Check to see if your cord is plugged into a working powered outlet. Also check your batteries to see if they're dead or in the incorrect orientation. If you're not using batteries, you may have a damaged power cord. Check for any tears in the cord.
If you discover a tear, electrical tape will temporarily fix this problem. Electrical Tape can be found at any hardware store. Once you have it, wrap it around the tear on the cord. If the keyboard is plugged in to a working outlet, the batteries are fresh, or your cord is not damaged and the problem persists, then you have a bad internal connection. Meaning there is a damaged electrical wire within the board.
Refer to one of our CTK installation guides to open the device. Check if the keyboard is plugged in to a working outlet. If it isn't plugged in check the batteries on the under the back panel. One or both of your speakers could be damaged. An electrical wire attached to the speaker may also be damaged. Casio CTK Speaker Replacement installation guide will help you replace any damaged wire connection. Underneath each key, within the keyboard, is a blue rubber bud.
It looks like the rubber piece at the tip small headphones. This blue rubber bud is responsible for communicating with the computer chips within the board. If it is missing than there will be no sound. Your LCD screen maybe damaged. First, see if there is anything obstructing the key's movement externally. If not this is most likely an internal problem.
There could be a build up of dirt or debris within the keyboard near the keys. We have a casio WK keyboard at school and the pin in the 12v power jack has broken do you have any ideas where i can get one. Have tried marlins but they don't sell them. I have a CTK and my piano isn't working. I have tried to replace the batteries however this had no impact.
The screen wont turn and and no sound comes out, nothing seems to work at all. What can I do? Thank you. Is there any way to fix this? Fix Your Stuff. Edit Options History.

Bad power supply.The Casio SK-1 is a small sampling keyboard made by Casio in It also features a small number of four-note polyphonic preset analog and digital instrument voices, and a simple additive voice. All voices may be shaped by 13 preset envelopesportamentoand vibrato.
It also includes a rudimentary sequence recorder, preset rhythms and chord accompaniment. The SK-1 includes one pre-arranged piece of music, the Toy Symphonywhich is played when the "Demo" button is pressed. The SK-1 has been used by a few major recording artists for its simplicity and lo-fi sound. It became very popular in the late s among the circuit bending crowd after the first guide to bending it was published by Reed Ghazala in Experimental Musical Instruments magazine, though the SK-1 was being modified as early as when Keyboard Magazine published an article on adding MIDI support.
The synthesizer was one of the first pieces of equipment that Autechre had when they began recording music.
It was used by notable jungle artist DJ Hype for his seminal productions,  and rapper and producer Large Professor used it in his early years of beat-making. It is also featured on the cover of the Soccer Mommy album "Collection". From Wikipedia, the free encyclopedia. Small sampling keyboard.

I have been working with PC's for as long as I can remember, but this is a first for me What type of connection does it have i. PS2, USB, etc If by chance you had it open, and you plugged in the connector to the internal circuit board which you would have to force the connectors together since they are most likely a mating pair with polarized keys or detents to prevent them from being connected backwards Post pictures of the circuit board in question This would help in determining if there could be something else to check.
I would be VERY interested to see how this was managed also. Hi BMorse thanks for the response. Full newbie here ha. See pictures. By reversing the connector you may have very well fried the controller, which unfortunately is under that "black" blob SgtWookie Joined Jul 17, 22, Yep, it's a "binner" - for those of you unfamiliar with UK slang, that means it's ready for the dust bin, also known as a trash can. You say you have 2 to repair? Have you blown both of them in the same way?
Too bad that you insisted Jazz Bass Special Joined Apr 9, I wonder how much HP "saved" by using that connector. Non-polarized connectors are rare now a days.

Electronics Forums. Casio Keyboard: no power Reply to Thread. Search Forums Recent Posts. Scroll to continue with content. Oct 8, 1. The power 'on' switch on my Casio Keyboard no longer turns it on.
How do I find out if it is a faulty switch? It is a DPDT slide switch with 6 soldered terminals into the circuit board. There is also a red LED which should light up when the power is on. If the LED had failed, would this prevent the power being turned on? If the switch terminals are numbered 1,2 and 3 on the left, and 4,5 and 6 on the right, 2 and 5 being middle terminalsI can get continuity as follows: Switch 'ON' 2 to 3 and 5 and 6 3 to left terminal of LED 2 to left terminal of LED Switch 'OFF' 1 to 2 and 4 to 5 3 to left terminal of LED Any help would be much appreciated.Repair Casio CDP Piano - No power.

How to Troubleshoot a Casio Piano Keyboard
What power do you use, battery's or a mains adapter, or just a power mains lead?. This is where to start, is power going beyond the switch, or is this fine. Use a multi meter on AC or DC volts to determine how far the power is going.
Select a range on the meter above the working voltage of what you plan on testing, if its mains voltage bare this in mind, its all to easy to forget and get a high voltage shock, so if mains voltage take care. But before you call the switch a write off, test how far power is going, a common fault on key boards is the power jack socket solder joints, that's why i asked about the key boards power requirements, if its a mains voltage supply straight to the key board it could be a primary fuse.
Switches a fairly hardy components, and take a lot of on and off's, although they do fail some times. But i would start on the power route first.
Last edited: Oct 8, Oct 8, 3. Casio Keyboard Thank you, Dave, for your response. I have only been using a mains adapter on 9 volts. The power is certainly getting to the soldered terminals of the jack socket on the PCB, but I don't know how to trace how far the power is travelling along the PCB.
Should I expect 9 volts going into the switch regardless of the switch position, and 9 volts coming out when the switch is 'on'? Oct 8, 4.
Ok yes 9 volts to the switch, when on is there power the circuit side of the switch, if no then your original suspicion could be correct, the switch. PS, beyond that we would need some pictures. Oct 8, 5. Connecting pins 2 and 5 to the negative terminal of the mains adapter give readings of 0. With the switch 'on', pin 3 to negative terminal gives 0.

You can play piano pieces, record performances and add tones to many of these Casio piano keyboards. Musical Instrument Digital Interface MIDI is a major component of these keyboards, making them very complex electronic musical instruments.
Fortunately, there are some tips to troubleshoot your Casio piano keyboard if it starts to have problems. Check the position of the batteries or how the AC adaptor is seated, if you are using one. The adaptor should be snugly plugged in to both the keyboard and the wall outlet. Move the "Mode" switch from "Chord" or "Fingered" to "Normal Mode," as normal play on the keyboard is not allowed in "Chord" or "Fingered" modes.
Reset the keyboard and take it out of "Record" or "Record Standby," as the "Split" and "Layer" functions cannot be applied in these modes. Test the keyboard batteries to prevent distorted sounds, loss of power or low volume function when playing or recording from a connected MIDI instrument or computer. Make sure to turn off the "MIDI Thru" function on the computer to prevent unnatural or incorrect sounds when the keyboard is connected to the computer and you are playing on the keyboard.

Kennedy University and a bachelor's degree from Cornell University in counseling. Share It. Move the main volume slide up on the keyboard so that sound will be played through the speakers. Return control of the sound to the keyboard by enabling "Local Control.
Move the "Auto Accompaniment" volume up from to the desired volume setting.
Turn on channels "6" through "10" on the "Auto Accompaniment. Turn up the volume to the desired setting on these channels on the "Auto Accompaniment. Check the volumes on these melody channels and turn up any that are set too low.
