Help with Silent Piano

[Mgrove]

Three Weeks ago I had a Yamaha U3 Silent Piano delivered to my home.  It is a used model, about six years old and made for the Japanese market.  The acoustic part of the piano is fine. However, when I use the electronic keyboard, I have found the response to be horrible.  

The volume of the keys fluctuate and it is not any one particular key.  I can be playing a piece and hit a note that is so very loud that it really hurts my ears.  I really don't think that it working appropriately and the dealer had informed that there was not a warrenty associated with the Midi.  I have not yet contacted him about this but will today.  Any advice? Has anyone experienced this problem?  I have also noted that one key doesn't even play electronically.  

I did test this out before I purchased it in the showroom, but really didn't notice these problems until the first time I sat down to play it in my home.

Thanks for any input!

interesting....  maybe you should contact the manufacturer?

It seems a bit fishy to my that there would not be a warranty with the midi system.  The whole piano should've come with a warranty.  Definately call the manufacturer and see if you can speak to a manager where you bought the piano.  Something there just doesn't sound right.
