Single note (F#) does not sustain when the key is held down
(Los Angeles, CA, USA)
When I press the first F# to the right of middle C, and hold it down, I don't hear much sound, just an initial note then fades immediately. Whereas, other keys when pressed and held down lets the note sustain. I was wondering if this is a problem that could be resolved with adjustments or something needs to be cleaned internally.
