When a faulty power supply has been confirmed, replacement may address:

Fitment & Ordering Guidelines

Verify BN44-00947J on the original board's white barcode sticker. Compare any PCB/board number on your original unit, connector layout, full TV model suffix, and version before purchasing. Model name or screen size alone is not enough to confirm fitment. No substitute part number is supplied in this listing.

Unplug the TV before service. Power-supply capacitors can retain hazardous voltage after unplugging. Use a qualified technician if you are not trained in safe TV repair, follow ESD precautions, and handle the board by its edges.
