bumplum Posted July 21, 2017 Share Posted July 21, 2017 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!

Brad Saucier Posted July 22, 2017 Share Posted July 22, 2017 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. Quote Link to comment Share on other sites More sharing options...

Trish S Posted March 20, 2021 Share Posted March 20, 2021 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.

Brad Saucier Posted March 20, 2021 Share Posted March 20, 2021 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. Quote Link to comment Share on other sites More sharing options...
Trish S Posted March 24, 2021 Share Posted March 24, 2021 Thanks: will try either or both forms of blowing! Quote Link to comment Share on other sites More sharing options...
IanB Posted March 24, 2021 Share Posted March 24, 2021 Try to avoid anyone seeing you blowing between the keys as no explanation seems adequate. Quote Link to comment Share on other sites More sharing options...
