If your Casio CTK keyboard (model 3200) has an LCD screen that is not working or is broken in any way, use this guide to replace the screen.

The LCD screen will relay information of what the keyboard is doing to the user visually so you are able to see what key is being pressed, if there is a sound playing, what modifier is active, etc. It sits on the main board and through the main board, it receives the signals that tell it which parts of the screen to light up. This means it is integral to put the screen back correctly and in the same orientation as it was before.

Place your new screen face down into the center panel. Lay the screen exactly as shown in the first image, then let it fall over and land face down into place.
Make sure the screen is right side up. This will ensure that all of the electrical components line up correctly when the main board is re-attached to the center panel.
