Casio PX 830 strange spiking key Pleas help!

[bumplum]

Hi fellows. My Casio Privia PX 830 has a randomly spiking middle E note. Sometimes it plays fine and sometimes it goes to the highest volume setting when pressed regularly.  Please let me know if anybody else experienced this and if there is a fix.  Help!

Try blowing between the keys from both sides of the key until it returns to normal.  It usually doesn't take much air to fix it.  If air fails, the keyboard will need servicing.

Thanks, will try that!

I have the same problem with just one note: the same happened some years back - a single different note then - while my PX-330 was still under warranty, and so it got repaired under warranty, but of course, now it is no longer under warranty and we are stuck in semi-lockdown. so it's difficult to take the keyboard anywhere or get someone in to repair it! How would you suggest "blowing air"? On another thread it was suggested it should be compressed air. Would, for example, a hair dryer on cold, fastest setting do the trick? Or would it need the sort of pressure used for blowing up car tyres? Happy to try anything that might work without causing any further damage.

Compressed gas, otherwise known as a can of air from the computer section of a store is good to use; sold for cleaning computer keyboards and such.  You could also simply blow between the keys yourself.  I've personally had that work for me.  It doesn't take much sometimes.

Thanks: will try either or both forms of blowing!

Try to avoid anyone seeing you blowing between the keys as no explanation seems adequate.
