Can’t see anything wrong when taken the lid off and checking the key hitting the pad . Sounds like there is no padding but strips looks intact

Is there anything I should remove from the key ?

Typically this problem stats from debris accumulation in the key pad.

In order to fix this issue, you have to open the keyboard and clean out the contact strip of the loud key. Remove any kind of debris accumulation into the key. For cleaning, you should use ethanol, while also alcohol can be used. You can use the following video as a reference into how to clean the key:

Let me know if this procedure has worked otherwise I will provide instructions to replace the key.

Let me know if other follow up question arises so I can answer it! :)

Thanks for your answer , I have started opening the clavinova so still in the process , will update you tomorrow

OK! What is the result?

Great result , got some debris out and a good hoovering and clean needed of the green strip under the mother board . Now all keys working well . Used the utube video , interestingly I had looked at that beforehand but wasn’t sure but after your recommendation I did it . I have never done anything similar and is not very electrical inclined , so very happy with the result . Thanks for your help

You are welcome!
