Samsung bn44-00948d Led Tv Power Supply Board

Product Description

The SAMSUNG bn44-00948d is a DC VSS power supply board designed for use in large-format LED televisions. This board converts incoming AC line voltage into the regulated DC voltages required by the backlight driver circuit, main control board, and signal processing sections of the set. It mounts inside the television chassis as a self-contained power module and is the central component responsible for voltage distribution during startup and continuous operation. Licensed electronics technicians and TV repair shops typically service and replace this board.

This power board is identified by the assembly reference L82Q8NA NSM and is intended for use in Samsung LED televisions that use the BN44-00948D power supply configuration. It supports the electrical requirements of the display panel backlight along with the logic and processing circuits that govern picture, sound, and smart-platform functions. It is suited for depot-level or bench repair of affected television units.
