Hi ...
There are flexible cables that connect the keys to the main electronics. The connectors for those cables sometimes age poorly..
It is fixable. But dont "get taken" on a repair.
If it's just resoldering a few points,it shouldnt be more than $100.00
to fix

Either the keyboard is disconnected or the Keyscan on the keyboard itself is but. More than likely a loose connector.
SOURCE: Is there a Yamaha school
Yamaha prefers to MAKE the instruments rather than conducting repair schools... they may have some very specialized schools for individual types when first introduced. With the situation in Japan right now such classes would be cancelled I am sure. Instrument repair is so specialized other than basic piano repair/tuning that you will find few if any courses. For piano repair you might want to search YouTube for videos. For organs and keyboards, detailed electronic knowledge and the service manuals are what we have to work with. You need both experience in digital and analog plus test equipment including oscilloscopes and signal generators as a start.
