Samsung bn44-00423a Tv Dc Vss-pd Power Supply Board

Product Description

The SAMSUNG bn44-00423a is a DC VSS-PD power supply board designed for use in Samsung televisions. This board converts incoming AC power into the stable DC voltages required to drive video processing circuits, display panels, and internal control circuitry. It mounts inside the television cabinet and interfaces with the main board and display assembly via a wiring harness. When correctly installed, it provides regulated power delivery, protects downstream components from electrical variations, and supports consistent system operation. Licensed electronics technicians and experienced service personnel are the typical installers of this component.

This power supply board is suited for television repair and service applications where the original board has failed due to power surge damage, component failure, or age-related degradation. It serves as a direct replacement for the factory-installed unit in compatible Samsung TV models. The board supports the core functions of video processing and display operation by maintaining stable DC output across system loads.

Key Features

• Converts AC input to regulated DC voltages for TV subsystems
• Supports video processing, display panel operation, and internal circuitry
• Connects to main board and display assembly via wiring harness
• Provides protection against electrical variations and voltage instability
• OEM-style replacement for factory-installed power supply board

Compatibility

Designed as an OEM-style replacement power supply board for compatible Samsung television models. Confirm compatibility with the specific TV model number before ordering.

Installation Notes

Installation should be performed by a qualified electronics technician familiar with television service procedures. Disconnect the television from mains power and allow capacitors to discharge fully before handling any internal components. Discharge is critical on power supply boards, which can retain hazardous voltage levels after power is removed. Follow all applicable electrical safety standards and the TV manufacturer service documentation when reconnecting the wiring harness and securing the board.
