Hi - there is no
There aapparently is no reset proceedure other than cycling the power. You don't tell us if you are on battery or an adapter. Use of incorrect adapter or failing batteries could cause this. The lights run LONG after the batteries will no longer generate sounds. If on an adapter, try using fresh batteries to see if it might work on battery... if it does, then your adpater or the connector may be bad.

I have a Casio CTK-711ex keyboard .How easy is it to replace the ac input?ta John.
If you have the part, you need a soldering iron, solder wick and solder. Apply heat with the iron to the lugs on the input that protrude through the circuit board, and apply solder wick to desolder the bad part - do this for all the contacts. Remove the bad connector, place the new one and heat the lugs one at a time, once the iron has been on the lug for several seconds, apply the solder to the lug and hold for a second or two. When the solder melts and flows remove the iron and the solder. Allow it to cool - repeat for all the lugs. A good solder joint is shiny. A bad one is dull, and that is called a cold solder joint. If you get a bad one, just heat it back up and wick the solder away and start over.

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.
post any responses back and we might be able to help further.
