SOURCE: My casio keyboards ac adapter does not power up

There is some type of system short. If you read the keyboard instructions it will probably have an "important" note telling you not to unplug the keyboard while in the "on" position. Some how this shorts the connection port. Seems as though Casio could prevent this from happening. I got a refund and went with another brand.

Try this out- check for a blown fuse. If you have never done this before, here is a simpler step by step procedure-
1. If you have the tools and little bit of adventurous spirit, I would suggest you open the keyboard and check for a fuse (a small glass tube with a metal wire running through it).
2. Pull it out and look at it against a light source (like a window) check if the wire if cut (that means the fuse is blown).
3. If it is not blown, put it back, if is blown find a shop that sells it- an electronic spare part shop that stocks stuff for TV, and computer spare will have it). Get a new one and put it in.
4. Try plugging the adapter again.

Best of luck...

My CTK 720 isn't powering on from the adapter anymore but battery power is working. I bought a new adapter but it still isn't powering on. Can this be repaired?


This could be a loose plug inside the unit or it could be a circuit that is bad. If the plug failed it is from physical damage from something like tripping over it or heavy use. That can be repaired by replacing the plug. If it is something like a component in the unit on a board then it becomes a little more involved.

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.

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

I have a Casio CTK 551 Keyboard, when the AC adaptor is connected and power is turned on, the Keyboard lights up for a few seconds then turns off. I noticed no red light lights up when the AC adaptor is...


The adapter has a problem... likely a poor connection of input power that briefly contacts building up some voltage that is then stored in the capacitors in the adapter which then discharge quicklly when you turn on the Casio. The adapters with FIXED blades OFTEN have problems contacting the connections in wall receptacles and extension cords. You may need to bend the blades slightly or use a better receptacle like connector. IF your adapter has a three wire cord from it to the wall receptacle, those SOMETIMES don't seat well...

My casio ctk-710 does not work with the power supply, only batteries and i already try several powers supplys


There is a contact switch in the power connector that must be making for batteries to work... I suspect that either the soldering of the power connector or possibly a broken circuit trace to the power inout connector may be the problem.

My Casio keyboard won't play with the ac adapter but plays when I install batteries. Why doesn't the ac adapter work?


Test the continuity of your Adapter (input and output), if it fails your test replace it with the same output voltage requirement's and watch the polarity as well (negative ground mostly or positive ground).

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