ALWAYS start with the "easy" things 1st. Is the AC outlet on the wall working properly? Is the "wall-wart" power supply working correctly? If no defect is found, check the DC power jack located on the rear of the keyboard. Does it seem to be loose or does moving the power supply jack up/down cause any change? New wall-wart power supplies can be purchased from Radio Shack and usually at a lower price than the original factory replacements.
The best place to get most products such as these are usually online. You can search Ebay.com or try the official casio website. But the unit you are looking for will be easy to get online. Try searching google phillipines or yahoo phillipines. Incase you need more assistance let me know. Hope this solution has been helpful?
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.
kindly leave the battery for long duration in charging position let the red light blink and then see after like 16 hours or 24 hours if it works and charge otherwise change the battery with the same specs , and next time when u leave battery for long duration likea month or weeks charge it to full or half so it can hold some power to re charge again , ur battery is in Coma state nearly dead so it might come back or not
u mean no power at all?
If yes, try to reset it. (NOTE: This method will RESET all of ur programmed data!)
1. Off power
2. Take out the AA size backup battery
3. On Power
4. The machine should show "0000000000"
5. Fix the AA battery in
6. Program the Date & Time
7. Ok
