Opening Yamaha CLP-240 Digital Piano For Key Repair

After months of dealing with a really annoying stiff/stuck E key on my piano, I finally had enough and decided that I'm gonna risk opening it up my self and swap it with the B key on the very far left. With some careful research online and some guess work (Yamaha still to respond to my service manual and spare keys request email), it wasn't such a difficult job, and I want to share with other people how to do it as well so they don't sit back and suffer from stuck or half stuck (stiff) keys.

Steps:

There is no need to remove the keyboard from its stand. But some open space is necessary to place the Piano top and the sliding cover in safely. I also recommend having an magnetic screw driver to pick up the screws in awkward places.

Clavinova CVP-201 Stuck/Broken Keys Repair
Chinese Technician: Yamaha Clavinova how to replace the keys

1. Unscrew the 3 screws at the back of the piano. They are the screws near the top of the piano that holds the top lid in place. I forgot to take a picture of this, but there are only 3 screws near the top.... or refer to one of the videos which show it if you are worried
2. Now, we can slide the top lid off. Loosen the lid first (img). Do this by grabbing just above the lid on one side, then lift up and slid out a little bit towards the keys. Repeat for the other side. Now it should be easier to slide the lid off, and place it somewhere safe.
3. Remove these plastic covers along the piano cover track on each side( cover on, cover off) . Take the cover off.
4. Take of the 8 screws (lost photos for these) holding the user panel in place. Lift this up out of the way. A good place is to let it rest on the piano cover rails a bit higher up. But the panel does bend when you do this.
5. Take of the big screws and 2 wood screws (img) holding the keyboard bed in place. Now we can move the keyboard back a little bit so they keys can be taken out. To take the keys out. Cut get something thin and rigid, I used a credit card cut in half (img). Find the key you want to take out, look for a triangle near the top of the key, place the cut credit card by this triangle (img) and push down then use your finger to push the key out from the back end (img). Take out the key. You will need to move the keyboard bed back enough to take the keys out, before careful not to push too hard and break one of the circuit boards in the middle that’s in the way of moving the keyboard bed out. Pushing the keyboard bed to this circuit board is just enough for me to take out the keys.
6. Put in new key. Push down and make back end of key high up while you insert the key in by pushing it forward, now let it sit back up and then push the back end in. if it is down properly the key will not wobble or be able to move back or forwards.

   If they metal spring is loose, you have to put it back in by pushing it in then letting it come back out in to these things that hold it in place. (spring in)(spring out)

   Refer to video with the Chinese technician for more help on putting the key back in properly. But remember to let it rest then push back to put it in, no need to keep pushing down on the key when pushing other end.
