No matter the instrument is turned on or off, a popping
sound will be temporarily produced.
There is no sound even when the keyboard is played or
when a song or style is being played.
This is normal and indicates that the instrument
is receiving electrical power.
Check if any cable or headphone is connected to
the PHONES jack on the rear panel. When a set
of headphonesis plugged into this jack, no sound
is output.
