This is a used board pulled from a TV with a broken screen then tested in a working one of the same model. It is guaranteed to be 100% functional. Please verify all numbers prior to purchasing. This set uses several different versions of boards that may look very similar. Look for 75500C010001 on the white sticker on your current board to ensure compatibility. Please consider sending me a message prior to purchasing if you are unsure on which part you might need to complete your repair. I’d rather help troubleshoot up front so you can rest assured that you will be receiving the part that you need to get your TV running properly again. Thanks in advance for your business and I look forward to assisting with your repair!
