Hi @tgoodm1

The best way to ensure that you're getting the correct parts is to search online for the part number.

According to the service manual for your model, the backlighting is provided by a CCFL tube (cold cathode fluorescent tube) and not LED strips, so it may be a problem with the inverter board in the TV or perhaps the tube itself.
