Disklavier

Yamaha dealers know who the local Disklavier technicians are.  The 
Disklavier is mostly serviced by piano technicians; sometimes the organ 
technician if the problem is in the amplifier.  Such is the nature of a 
hybrid instrument.

Most Disklavier technicians feel like the Maytag repair man.  There are very 
few things that ever go wrong with them.  Most of the time, the piano is 
adjusted - not the Disklavier!

Because the piano is a mechanical device, and subject to humidity changes in 
the wood parts, the geometry of the working parts can change slightly.  Felt 
bushings compress and screws can become loose.  This is why it is necessary 
from time to time to calibrate the "computer" to the condition of the piano. 
  However, the tolerances built into the Disklavier are so reasonable, that 
the piano has to be really out of kilter for the DKV to show error messages.

Any good piano technician can service a piano equipped with a Disklavier.  
The piano part is serviced like any other acoustic piano - except that one 
wire harness gets disconnected on DKV models with the Record feature.  
Play-0nly models seldom need special servicing.

The most common adjustment is the damper pedal - the far right one.  Piano 
technicians usually check this adjustment each time an instrument is tuned 
on pianos that don't have Disklaviers.  Because the DKV has an in-line pedal 
solenoid, special care needs to be taken to assure that the normal pedal 
adjustment leaves this solenoid in the proper operating position.  If there 
is a problem with the pedal solenoid, it will often heat up, but turn itself 
off before damage is done.  There will also be error messages indicating 
that the pedal needs adjusting.

Piano technicians seldom deliver and set up pianos - piano movers do this!  
Most dealers have a Disklavier technician thoroughly check over the units 
before delivery so it should only take the delivery people a few minutes to 
set it up.  Most of the Disklavier technicians I know are first rate piano 
technicians as well as concert quality tuners, and don't work cheap!  I am 
sure your local Yamaha dealer knows of one!
