Defective key on PXS3000, stuck on full volume.

Hi all, my E4 key just today started having a problem where it will play MUCH louder than I am playing it, for anything over a mezzopiano it will play full volume.  I can get it to play softer if I go pianissimo but it is definitely defective.  Tried tuning the keyboard off and on again, tried unplugging it and plugging back in, even tried turning it upside down and shaking it a little bit.  Just throwing shots in the dark at this point.  Is this an issue others have had; and does it require a professional repair?

 

Thanks.

One of the sensors on the key has an issue, perhaps just dirty or stuck.  Try blowing air between the keys.  Try it from both sides and a few angles.  It may help.  If not, it will need servicing.

Just to say that I came here looking to see if anyone else was experiencing this.

A few months after the 3-year guarantee expired, and this is happening to multiple keys on the keyboard. The velocity sensor seems to have gone kaput.

I've only used the keyboard lightly, and it sits in a corner of the room and never travels.

A bit disappointed, TBH....

Have you tried the air solution?  Did anything spill on the keys? If it's random keys, the sensors are most likely dirty or stuck and cleaning would fix it.

Hi Brad,

I did try blowing, but it didn't achieve anything.

I'll try buy a can of compressed air, that might be better.

Would you recommend taking the keyboard apart myself and trying to clean the contacts, or is that too risky?

Thanks!

It's probably best for someone with experience to disassemble it.  It's possible to damage things inside.
