Disklavier

The Silent Mode, when activated, can only be heard through headphones.  The 
volume control knob next to the Silent mode switch, however, needs to be 
turned up to hear the speakers when the piano is playing a floppy disk or CD 
that has ensemble sounds.

Underneath the piano, next to the pedal lyre, is a large, round connector 
with lots of pins.  It goes from the pedal lyre to the underside of the 
piano.  GENTLY see if that round connector turns.  It should NOT!  Only the 
collar that tightens the connector should turn.  If the connector itself 
turns, you have a problem. What can happen is that the piano movers try to 
turn the connector.  It should be put in place, without turning, and only 
the collar should be tightened gently by hand.

The other tricky connector that is sometimes overlooked is on the UNDERSIDE 
of the keyframe.  A piano technician would remove the control box to the 
DKV, remove the fallboard, remove the keyblocks on either side of the piano 
action and pull the piano action out about 3/4 of the way out of the piano.  
Then lift up the front of the action in order to see the underside of the 
piano keys.  Although that connector may look connnected, I have found on 
several occasions that it is at a slight angle.  Hopefully this is the 
problem.

The simple solution already mentioned, is to remove the fallboard by lifting 
it straight up, and check that the gray cable on the right is connected to 
the side of the piano.  HOwever, when this situation occurs the error reads 
Sensor Not Connected.

I am assuming you bought this piano from your local Yamaha dealer so a 
technician should be available. Call them.
