For now, I have given up on trying to make the DKC850 work with my piano, so
I am back to the 100R.

 

But now (and this might have been a big part of the problem in trying to run
the 850 through the 100R, per my Yahama dealer's suggestion), it plays for a
couple of minutes then a message appears on the display as the music stops
that says:

 

Piano Power Off!  (01:55)

(PWM OVER)  _  ESBL

 

That is pretty much verbatim.  The guy that came out from the Yamaha dealer
(*NOT* a disklavier tech) said that it sounds like there is a problem in the
power circuitry INSIDE THE PIANO, as opposed to inside the 100R.

 

Can anyone clarify or make suggestions?

It sounds like a power supply problem. You probably need a new one.

Power supply in the piano, not the control unit itself.

Not DKV exactly, but I'm curious about this: My brother (who gave me one of his DKVs), bought an NU1 last year. He told me it was out of tune when he got it - which seemed impossible to me as its a sampled piano with an acoustic action. He has perfect pitch, so I assumed he was just super-sensitive to non-perfect samples.

Yamaha sent a tech to his house, who said "the sensors were dirty", and repaired (cleaned?) them.My brother reports the piano now sounds totally different, pitch is perfect. 

My question - what do sensors have to do with pitch? I can see volume/velocity issues, but pitch? I'd appreciate any explanation or ideas.
