I have a CVP-107 digital piano with keys that are getting harder to press to get a sound out of it. It's been like this for over a year now, and a few of the keys are rising slower than the rest. I'd love to here some feedback on how to fix this problem.

I consulted a piano tech and they confirmed that there is no repair for such cases since the material for the keys is plastic unless it's metal. though i am not 100% convinced hahaha coz they recommended buying a new one instead.. like watdafffff grrrrrrr

I have a similar issue, not getting the key sticky, but if I play a key repeated times, in combination with other, it becomes harder to press it. I searched on web about this issue, but have not found any solutions or similar situations except this above comment. If anybody has a clue, please advice! Thanks

HI,
the problem is with the key itself, with geometry. During time key become twisted shape. Hard to notice and very tricky to change with new one. Lubrication does not help. Yamaha is only manufacturer I know where those keys bending by itself.
