If batteries or power adapter does not power up the keyboard...possibilities are...if it has a fuse inside or fusible link check it.replace if blown.Another possibility is power component has a short. maybe from constant movement of power plug into keyboard.sometimes just by inserting the plug and wiggling it can solve the issue..having this fixed by a technician can cost a lot of money.but,if your keyboard`s value is less than the cost of fixing it,might as well replace your instrument.

It sounds like the actual button switches are going bad. Those would normally be replaceable id you can find an electronic tech that is competent. The internaal backup battery may be bad causing loss of the songs. One would have to look at the switches and find a substitute supplier. These switches are often very tiny about the size of a pencil eraser and are actuated by the larger buttons on the panels. You can probably find them at Digikey.com or Mouser.com. They typically cost about 30 cents each... Disassembly and desoldering and soldering qill be required. The internal parts of the switches wear out.

Key contacts are dirty. The contacts are conductive rubber pills that get pressed against circuit traces on a board undder the keys. Clean the rubber pills AND the circuit traces with ONLY 99% isoprophyl alcohol and Q Tips. Be careful of the cables when opening the unit. There is also a slight chance that a cable has come partway loose internally. If you are uncomfortable with opening the unit and keeping track of all the screws, better take it to a repair shop.

The adapter required is a 12 volt 1.5 amp (1500ma or 18 watts). Check the polarity carefully as to whether the pin or the shell is positive... Many Casio have the shell as positive but do NOT gamble, check for the markings near the connector.

If you are not using the original pedal it means that your pedal is wired backwards. You can try disassembling the pedal or the plug on the cord and reversing the wiring of the connections to see if that helps. Example if the shield of the cable is wired to the shaft of the plug, try disconnecting the wiring to the shaft and tip and wire the shield to tip etc.

The quickest thing to do is to match the connector with catalog illustrations at either Digikey.com or Mouser.com.

Search first for 1/4 inch, then filter selection with STEREO and PCB or circuit board mounted.
There is likely switches involved to turn off the speakers.

Finding a Casio parts list for the unit could be a major undertaking AND the part number would likely be a house number that you can only use directely from Casio.

Here is a link to some of the candidate ones:


For those without an image, click on the part number and go to the PDF spec sheet for image.

This is likely a problem in the scanning matrix of the keys and switches. Other than opening the unit and looking for contamination like a metal shard or a loose cable, it is unlikley you will be ablle to repair the unit yourself. There could easily be a metal part shorting something that is causing the problem, but it could also be a bad IC someplace in the circuitry or even a cracked circuit board.

I had the same problem. You might try the keyboard on good fresh high quality batteries. If this solves the problem, buy another ac power adapter. Good luck!!

Hello - I am too a personal owner of a CASIO CTK keyboard, a little older than yours (model CTK-601) a great keyboard BTW, and I have connected it to my computer successfuly.

There are 2 ways of connecting the keyboard to your PC......Using the MIDI outputs and a special MIDI to gameport adapter - if you have a very old system and have a joystick port (D-sub shape) on your soundcard or PC, then you use that cable. Of course this is legacy and stopped existing in newer computers, now USB is used.

Only the professional line of soundcards have direct MIDI inputs. For most of us, with consumer soundcards and PCs, there are no MIDI inputs.

The good news is that newer keyboards support USB MIDI and features direct USB connection - so all you have to do is install the drivers that are provided with your keyboard, usually a CD, and follow the instruction to install the USB drivers for your casio keyboard, BEFORE you plug in the cable (very important!) once installed you reboot and connect your keyboard using a USB cable

Now if your keyboard is older and has MIDI outputs, like mine for example, you will need to purchase a MIDI to USB adapter, those have MIDI cables in one end that plug to your keyboard and the other end a USB connector....... I don't know about the rules if I am allowed to post websites, but the product i'm using is the Uno from M-Audio - in google do this search:


(exactly as shown above with quotes, and uno outside quotes)

Your CTK-810 may alreayd have a USB connector on it, as it is a newer generation keyboard - I am pretty sure it does - what you will have to do as stated above is located your bundled CD-ROM and install the USB drivers - you will need to purchase a USB cable (seperately).

Have you tried signing on to your computer as the administrator? I looked at the support pages at Casio and saw how confusing they are. Look at page: http://support.casio.com/information.php?rgn=5&cid=008&pid=114 and page: http://support.casio.com/information.php?rgn=5&cid=009&pid=115. Pay attention to the red lettering. The computer might be considered as the midi out device and the keyboard as the midi in device or the other way around, I'm not sure. Pretend its a telephone conversation with one person talking and the other person replying. I don't know if this helps but you can also try tech support at Sweetwater Sound (800)222-4700.

If no fuse holder is evident on the rear panel, check for an open fuse inside.
