Samsung bn44-01104b Tv Dc Vss Power Supply Board

Product Description

The SAMSUNG bn44-01104b is a DC VSS PD power supply board designed for use in Samsung flat-panel televisions. This board converts incoming AC line voltage to regulated DC outputs, distributing power to the mainboard, backlight inverter circuit, and other internal components. It plays a central role in maintaining stable voltage across the display system. Failure of this board typically results in a no-power condition, cycling power, or backlight shutoff. Replacement is performed by qualified electronics service technicians with appropriate ESD precautions.

This board is intended for use in Samsung flat-panel televisions where the original DC VSS PD board has failed or is producing irregular voltage output. Common symptoms that indicate a failed power supply board include the television failing to power on, shutting down unexpectedly, or displaying a blinking standby LED without reaching full operation. This is an OEM-style replacement part suited for depot-level or in-home TV repair service.
