Re: My Casio keyboard won't play with the ac adapter but...
Test the continuity of your Adapter (input and output), if it fails your test replace it with the same output voltage requirement's and watch the polarity as well (negative ground mostly or positive ground).

Hi, Assuming you have tested with another adaptor then invariably it is a broken solder joint on the power input connector.
Re soldering will work but eventually the same thing occurs.
Set the connector in epoxy resin (Araldite) or better still mount a new connector in the case and wire with flying leads.
All the best, Chris the Fader.
If thje voltage is the same, the current rating is fine at 1000-1400 mA. The accessory will use the amount of current it needs and the fact that there is more "available" does not mean it will use it. The higher current rating will not ruin the equipment. Just make sure the voltage rating is the same. Cheers!
Casio CDP has Auto Power Off: 30 minutes after last key operation, Auto Power Off can be disabled.
Please read the manual.
If it turns itself off while playing, I would try to buy a new AC Adapter to test. DC cable of AC adapters are often broken internally after much "bending".
If it hasn\'t been dropped or bumped, check the adapter. Work backwards from the keyboard. It doesn\'t take much for the casio adapters to pack a sad. If there\'s an overload in your switchboard, it\'s usually the Casio that packs a sad...everything else is fine, microwave, tv, stereo - just not the casio. Their adapters are garbage and until recently - they\'ve just gotten better
Some Casio Keyboards use 9V DC (center negative) others 12V DC (center negative).
If check what voltage your Keyboard use. Generic AC adapters are usually center positive. So you have to invert the wire with a new DC plug to make it center negative,
Easiest is to buy a Casio ac adapter made for your keyboard from a Casio retailer.
The AC adaptor of my Casio Keyboard has reversed polarity from the Standard Power AV adaptor you get in the market. The center is NEGATIVE. When you try to use a new power supply that is NOT a CASIO original, you may need to reverse the polarity of the plug. Check that.
Is it possible you have the wrong power adapter? Next to the power socket on the back of the keyboard it should say what voltage and how many milliamps it needs (eg: 9v DC 500 mA). You should find a similar rating on your adapter.
If the adapter doesn't quite produce enough mA the keyboard will happily sit doing nothing but shut off when you raise its power requirements by playing a lot of notes.
If you are running on batteries, they are either depleted OR may have corrosion on the contacts in the keyboard which is COMMON problem. If using an adapter, the cords chronically work loose. A last problem is the switching for using battery or adapter can have poor contacts. If you don't have an adapter, get one and get one SPECIFICALLY for the keyboard... I don't know how many I have had to tell they have the wrong adapter and that is why their unit won't work.
