MY Casio CTK-591 is making a loud 'hummin Noise when I turn it on. Ideas on how to fix?
I assume you mean through its own speakers.
(If you are running through an amp, make sure everything is powered from the same power point)
If the hum is coming from the unit but not through the speakers, you have a more serious problem.
If you are not using the supplied power adapter that could be the problem.
If you are using the mic input, the mic lead could be the problem, or it might be passing close to the power adapter or some other hum source. try a different lead, and make sure the lead is well away from everything.
Some other device might be too close. Try moving things around, or a new location.

How do I factory reset Casio lk 110 keyboard?
Unplug while unit is on. Then press and hold power button for about a minute. Replug back in see if that does trick. If not call company for a hidden code if available.
