I serviced a Steinway grand that had let-off problems. I searched and searched until I found it. The jacks were assembled in two pieces - the tender "arm" was glued to the jack (or fly). The glue was failing on several of those jack assemblies, thus allowing the tender "arm" to move a little bit every time the tender contacted the regulating button. It was really weird at first, because I would adjust the let-off, play the key a few times, and the let-off would change. Once I reglued the tenders to the jacks everything was fine and adjustable once again. I don't even know if the subject Yamaha of this riddle even has these kind of jack assemblies, but I thought I'd throw this out there.
