Hi @asarnthutube, Yes, the loud note issue can be fixed. But first, check the settings of your piano to ensure that this issue is not a settings issue. Then, if you are sure that it is hardware issue, I believe the problem you are facing is from a faulty group of rubber buttons. In your piano there should be three levels rubber buttons under each piano note key. And these rubber buttons usully come in groups of 11 or 12 notes. So as per your description, mostly one of these groups is faulty. I believe this can be fixed by replacing the group of the faulty buttons. Check this link or find a local store that can send you this: artaudioparts.eu/products/rubber-contact-12keys-for-yamaha-cvp-305-307-309-403-405-407-409-503-505-605-609 By the way, I have also replaced them jn my piano, but unfortunately did not record the process. And I bought them from the same shop I mentioned in the description. Good luck!

@@sam.ammatouri Thank you for your informative post. Unfortunately, the rubber contact key from the link is out of stock. Do you know if another store might have it? By the way, can the faulty rubber buttons be reconditioned and reuse?

@@sam.ammatouri Just found one from eBay. Thank you.

Well, I am not sure about the CVP-307, but I believe it is very similar to my piano 305. In my case it took a bit longer time because I was filming and working all alone. However, I can estimate that a person with skilled hands and with some support from another person, the process to reach into taking off the whole keyboard should take 1 to 2 hours, depending on the skills of the technician.

And for someone with some support from another person, both doing it for the first time on such an instrument?

@@inspirame7979 Well, for first timers doing such jobs, I would say no less than 2.5 to 3 hours, given the fact that you need to separate the screws in labelled containers, and to track back the steps, to ensure no mistakes are made.. My advice is to make yourself free for a day for the whole process.

There’s another video on KZfaq taking the back off the 307! I have one too and some of my central keys are a bit heavy to press. I think that dropping pad is my issue too.

Thanks

Thanks :)
