Fitment & Ordering Guidelines

Verify EAY65920741 against the white-sticker part number on your original power supply. Compare the PCB/board number, connectors, full TV model suffix, and version code. A matching TV model alone does not guarantee compatibility; no additional versions or substitute parts are confirmed in this listing.
