Troubleshooting
If you have problems with the unit, here are a few troubleshooting tips. If you cannot solve the problem easily
yourself, consult your Yamaha piano dealer. DO NOT attempt to repair the piano yourself.
Symptom Cause Remedy
The unit does not turn on. The AC power cable may not be plugged
in correctly.
Insert the AC power cable firmly into the
AC wall outlet (page 10).
The unit turns on but no sound is heard.
The VOLUME knob may be turned to
the far left position.
Adjust the setting to an optimal level
(page 13).
The voice is set to Off. Select the voice (page 14).
The pedal has no effect. The pedal sensor may not be connected
correctly.
Connect the cable firmly to the SENSOR
jacks on the rear of the control unit.
The acoustic piano emits sound when I
am using the Silent Piano™ function to
play.
Playing with extreme force may result in
sound being emitted from the acoustic
piano.
Moderate the strength of your playing.
Since the TA mode is activated, the
sound is heard from the soundboard.
Connect the headphones. Doing so
deactivates the TA mode.
The balance or volume varies when
listening through commercially available
headphones.
Headphone properties differ depending
on their type, so different headphones
may have different balance or volume
characteristics.
Use the same type of headphones for
optimum performance.
I can hear a rattling sound from the
piano body when playing with the Silent
Piano™ function.
This is not a fault. This is the sound of
the acoustic piano’s keystroke.
When I play a rapid series of notes
with the Silent Piano™ function, a loud
sound is emitted that is not part of the
performance.
This is not a fault. The structure of the
Silent Piano™ causes this to occur in
some cases.
Sound is not output properly or evenly. Since the keyboard was held down when
turning on the unit, the unit detects the
keyboard position incorrectly.
Turn off the unit. Remove your hand
from the keyboard, then turn it back on.
No reverb effect is applied to the sound. The reverb depth may be set to 0. Increase the reverb depth to apply an
appropriate amount of reverb (page
16).
The sound lingers excessively. The reverb depth or the Damper
Resonance effect depth may be set to an
excessive level.
Set these parameters to an appropriate
level (pages 16 and 44).
Noise is heard from the headphones or
speakers.
The noise may be due to interference
caused by the use of a mobile phone in
close proximity to the unit.
Turn the mobile phone off, or use it away
from the unit.
The headphones or speakers may not be
connected correctly.
Connect the headphones or speakers to
the corresponding jacks firmly (page
13 or 39).
The pitch of the unit is different to that of
other instruments.
The pitch is different depending on the
instrument.
You can adjust the pitch of this unit to
match that of other instruments (page
40).
