAVINGS to 001 so that the GAME CONTROL/MPI port circuitry is always powered.
LT670H TVs only: For specific applications, the RS-232 (DB9) port may be used to provide +12v/1A external power (for example, to an external MPI control device). In this case, Installer Menu item 118 POWER SAVINGS must be set to 009—both the b-LAN module and the GAME CONTROL/MPI port circuitry are always powered, and the external power is provided on pin 9 of the RS-232 port.
Caution: POWER SAVINGS should NEVER be set to 007. This setting is intended for factory use only.
