I've located the source of the annoying plasticky click in some of the black keys on my CA95. Turns out the metal of the keyboard chassis knocks against the plastic of the front rail assembly, when the felt is struck in certain places (see pic and video below). Can anyone suggest a fix?

The screws attaching the plastic rail to the metal chassis are not accessible from the top, so I suspect it's a case of removing the whole keyboard assembly so I can turn it upside down. Has anyone done this or similar before and can offer tips, or can suggest which screws to remove? Might I need to use e.g. glue or felt to stop the parts knocking together?

Thanks smile

Is this "annoying plasticky click" something that developed over time? ... or was it an issue from the start?

Either way is of concern, since I am considering a Kawai MP11 (which I understand has an identical keybed and action) and it will have to be imported (there are none available where I live in Quito, Ecuador) making it very dificult to deal with issues like this even if they are covered under warranty.

One way to stop clicking noises:

. . . Put a thin layer of silicone sealant between the clicking parts.

It works as a very weak adhesive, and a good gap-filler.

You _don't_ want to smear it everywhere, and you _don't_ want it to get onto any electronics.

It's weak enough so that, when you want to take things apart, you can do it.

And it may void the warranty. Kawai James may have some comments . . .

I got it second hand so sorry, I don't know if it was there at manufacture.

Thanks for that! It sounds ideal. I'll order some and give it a go. Just got to work out how to remove the keyboard assembly now.

The warranty is only 1 year labour, 3 year parts, and it's (just) over a year old, so I'd have to pay for labour which is the expensive part for something like this. Kawai also specified that the warranty is non-transferable, so I'd have to claim via the previous owner, which I'm not going to do unless it's something really major. It excludes "attempted repairs", which I'd interpret as meaning anything you break while attempting to fix it is not covered (fair enough); however simply attempting repairs (and not damaging anything upon you wish to subsequently claim) does not affect the warranty.

I have an MP11 and I do not have this issue.

Thank you so much for this post. I have a new ca95 with a similar annoying clicking sound on a few of the keys. I just watched your video and had another listen to my keyboard and I suspect this is same problem I have. I have a technician from Kawai coming to look at in a few weeks so I'll be show him your video if he can't find the problem himself.

Well done on identifying that yourself. I wouldn't have to courage of pulling the instrument apart like that!

Hope you are enjoying your ca95 otherwise... cool
