SOURCE: Casiotone MT-220 keyboard power cord

I would inspect the unit for corrosion on battery terminals AND the power connector. The connector has a switch when a cord is plugged in, and if this switch doesn't work (they get bent) the unit will not work on batteries.
Best source of power adapters is often your local thrift store.
MATCH the voltage and whether it is AC or DC required AND the polarity if the pin is + or -.
Get one with enough current.

SOURCE: can i change the DC 9V jack on my CTK - 541 music

If you are careful you can. Replace with exact same jack. Your jack has a switch contact that connects the batteries when NOT using the power adapter. You need to find one with exact same pin spacing and layout.

Search for one at Digikey.com an Mouser.com

Here is link to the power jacks, supposedly with the switch contact... compare the photos and spec sheet to match your connector.

Scroll down to "get manual" and click on it to download. IGNORE other download links.
Power input schematic is on page 10, lower right corner. They appear to "or" in the batteries with the adapter if adapter is used. Look for the diodes and also the bifilar power inout filter.

Check where you plug it in, or the info sticker underneath the keyboard, it should tell you whether its AC/DC

I can't get power on my Casio lk-50. ? Help


Hi, There are several common reasons why this and most similar keyboards have this problem.
If you can fit known good batteries, and it works, this confirms the problems will be with the external power supply or connection.
Usually batteries are not available, so.......
Do the obvious.
  1. Is the power supply plugged into a known good mains socket?
  2. is the mains socket switched on?
  3. is the power supply plugged into the keyboard?
  4. is the keyboard switched on?
If the power supply is not the one supplied with the keyboard, then check it is compatible.
(You do not have to buy an expensive replacement power supply, a universal, regulated one, with a selection of connectors will be fine. Supermarkets and the like sell them.)
The manual, or a label on the bottom of the keyboard will tell you the voltage, current consumption, and whether the current is AC or DC.
Invariably the current is DC.
All the Casios I have are 9 Volts, (9V) and very few are more than 300 milli amps (300mA) More milli amps is fine, so the current can be the same or greater.
A TYPICAL power supply is likely to be:-
  • 9 V
  • 300 mA or more
  • DC
BUT DO CHECK
Important
The power supply needs to be REGULATED.

Polarity
This is the way round the connector is wired.
Usually the center is negative (-) and the barrel is positive (+)
This information is molded into the plastic or on a label next to the socket.
On a replacement (universal) power supply, there will be a set of connectors, and when you have selected the correct one, the arrow on the end of the lead should point to the correct polarity symbol on the connector.

Fault finding
The most common fault is the power connector being broken or the solder has been broken.
Slowly moving the connector round, to find it works in some positions, is a sure indication that is the fault.

Repair is quite simple, but there are a lot of screws to take out.
Ideally, drill a hole in the case, where convenient, and fit a metal connector. Now connect to the PCB, in place of the original socket, with flexible wires.
Other wise if it is just solder failure, re solder and glue the socket with epoxy resin (Araldite) or hot glue from a glue gun.
Hope this helps, Chris.

Got a used CTK 720 and it has no power. sugestions


try plugging in without the bateries...Also check your adaptor as well as your ac requirements on your keyboard..It specifically calls for a Casio AD-5 Adaptor.
  • 9V power supply; 850mA
  • Positive sleeve/negative tip This needs to match your adaptor Good Luck

Keyboard AC Adapter


If thje voltage is the same, the current rating is fine at 1000-1400 mA. The accessory will use the amount of current it needs and the fact that there is more "available" does not mean it will use it. The higher current rating will not ruin the equipment. Just make sure the voltage rating is the same. Cheers!

I lost my adapter to my keyboard and I need to find either a substitute or a new way to turn it on without the adapter, HELP!!!.


Some Casio Keyboards use 9V DC (center negative) others 12V DC (center negative).
If check what voltage your Keyboard use. Generic AC adapters are usually center positive. So you have to invert the wire with a new DC plug to make it center negative,
Easiest is to buy a Casio ac adapter made for your keyboard from a Casio retailer.

When I play the keys too fast the whole keyboard shuts off with how can I fix the problem as I recently just began learning the piano I will find it very unfortunate to have to bring it in for repair after...


Is it possible you have the wrong power adapter? Next to the power socket on the back of the keyboard it should say what voltage and how many milliamps it needs (eg: 9v DC 500 mA). You should find a similar rating on your adapter.

If the adapter doesn't quite produce enough mA the keyboard will happily sit doing nothing but shut off when you raise its power requirements by playing a lot of notes.
