Samsung bn44-00775a Tv Power Supply Board

Product Description

The SAMSUNG bn44-00775a is an OEM-style replacement power supply board designed for Samsung flat-panel televisions. The board regulates and distributes stable DC voltage to the television's internal circuits, including the main board, backlight inverter, and panel components. A failed power supply board typically presents as a TV that will not power on, shuts down unexpectedly, or displays standby indicator behavior with no picture. This board restores proper power delivery to the set and is installed by electronics repair technicians as part of a component-level TV repair.

This power supply board is intended for use in Samsung flat-panel televisions as a direct board-level replacement. It is suited for component-level repair shops, in-warranty depot service, and out-of-warranty consumer electronics repair. Technicians typically install this board when diagnostic testing confirms the power supply stage is at fault rather than the main board, panel, or T-con board.

Compatibility

Designed as an OEM-style replacement power supply board for compatible Samsung flat-panel television models. Verify the board part number printed on the original installed board matches bn44-00775a before ordering, as Samsung televisions may use multiple board variants within the same model line.

Installation Notes

Power supply board replacement should be performed by a qualified electronics technician. Disconnect the television from AC power and allow capacitors to fully discharge before opening the chassis — power supply boards retain high-voltage charge after power is removed. Use appropriate ESD precautions when handling the board, and disconnect all ribbon cables and harness connectors carefully before removing the original board. Reconnect all connectors fully and verify seating before powering the set for the first time after installation.
