Casio Privia PX 150 - 2 notes not sounding unless played very hard

[John H]

On my Casio Privia PX 150 - 2 notes not sounding unless they are played very hard. The notes are F and F# below middle C, and they are next to each other. I have cleaned the area on the circuit board under those two keys but that hasn't changed anything. As mentioned, the notes WILL SOUND if you strike the keys very hard. But they don't sound if you're playing at normal touch pressure.

Anyone else bumped into this issue, and if so do you have a repair solution or suggestion? I'm guessing someone spilled something along the way in this area of the keyboard, although looking at the circuit board there was nothing apparent. Hate to toss out an otherwise perfectly good Privia, but with those notes not working it's not very usable. Thanks in advance.

Hello John H

 

Ok, I understand you have cleaned your instrument - but have you tried this approach ? :
