    I Have the same problem with my CTK 601.... It just died on me at the end of a gig and I thought it was the adapter, I purchased a new one and that didn't work. I purchased a set of batteries and that didn't work either. What's going on??? Help, please help.

If you lucky, the power jack may be at fault since it switches from external to internal battery, but most likely the internal supply is what's damaged... IC regulator possibly. A quick voltage check with a volt meter at the power leads on the main board will verify battery or xfmr supply voltage, if voltage is present then look in close proximity for an IC regulator and check for an output.

What do I need to do with my Casio CTK 700 which will make it run on batteries?


If you turn it over, you will see the battery compartment. It runs on 6 AA batteries. Here's a link to the manual. Instructions are on page 13.

Ctk-651 sustain pedal working backwards


Buy sustain pedal made for CASIO or switable model.
Pedal for Yamaha or Roland will work in reverse on a Casio.
If you cannot return for exchange, then open up and solder a different type of micro switch.

I have Casio Ctk-496 and I have MIDI-USB wire. It all works, but Transpose button doesn't transpose and casio chord doesn't work with my computer. And all is still working even if I pull out IN wire from...


Casio Chord is internal to the keyboard and doesn't come out on MIDI. Transpose is similar and while the button may send a MIDI transpose type signal out, the notes will not transpose in your computer...

Make sure you are plugging it into the place for the sustain pedal. If you happen to plug it into the audio out it may kill the sound.

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 CTK-2000 Casio won't turn on. It's plugged in, and I've turned it on.


Does it have a rubber power on button? If ss, it's probably worn oujt. Replace it.

My ctk 2000 casio keeps shutting off


Replace the batteries and get an AC adapter for it! These do NOT work when voltage os too low.
