Pss680 keyboard ,we turn the button on and no power.we have tried it with batteries and the adaptor and still no power,wondering if you are able to offer some advice.

Hi
In terms of no electrical power it could be either a faulty power adaptor, broken socket. However the feedback with batteries could indicate a more serious fault. If the batteries are know to be good try a reset. Hold down the highest sounding key while turning the keyboard on. Release once you have lights or a display on screen. Has the noise stopped? If so then try electrical connection again, if still no power ensure you are using the correct power adaptor and see if it works if you wobble the connector - they break away causing an intermittent fault. Report back and maybe I can offer more advice depending on how you progress with the above.

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

The AC adaptor of my Casio Keyboard has reversed polarity from the Standard Power AV adaptor you get in the market. The center is NEGATIVE. When you try to use a new power supply that is NOT a CASIO original, you may need to reverse the polarity of the plug. Check that.

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...

YES.

It might be that the contacts for the headphone jack is very dirty. Try using a cotton swab with a wd-40 on it to clean the inside contacts on the jack.
