I have a LK-270, nothing happens when i press any keyboard key.

Power is on, volume is up, nothing is plugged into the phone/output jack.

Is someone can help me out?

Thank you i advance.

Refer to the top of the right hand column of Page EN-60 of the manual to check the status of Local Control.  If Local is OFF, turn it ON.


If Local is already ON in the above step, plug in a set of headphones.  If you hear sound in the headphones, but not from the speakers with no headphones connected, then either the audio switch ib the headphones jack is bad or the keyboard's power amplifier is blown.  Try inserting and removing the headphones plug several times very quickly to see if that resolves the problem.
