Important Compatibility Notice

Before ordering, please confirm that BN44-00874C is printed directly on your original board. Samsung often uses multiple board versions within the same TV model series. Matching the TV model alone is not sufficient. The board number must match exactly.

To verify compatibility:

• Remove the back cover of your TV
• Locate the white barcode sticker on the power board
• Confirm the part number reads BN44-00874C

If the number does not match exactly, this board will not be compatible.

Why Replace the Power Supply Board?

The power supply board converts AC wall power into regulated DC voltage required by your TV’s internal components. When it fails, the TV cannot properly initialize or maintain stable operation. Replacing this board is often more cost-effective than replacing the entire television.

Installation Notes

• Professional installation is recommended
• Disconnect TV from power before servicing
• Handle internal components carefully to avoid static damage
