Casio ctk574 don't power up
First of all ensure you are using the correct power adaptor and that it is providing the correct voltage and polarity.
If that is all OK try powering up whilst apply light upwards pressure to the connector ( then try with light downward pressure )
If it lights up momentarily or constantly whilst turning on the problem is probably a loose connection which will require soldering.
If nothing then either the connection has been badly damaged or the solder tracks on the pcb have failed.
If you have used the wrong voltage / polarity adaptor you may have damaged circuitry which will probably require specialist repair.
I hope this helps.
Good luck.

I need a Manual that
Go to this site:

Do NOT click on the large "Download Now" as it downloads a PDF viewer you do not need.
Go down to a little red download that is in red. One has to fight with the page a bit and eventually the download of the manual will occur. If you can't make it work, email me and I can send it to you.
The sound IC number is
The integrated circuit that are used are specially programmed for Casio and are not available from electronics stores. They are usually surface mounted and require special tools and skills to replace. You would need to take this to a Casio service center to replace the chip if that is the problem. Frankly, it is UNLIKELY that is the problem unless you can see burn marks on the chip. Keybaord contacts are the usual failure and require cleaning.
I have a 6 month old keyboard and have found that
Thisis hard to troubleshoot... The keyboard insynths are usually scanned as a matrix... If a disconnect diode has failed, then wrong notes can be triggered. There is USUALLY rows of the diodes on the circuit board where the keys hit. There are usually TWO contacts per key in order to sense key velocity. The lkey contacts are usually conductive rubber pills pressed against circuit traces under the keys. One sometimes needs to clean these contacts using 99% isoprophyl alcohol and Q tips.
I would do further testing of ALL combinations of notes played together to see if possibly any others show up as that could point to a particular failure.
(Wk-200) Volume wheel spinning all the way around and not stopping at "min" or "max"
If the volume wheel on your Casio WK-200 keyboard is spinning all the way around and not stopping at the "min" or "max" positions, it is likely that the potentiometer that controls the volume has become faulty or damaged. A potentiometer, or pot for short, is a type of variable resistor that is commonly used to control the volume on electronic devices.
Here are a few troubleshooting steps you can try:
- Power off your keyboard and unplug it from the power source.
- Remove any batteries from the battery compartment.
- Locate the volume potentiometer inside the keyboard. It should be near the volume wheel and will have three pins or legs.
- Check the potentiometer for any visible signs of damage, such as cracks or broken pins.
- Gently wiggle the volume wheel while observing the potentiometer. If it appears to be loose or wobbly, it may need to be replaced.
- If you have experience with electronics and soldering, you may be able to replace the potentiometer yourself. Otherwise, it is recommended that you take your keyboard to a qualified service technician for repair.
If the issue persists after attempting these troubleshooting steps, it is likely that the potentiometer needs to be replaced. In any case, it is best to seek the assistance of a professional technician to avoid causing further damage to your keyboard.

Casio tone bank m120 no power,ic AN8054 has been blown off any substitute for ic is available please let me know
The AN8054 is an integrated circuit used in the Casio Tone Bank M120 keyboard. If it has been blown off, you will need to replace it. An equivalent replacement for the AN8054 is the LM358N, which is a dual operational amplifier that can be used as a substitute. Other equivalent options you can consider include the LM741, LM7808, and LM324. It's always recommended to check the datasheet of the substitute IC to ensure it meets the specifications and requirements of the original IC.

Casio CDP-100 sustain pedal not working
It sounds like you may be experiencing issues with the sustain pedal on your Casio CDP-100 digital piano. The problem may not be with the pedal itself, but with the internal connections or circuitry of the piano.
If you're unable to factory reset the piano and it's not responding to the sustain pedal, it's likely that there is a problem with the main board. This is a complex issue that may require professional repair.
However, before giving up on it, you can try the following steps:
- Check the connections: Make sure that all of the connections between the pedal, the piano, and the power supply are secure and that there is no damage to the cables.
- Check the power supply: Make sure that the power supply is working properly and that the piano is receiving power.
- Try to update the firmware: Check if there is a firmware update available for your piano on the Casio website. Updating the firmware may fix the problem.
- Check the manual: Consult the piano's manual for troubleshooting steps, it may have some information that can help you.
If none of these steps work, it is likely that the problem is with the main board and it will need to be repaired by a professional technician. Unfortunately, this can be an expensive repair. Keep in mind that attempting to repair a digital piano can be dangerous if you're not familiar with the proper procedures and safety precautions.
It's important to keep in mind that the piano was second hand and you were aware of a problem with it and you have been given a lower price as a result. It is also important to note that buying second hand musical instruments may have hidden issues, which is why it's always advisable to inspect it thoroughly before buying it or to buy from a reputable seller who can give you a warranty.

I have a Casio celviano ap-65. It turns on but no sound. Any suggestions?
If your Casio Celviano AP-65 turns on but there is no sound, there could be several possible causes for this issue. Here are a few steps you can try to troubleshoot the problem:
- Check the volume: Make sure that the volume on the piano is turned up and that the volume control on any external speakers or amplifiers is also turned up.
- Check the connections: Make sure that all cables and connections are securely plugged in and that there are no loose or damaged cables.
- Check the power supply: If the piano is plugged into an outlet using an extension cord or surge protector, try plugging it directly into the wall to eliminate any issues with the power supply.
- Check the internal speakers: If the piano has internal speakers, make sure that they are not damaged or malfunctioning.
- Check the settings: Make sure that the piano is set to play through the internal speakers or any connected external speakers or amplifiers.
If these steps do not resolve the problem, it may be necessary to have the piano inspected by a professional. They will be able to diagnose the issue and recommend the appropriate repair.
