Yamaha CLP-230 touch sensitivity problem with keys

[biorox]

Hi all, I'm new here and don't know much about piano maintenance but was hoping for some advice.

We have a problem with our CLP-230 where several keys have partially lost touch sensitivity. i.e. during play they will occasionally sound out very loudly regardless of how you press them.
These also seem to be the keys that are most often used. The person who bought the piano was apparently told to not play it too much at low volumes (but not why), and they think that this may have caused the problem.

The piano is eight years old and we need to sell it, but in order to do that we first need to fix this issue. Is there any way this can be done? Would we have to call up a specialist, and what kind? Approx. how expensive would this be? We are in the Vancouver, BC area.

Thank you in advance.

Playing at low volume has nothing to do with it.

The problem is a fault with the rubber key switches under the keys. It only takes a little bit of dust or debris to cause the problem you're having.

Contact Yamaha online (or at their California office ... not sure if the latter is suitable since you're in Canada), and ask them to refer you to a local Yamaha trained repair shop.

I don't know what repair prices are like in Vancouver, but in my former home in south Florida and also here in North Carolina, you'd expect to pay between $100 and $200 for this repair.

And, since the unit will be disassembled for that repair work, have the technician lubricate the keys.  You'll need that sooner or later, so you might as well do it now.
