I have a P200 Digital Piano that has a sticky Key. It was manufactured in 1998, but has never left the house and had limited use. But my great granddaughter stared using it for lessons and that is how the sticky key was found. I have seen postings about a Service Bulletin 1468 1/3 that references a defect in the P200. I asked Yamaha about it, but they just answered to say they would provide a discount on a ne keyboard assembly (a $1031.00 Part). That is not workable for me because I have extensive bills getting my dog cancer surgery. If I knew it was part of that service bulletin, I would go after them. Else I will live with the sticky key.
