• Unresponsive TV controls or input problems diagnosed as a main-board fault.

Fitment & Ordering Guidelines

Verify BN96-56550K on the white part-number sticker, compare the PCB/board number on your original assembly, and match the full TV model suffix and version code above. A matching screen size or similar-looking board alone does not confirm fitment.

Disconnect the TV from power before servicing. Power-supply components can retain hazardous voltage; installation should be performed by a qualified technician using proper ESD precautions. Handle the board by its edges and avoid touching connectors or components.
