From looking at the service manual, I can tell you that Yamaha’s internal name for the board is “YC405D0” while the part number is “WU045000”. Rather than “motherboard”, these Motif main boards are usually termed the “DM board” or “main PCB” from what I have seen. These identifiers and terms might help a bit in searching for one for purchase.

Unfortunately I’m not seeing anything available from a quick web search of my own: not even an out-of-stock listing for $1,013.30 like you’ll find in a search for the XS’s main board.

Did they give you any more information about any specific component on the board that had failed, or suspected causes? Also, was it an authorized Yamaha service center that you spoke with?
