The answer is repair shop if you don't have tools or experience with soldering. If you do it is simple to take it apart and take the old supply jack out. Take it to an electronic parts supplier so they can match a new one up for you. Make sure that the holes in the circuit board are clean and free of broken pins. Make sure that the traces leading to the holes are intact. Do not use too much heat or they will separate from the board. It might help to take the adapter with you as the jacks and plug have to match in size.

SOURCE: looking for a schematic of the Casio ctk-700 to

The keyboard is LIKELY scanned as a matrix.

You have two problems:

The contacts in the Thomas will have to be totally disconnected rendering use of any of the Thomas organ unlikely.

The second problem is that the keyboard LIKELY has velocity sensing. This means TWO contacts must be used PER note. One contact "makes" first and "breaks" last. This is used for velocity sensing on synths. The Thomas foot pedals likely only have a single contact per pedal, and even if they had two, it is unlikely they sequentially close..

The matrix scanning is accomplished by sensing the connection of two crossing points on a matrix of circuit lines. USUALLY each of 12 wires tie to all of one note across the board. Then two other lines for each octave "strobe" the first make contact and then the second of those strobes the second make contact. There are two of these strobe lines for EACH octave on the board.

Remember that these lines scan at digital logic speeds so wire length and NOISE/STAIC DISCHGARGE PROTECTION is a must.

Hello,

You need a midi to usb interface, otherwise it is quite simple. I personally have an M-Audio interface that plugs into my midi out and plugs into your usb port on your computer. Once done, you can create a profile in Reason for your CTK. Windows 7 will notice the M-Audio device and then you will be able to use midi. You may have to install a specific driver for the particular M-AUdio device (or another midi to usb interface) but that is simple. You do not have to worry about a driver for the keyboard.

In my experience, M-Audio makes about the best midi/usb interface, and they come in all popular configurations. I use a very small 1-to-1 interface, though there are multi port interfaces one can buy. I purchased mine on eBay, though you can find them at Guitar Center if you have one in your City, or alternately Musiciansfriend.com web site. Many online stores sell them though. You amy want to use Amazon or a price comparison web site to find your best deal.

Thank you for using FixYa, and good luck.

SOURCE: no display light on my casio ctk 496 every thing else works

Sorry, but many of the low end keyboards do NOT have backlights. This is especially true of those that have the capability of running off batteries like the CTK-496.

The display in this is a reflectance type that needs ambient lighting to view.

The F key near Middle C broke off my CTK 481. Is this something I can fix myself?


Is it broken to pieces or just came off.
I would open up try glue to pieces together and then swap the repaired key F4 with say the (less used) F6 key.

When wiring around circuit board cracks, one must use adequate sized wires and keep the leads short. Also you MAY have a microscopic crack in yet another conductor that flexes when you play the keyboard and freezes it. Use a high intensity LED light from the topside to "candle" the board and look for cracks. Look for cracking of the board material that may have tiny cracks in the circuit traces.

Keyboard not powering up. Want to change the fuse/s. Don't know where fuse is located.


There probably is NOT a fuse and usual cause is problem with the adapter or the power connectors. Broken solder of the connector in the keyboard is common. Broken cords on the adapter is common as well.

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.

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.

NO power to my Casio CTK 671


OFTEN the power connector in the synth get broken from the circuit board connections.

ALSO verify the adapter is actually putting out the correct voltage or slightly above it..

My Casio CTK-496 Keyboard has three keys (2nd octave F sharp, G, and G sharp that don't play anymore. How do I fix this?


First make sure a keyboard "split" option is not set.

Probably you are going to have to clean the key contacts. They are likely conductive rubber "pills" that are pressed onto a circuit board that has interleaved fingers. Clean both the black pills and the circuit board using ONLY 99% isoprophyl alcohol and Q-Tips.

No power is coming through to my CTK 611, bought a new power unit and this has made no difference


There is a chance that the jack that the power supply plugs into is broken loose or has bad solder joints to the circuit board. I am hoping that you purchased a direct replacement for the power supply.
