There are 5 screws in the back, 3 long, and 2 short screws in the middle, and 2 screws on the front tips.
Be careful of how you lift the upper cover (the silver part), as there are fragile connections inside.
IN THE KEYBOARD:
the keys are attached in groups (octave-wise) unscrew them and you deal with them individually.
Be sure to clean the area where the pressure switches meet the electronic circuit, even a little amount of dust can cause distortion in the sound.
Most of the physical problems occur only in the keys, so now you can fix them easily on your own!
Label all the screws in advance so you where to put them back.
If any queries, feel free to post!:)
