Hello,
We have a Yamaha YDP-121 piano that last year started having some keys stuck down when pressed, but after a few months practicing, more keys are showing this problem. All keys sound, but they don’t come back upon their own.
It seems to be an issue with this model for what I see, but the closes repair center to where we live is mode than 100 miles away. I was wondering if someone has an idea of what the problem might be, if it might be somehow easy to fix. I am an electrical technician, but I am not familiar with pianos.
Opinions, recommendations and/or guidance are appreciated.
Thank you.
