Anitas posted a topic in Privia x50 x60 SeriesI have a Casio privia px-350M, and a key popped up (raised higher)! I disassembled the piano by taking all the screws I could find out. I know the problem, I have to hope a white square piece to a black lever, but don't know how. I NEED HELP ASAP AND DONT HAVE WARRANTY, this piano was very expensive. In desperate need.
