Einleitung

Pitch bends can stop working. If you cannot hear the difference in sound when you adjust the pitch blend, it may be time to replace it. This guide will show you how to replace the pitch bend on the side panel of your device.

JIS #1

Schritt 1

Flip the keyboard upside down, with the keys on a flat surface.
Remove the three black 14mm Japanese Industrial Standard (J) head screws using a J1 screwdriver on the top half of the outermost side panel.

We have this model and the pitch is bending intermittently on it’s own. Do you think disconnecting the bending ‘wheel’ would stop this or is it more likely to be a faulty chip?

Thank you for any help!

Schritt 2

Use two hands to grab the side panel from both sides.
Pull the panel apart from the device one side at a time.
There will be popping sounds when you remove this panel.
One side panel will not have an orange & white cable connected to it.

Schritt 3

Remove the three silver 10mm screws with a J1 screwdriver on the bottom half of the innermost side panel of the device.
One side panel will not have an orange & white cable running through.

Schritt 4

Remove the innermost side panel by pinching the top and bottom of the panel and pulling the panel off with both hands.
There will be popping sounds when you remove this panel.
Repeat steps one through four to remove the other side panel of the keyboard.

In my model CDP230, upon removing the inner most side panel, 2 screw brackets will come loose each side. It will fall somewhere behind - you will need these when closing once again the panels. It has its own alcove but because the keyboard is now on its back (flipped), it will naturally fall out. What I did was to place the keyboard in its natural upright position when closing the inner and outer panel. And placing this screw bracket at closing the inner bracket.

Schritt 5

Remove the two black 30 mm J head screws with a J1 screwdriver to remove the long black bar.
Remove the four silver 8mm x 2mm J head screws with a J1 screwdriver and the two brackets from the back panel.
There will be two screws per bracket.

Schritt 6

Remove the eight silver 10mm x 1.5mm J head screws with a J1 screwdriver and the square tabs from the back panel.
Remove the eight silver 10mm J head screws with a J1 screwdriver underneath the square tabs.

Schritt 7

Remove the 36 silver 10mm J head screws with a J1 screwdriver from the back panel.

Schritt 8

Place a hand on the front panel and speakers and carefully flip the keyboard over with the keys facing up.
Having a extra pair of hands will be useful.
Grab the center of the front panel with two hands and lift to remove panel.
Grab the speakers from the sides and lift to remove. Once you have done this for the first speaker, repeat with the second speaker.

It seems impossible to take the front panel out unless I break it. How did you do it?

I’m having the same issue. Did you ever figure out how to remove the front panel? Thanks

My experience 1st time doing it was terrible because of the double sided adhesive tape applied by the factory. So with gentle traction and plenty of patience it did finally give way. The second time around it was much easier.
