WD My Book World Circuit Board

My 3 year old WD My Book World will not power up. It tries to for about 5 seconds and then shuts off. No blue lights, no spin, nada. Thinking about installing a new circuit board.  Does anyone know where to go to order replacement parts. Particularly a circuit board.

Hello, you can first try getting a replacement power cable by calling tech support. If that doesn’t help you can start searching for replacement parts on Ebay, but I don’t know if that works.
