Yamaha KX88 Open Cover and Removing Keys (see more for WARNING)

WARNING: The KX88 is very delicate inside, there is a good chance you may damage the key switches which are hard to find. I do not suggest that anyone actually perform this activity... and not perform this especially if you are not mechanically skilled. I recommend that you have your KX88 repaired by a factory trained technician.

This video shows how to open the main panel and remove and install keys on a 1980's Yamaha KX88 Master MIDI Keyboard. It opens similarly to a DX7 but it is more involved.

The video is very detailed and step-by-step so it is over 48 minutes long but you can skip to various sections as you desire (as shown below), but I suggest you watch the entire video at least once. You will see why this is best left to a factory trained technician.

The first part of the video is how to open up the KX88, the second part is how to remove and re-install the keys for servicing.
