Hello to all.
I have the Yamaha P95 piano and the first 3 G and the first 4 C# do not play.
She is 2 years old but she played very little, I also took it apart and cleaned it and it looks new.
any suggestions?
to repair or throw it away?
thank you

 

If single notes are not playing then you most likely have dirty key switches.
Clean gently with isopropyl alcohol.

 

Service manual is useless really,,, unless they are rubber keys on a PCB, that need cleaning as said, or individual switches that have a common feed that may be broken on the PCB trackside, you take the thing apart to find out...

 

You need to get at the switch contacts and clean the contacts with isopropyl alcohol on a cotton swab.

 

nothing dirty or broken. I think it's the mainboard. can you buy?

 

Best to meter out the key switches with an Ohmmeter or Dvm to test it first before you decide it's the main board..
