Question about Yamaha NP 30 76 Key Lightweight Digital Grand Piano with Touch Response
Some keys don't work at all (two); several keys must be played quite firmly in order to work. This occurs across all voices.
Oh, and one key sticks.
1) what causes this
2) who is my best bet for a correct fix - electronics specialist, music store, ???
3) who can likely fix it right, for the least $$$ (I'm broke)
It's not really for the faint of heart, but generally this is caused by gunk getting into the key circutry. Underlying the 3000's keyboard is a silicone pad with 2 contacts on it, the measurement between each being hit is the issue usually but yours just sounds like there's something in there causing a physical or contact obstruction.
What you really want to do is to remove the keys and clean everything but this isn't easy... You could try using 99% alcohol (from a pharmacy) to clean inside it which may well help you.
There's a good thread on a similar issue at:
Which may help you work out how to do the disassembly if you are brave, but I would start with pouring some alcohol in and poking it and hoping for the best 1st. It sounds crude, but it works amazingly well with some things.
