Repair and disassembly guides for Casio electronic keyboards.
Why is there a squeeking sound in addition to the normal sound when keys are pressed, speaker problem?
What is the model number of the keyboard?
If the keyboard has an earphones socket try plugging in a set of earphones and check if the problem is still there when using them.
Doers it happen on all "notes" just a few or just one?
