CLP-130 crackling sound

Unread post by Pete Kirby »

My CLP-130 Clavinova has developed an intermittent crackling sound. I've opened it up and cleaned it up a bit but it still persists. I think the sound is coming from one of the circuit boards (see photo). Just wondering if there's a fix for this or whether time is up on this keyboard. Thanks in advance for your help. Pete :)

Hello Pete,

I am working on the same issue, on a very similar board, just more populated. I should have an answer by Tuesday, if replacing all the Capacitors fixes the issue. If so, I have also shared my mouser shopping cart so you can order the same parts.

Hi Pete, welcome the forums :)

It is likely failing or failed capacitors.

viriiguy has a bit of a project on the go at the moment to replace the caps in his CVP 900. Might be very useful to follow his progress (Y)

Thanks for the messages, guys. Strangely enough the crackling seems to have abated for the moment. Maybe it just needed playing more! I'll keep an eye on it though - and also your progress with the capacitors in case the problem resurfaces.

Glad to hear it has cleared up for now. However, knowing what I know about circuits, it will be back. The Capacitors are drying up, which is usually what causes these types of issues. They have a rated life span of about 15 years, so anywhere from 10-20 years is the failure point of a Cap.

Hello, i have a similar problem. All keys except the highest register make oscilating noise. Only vibes(vibraphone) works completely fine. Do you have any suggestions? Thanks in advance!
