I am wondering what ideas or experience people have concerning the possible reasons a new Korean-made piano seems to be incapable of holding pitch. It's a 5'3" Samick-made grand. It was tuned prior to delivery in early September 08 (I assume it was; I didn't do it). When I gave it its post-delivery service in September it had slipped 30-40¢. I pitch-raised and tuned it. By December the customer was complaining; I made another service call and found the piano again 30-40¢ flat. I again double tuned it (using the RCT pitch raise function) and left it on pitch. I tuned the piano again in the beginning of June and found the bass about 25¢ flat, the midrange from 10-15¢ flat to on pitch, and the high treble 80¢ or more flat! It seems pretty obvious that something is moving around in there, a bad glue joint in the frame? an improperly secured plate? I don't have the luxury of going back and making measurements or poking around (I'm not being paid to do that), but I'm interested in what other technicians think may be going on with this piano. I've recommended to the store that sold the piano that it be replaced, but I'd like to have some possible technical points regarding the apparent failure in the structure of this piano to discuss.
