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.

Pedals were unplugged
by: Brian Jasmer

My Yamaha Clavinova had an issue where the sustain was always active. Any key I pressed caused a sustain. Furthermore, the pedals did not work.

There are two connectors that connect the pedals to the piano. One is at the piano and one is on the pedals themselves. Turns out that one of them was not connected. I plugged the connector back in and everything works fine.

Turns out for these keyboards, if the pedals are not connected, the sustain is activated. So the pedals must be connected to the piano in order for the sustain to operate normally.

Dan Redhead, if you happen to see this, do you know if you can buy replacement rubber domes/carbon filters? I took my pedal unit apart to try and fix it, found one flipped inside out, fixed that, and it started working briefly. Then it quit working again. I am assuming it got flipped inside out again. Do you know what I could do to help keep it from doing this? Or if I can buy a replacement if that’s what’s needed? Thanks!

Check the easiest solution first
by: Rob

My family came to a care facility that had a beautiful, fairly new keyboard, but the pedals didn't work. Even though the wire connection from the pedals to the keyboard was obviously solid, I eventually unplugged it and put it back in. Worked like a charm! I do the same thing when a mouse doesn't work on a computer. Perhaps the system wasn't reading the connection properly. I do wonder if it would have worked just as well to unplug it for 5 minutes and then plug it back in.

Piano salesman suck
by: George

I have sustain issues with my clp 265gp..... this is an $8000. Dollar piano and Yamaha doesn't offer shit in the way of repair... I downloaded the repair Manuel and tried basic remedies.... yamaha, which makes fine pianos, also controls online access to Yamaha piano products, prices, user comments.... there are never prices listed online, instore, anywhere.... piano salesman are horse traders..... look at new piano lines on Yamaha website.... not so much as suggested retail prices.... and!!!! Most piano salesman... and exactly that... salesmen.... don't even play the instrument..... you see the ads? University piano sale... our finest line must go to make room for the newest pianos conservatory students need.... complete bullshit.... used cars.... has there ever not been a great time to buy a mattress? A car, jewelry? Honestly... what does Lincoln's birthday have to do with a circumstance that allows you to save money on a car, mattress. Kitchen cabinets, home appliances.... ??????
Piano sales scenarios kill me... like late night tv ads for exercise equiptment.... they sell a notion .... get two parents in front of a piano salesmen it's like selling a timeshare.... sorry.... I'm going off.... how bout this.... 80% of the top salesman in the piano industry don't play the instrument... nuff said....

pedal cable
by: gaz

where can you buy a replacement PK (I think it's called) cable that connects the pedals to the keyboard? A recent home move with sloppy removals resulted in cable being ripped out! It's a clavinova CVP-98. Many thanks!

fix confirmed
by: Anonymous

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.

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.

Clavinoa Sustain pedal
by: Clavy150 series

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

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

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.
