Dampers on P-22

[mps@usol.com]

I have a Yamaha P-22 with a damper problem.

I have isolated where the problem is and it is because the felt does 
not contact all three strings. So this note rings on after being struck.

Is it better to replace the entire damper (block & all) or just put on 
new felt?

P.S. This is a 6 month old piano

Thank you
