C key is sunken down. The hammer action counterbalance isn't working properly
I have a Casio Privia Px-150. The C key is sunken down compared to the other keys, it is still able to play, but it doesn't move as much as the others. I took the keyboard apart and found out that the hammer isn't as bouncy as the others, namely it gets stuck, so it seems like the hammer action isn't counter balancing properly. How should I fix this?

Check it again. It may have something dragging on the key, maybe something sticky like soda or juice residue. You can also try swapping out the key with another C or F key that is less used. Good luck!
