Our take on the Samsung BN94-18351W Main Board

This is the main board (the set's control board) for the Samsung QN77S90DAFXZA, a 77-inch LED TV. It carries Samsung part number BN94-18351W and cross-references board numbers BN97-21185J and BN41-03144A. It is a repair part, not an upgrade: it restores a dead or faulty set rather than adding features. Buyers should match all three numbers before ordering, since Samsung uses different boards across sizes and model years.

  • No instructions included; installation needs board-level repair experience
  • A wrong diagnosis wastes the part, since a faulty panel or power supply shows similar symptoms
