Casio LK-100 Keyboard - Page 3 Questions & Answers
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 CDP - 120 turns itself off
Casio CDP has Auto Power Off: 30 minutes after last key operation, Auto Power Off can be disabled.
Please read the manual.
If it turns itself off while playing, I would try to buy a new AC Adapter to test. DC cable of AC adapters are often broken internally after much "bending".
