Problem
Possible Cause and Solution
The YDP-123 does not turn on.
The YDP-123 has not been plugged in properly. Securely insert the female plug into
the socket on the YDP-123, and the male plug into a proper AC outlet (page 11).
A click or pop is heard when the power is
turned on or off.
This is normal when electrical current is being applied to the instrument.
Noise from the speakers or headphones is
audible.
The noise may be due to interference caused by the use of a mobile phone in close
proximity to the YDP-123. Turn off the mobile phone, or move it further away from the
YDP-123.
The overall volume is low, or no sound is
heard.
• The Master Volume is set too low. Set it to an appropriate level using the [MASTER
VOLUME] control.
• Make sure a pair of headphones is not connected to the headphones jack.
• Make sure that Local Control (page 26) is ON.
The damper pedal has no effect, or the sound
continuously sustains even when the damper
pedal is not pressed.
The pedal cord may not be properly connected. Make sure to securely insert the pedal
cord into the [PEDAL] jack (page 30).
