The AC adapter’s circular end should be plugged into the power port in the back of the keyboard. If the cable is loose, push the circular end carefully into the power port.
AC Adapter is not Plugged into an Electrical Outlet
If the AC adapter is loose, plug the AC adapter into the electrical outlet. If the AC adapter is not loose, test using another electrical outlet.

If the AC adapter is plugged into both the electrical outlet and the power port, the power port on the keyboard may be damaged.
No Sound Heard Through Headphones
The headphones do not play sound when keys are played
Test headphones using a different device. If no sound is heard through the headphones, replace headphones
Jammed Headphone Jack
Shine a light in the headphone jack to check if there is something lodged. If there is something stuck, remove the object with insulated tweezers.
Headphones are not Plugged into the Audio Port
If the headphones are plugged in but you are still unable to hear sound, the headphone jack may be damaged and need replacing.

Keys are dirty
When the keys are dirty, sounds may not be heard when the keys are played. You will need to clean them thoroughly.
Keys are jammed
Check spaces between keys for any small object preventing upward motion. If there is no visible obstruction, there may be a small object inside of the keyboard causing this jam. See our Key Replacement guide to check under the keys.

Key contacts are dirty. Cleaning will require opening up the keyboard; see the Key Replacement for further instructions.

If the headphones do not work with any other devices, they may need to be replaced.
