Disklavier

Hi All,

I own a Disklavier MX-100A. Bought it end 1989, so it is almost an Old 
Timer.
It has worked fine, until recently. I've a problem, only when recording. 
It seems that for one special key (middle A-flat) the pressing is 
recorded, but NOT THE RELEASE OF THE KEY. As a result, when playing that 
recording, this particular key goes down when first used in that 
recording (that's OK of course), but never goes up until the recording 
ends. So if this note is used in the composition again, it doesn't 
sound, because the key is still down.
This does not happen when playing older recordings, or recordings from 
other sources. And I checked all keys, but only one shows this behavior.
Any thoughts about cause, and possible solution?
Greetings, Leon (Netherlands)

It sounds like the metal flag in the bottom of the problem key has
fallen out. If that happens, the note ON is recorded but the key never
generates a note off when the key is released.

Thank you Bill, your answer was most helpful. The metal flag in the 
bottom of the problem key turned out to be on its place, but ... I 
noticed that a small piece of paper had fallen into the slot where the 
metal flag fits in, and that snip blocked the electric eye. As a result, 
the release of the key was not recorded.
By the way, I was surprised about the amount of dirt I found under the 
keys. Some cleaning there from time to time can prevent things like this.
Thanks again for your response,
greetings,

Hello Leon,

I am glad to hear that the piano is now working as it should be. It is amazing how much dust and debris can collect below the keys of a piano.
