You can check for guide rail bushing friction but my first guess would be that damper lever hanging on the sostenuto bar. dp __________________________ David M.

A medium hit on the key seems to jam the hammer for 1 second but it returns to the down position. Even if I hit the key lightly I observed some binging of the damper before it returned to the down position. What could be the problem, does the action have to be taken out of the piano for repair?
