Take it in for service. Sounds like it needs a new switch or control board.

How do I reset a Casio CTK 4400 keyboard?

Turning it on and off and on again initializes the keyboard settings. Page EN10 in the manual make that clear. The manual also has a troubleshooting section in the back. https://support.casio.com/en/manual/manualfile.php?cid=008001061

My Casio Ctk-3200 keyboard can't get switched on with the power line, but it works with batteries.

You probably have shorted out the power supply. Test it with an ohm meter for proper operation. If it's not working, replace it. If it is working, then the power supply board in the instrument is shorted and you'll need to take it in for repair.

My Casio ctk 811ex wont power up anyone more.Is there an internal battery that needs replacing ? What could be causing the problem ? 2 weeks ago it was working fine

ALWAYS start with the "easy" things 1st. Is the AC outlet on the wall working properly? Is the "wall-wart" power supply working correctly? If no defect is found, check the DC power jack located on the rear of the keyboard. Does it seem to be loose or does moving the power supply jack up/down cause any change? New wall-wart power supplies can be purchased from Radio Shack and usually at a lower price than the original factory replacements.

try plugging in without the bateries...Also check your adaptor as well as your ac requirements on your keyboard..It specifically calls for a Casio AD-5 Adaptor.
  • 9V power supply; 850mA
  • Positive sleeve/negative tip This needs to match your adaptor Good Luck

I have casio CTK 496. I can turn it on only over battery power. When I try to turn it on over power cord it does not doing anything. can you tell me what is possible wrong. And I can I disassemble cover?...

The jack for the power supply is soldered to the circuit board. It is likely you have bad solder joints. Keep careful track of which screws go where and you should be able to take it apart enough to get to the solder joints. The screw holes are on the bottom.

My casio ctk-710 does not work with the power supply, only batteries and i already try several powers supplys

There is a contact switch in the power connector that must be making for batteries to work... I suspect that either the soldering of the power connector or possibly a broken circuit trace to the power inout connector may be the problem.

I have this casio CTK-491 Electronic Keyboard that is not working on its power suppie. It did work at first then i had to wiggle the plug to get it to work and now it stop working is the a part or easy fis...

This could be ay number of things, but assuming that the power supply is fine (the cord isn't broken on either end or down the length of the cord) then it'll probably be a loose connection in the keyboard.
With CTK models if you unscrew the back (not the metal plate) you can open it up, have a look where the connections are going from the power supply socket and re-solder to the board etc if nessesary. Also if you have some strong glue then glueing the adapter in place on the PCB as well as the headphone socket would be a good idea as these connections are used quite a lot and the parts do come loose.

Casio CTK-651 keyboard wont switch on

An internal fuse is UNLIKELY.

More likely is either a bad connection/connector at power input or a bad or intermittent power switch.
