Disklavier

I have a bad solenoid. It won't play during post install test. When in quiet mode you have to hit the key hard to get any sound...

I was wondering if there is a way to clean these and check them other than just the post installation check routing in the PRC.

I think I am still under warranty, 4 year old Piano. 

Thanks in advance.

Hi Jim,

You stated that when in Quiet mode you have to hit the key to get any sound.

Are you talking about when YOU play the piano or when the Disklavier is playing the piano?

If you are talking about when YOU are playing the piano, the problem is not the solenoid, it is the sensor for that note.

To confirm, record a song playing each key from lowest note to highest note. Play the song back and note which key(s) do not playback.

Then, play back the song again, with the piano transposed up or down a couple of steps. Now watch what solenoids do not playback. 

If the SAME keys do not play back during both song playbacks, the problem is the solenoid. If DIFFERENT keys do not play back, the problem is related to the sensors. 

Let me know what you find.

Thanks for getting back to me.

Both of these things are happening with this key. The piano will not play the note AND when you are in quiet mode and you play the note it is super quiet compared to the other notes. I assumed the sensor and the solenoid were integrated so whatever is happening is effecting the solenoid and the sensor.

I ran the Post Delivery Test (Key Scaling) and it skipped the key every time (two day ago). Then I went and ran it again (tonight) and it worked. So for now it seems to be working.... Hopefully this will stay corrected. 

FYI I have a Mark IV

Thanks for all the help.

Hi Jim,

I am glad to hear that it played OK tonight but am not confident that your piano's problems have been solved.

Were you able to perform the record/playback test I suggested in my last email? If so, can you let me know the results when you transposed the playback?

Having both a sensor problem and a solenoid problem on the same key just isn't likely. They are not integrated in that way.
