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.</FONT></SPAN></DIV> <DIV><SPAN class=375221020-16052006><FONT face=Arial size=2></FONT></SPAN> </DIV> <DIV><SPAN class=375221020-16052006><FONT face=Arial size=2>What could be the problem, does the action have to be taken out of the piano for repair?</FONT></SPAN></DIV> <DIV><SPAN class=375221020-16052006><FONT face=Arial size=2></FONT></SPAN> </DIV> <DIV><SPAN class=375221020-16052006><FONT face=Arial size=2>Thanks,</FONT></SPAN></DIV> <DIV><SPAN class=375221020-16052006><FONT face=Arial size=2></FONT></SPAN> </DIV> <DIV><SPAN class=375221020-16052006><FONT face=Arial size=2>Marc</FONT></SPAN></DIV></DIV></BODY></HTML>
