What David Love said. But first try lifting and leveling 
strings at the capo. If none of this works, don't waste new 
hammers on a dead soundboard.

Kawai boards are, depending on who you talk to, rib crowned 
but largely panel compression supported. In this case, I 
expect the soundboard is the likely problem.
