Why dont my pedals work??

by Alyson
(London Ontario Canada)

I have a Yamaha Clavinova CLP-220. I have had it for approximatley 4 years, but for 3 of those years I have been trying to fix my pedal. 0 out of the 3 pedals work. Damper, Sustain, and Soft. On a very rare occasion the sustain will work for only one key, but once I let the pedal go I dont get it back for the same key or any of them for that matter. I have taken it apart to take a look at it, and there doesnt seem to be anything wrong, nothing appears to be missing or disconnected or broken. If someone could help me with my problem it would be greatly appreciated.

Hi Alyson,

I am not familiar with you Kboard but if there is a cable connection I would have a look at the place where it goes into the Kboard itself, plug or direct connection, it is quite often the place for problems.
Hope this helps.

TRy rebooting. Turn off piano, hold down 88th key and start. I had to do it a few times. 2 out of three started working. Sustainer still not working. Hope that helps

Clavinoa Sustain pedal

Hi. Just had my clavy 153s sustain pedal fixed. The wire to the pedal was the culprit. Good luck with yours.

Pedal problem on Clavinova
by: Dan Redhead

As suggested it could be the PK cable - between base of keyboard and pedal unit. Very rarely it can be caused by the socked this plugs into on the PCB inside the piano.

The PK cable also fits under the pedal unit by way of a small IDS push in plug. I have known this to work loose if the keyboard is moved around and caught of carpet for example.

Check security of plugs at both ends of the cable.

If nothing is working then the above would be the most likely cause. If only part of the pedal eg sustain is not working then inside the pedal assembly is a rubber dome with a carbon switch. This can wear out or get dirt inside but this woulod normally only happen to one part of the pedal.

I hope that helps.

Sounds simple, but we found the sustain always on, regardless of action on the pedals. This page suggested to check the cable connection from the pedals that I'd forgotten even existed. Reconnected the cable and the problem was solved.
