The only way to solve it is to either replace everything or pull everything out and repin. It might also be good to rinse out the bushings with something. Acetone? I'm not sure. Avery <blockquote type=cite class=cite cite="">  But, I know you don't want to hear it, but, if you had a problem with one or two notes, I could bet the problem will come back to haunt you on other notes. It is sometimes the longer road that brings the best result. Some of these pianos had plating problems with the center pins and there is only one solution:  repinning.
