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 instrument yourself.
When a message is shown in the display, check the Message List on page 65.
Problem
The power does not turn on.
The power is automatically turned off.
The overall volume is low, or no
sound is heard.
The acoustic piano sound can be
heard even when playing not in the
Acoustic mode.
The balance or volume varies
between the included headphones
and commercially available
headphones.
A rattling sound from the piano body
can be heard when playing in the
Quiet mode/ TransAcoustic mode.
When playing a rapid series of notes
in the Quiet mode/TransAcoustic
mode/Layer mode, a sound louder
than expected (considering playing
strength) occurs.
Rhythm does not start.
Metronome, MIDI Song or Rhythm
goes out of tempo slightly when you
play the keyboard.
No Reverb effect is applied to the
sound even when it is turned on.
The sound lingers excessively.
Noise is heard from the instrument.
The pitch of this instrument is
different from that of other
instruments.
Possible Cause and Solution
The AC adaptor and power cord may not be plugged in correctly. Make sure that the plugs are
securely inserted (page 14).
This is normal and due to the Auto Power Off function. If necessary, disable the Auto Power Off
function (page 16).
The volume is set too low; set it to an appropriate level using the [MASTER VOLUME] control
(pages 19, 21).
The Voice is set to "---." Select a Voice other than "---" (page 22).
Local Control is set to off. Set Local Control to on in Function F7.2 (page 51).
Playing with extreme force may result in acoustic piano sound being emitted. Moderate the
strength of your playing.
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.
This is not a fault. It is the sound of the acoustic piano's keystroke.
This is not a fault. The structure of the TransAcoustic™ Piano or the Silent Piano™ causes
this to occur in some cases.
The Synchro Start function is set to on. Pressing any key starts Rhythm playback. The
Synchro Start function can be turned on/off in Function F6.5 (page 51).
This occurs infrequently when Grand Expression Modeling is set to "Dynamic." If this happens,
set Grand Expression Modeling to "Static" in Function F2.7 (page 46).
The Reverb Depth may be set to minimum. Adjust the Reverb Depth in Function F1.2
(page 45).
(Only on the TA3) When the [TA] lamp is lit (when in the TransAcoustic mode or Layer mode),
the Reverb effect is automatically turned off and no effect is applied.
The Reverb Depth (Function F1.2) or the Damper Resonance (Function F2.2) may be set to an
excessive level. Set these parameters to an appropriate levels (pages 45, 46).
The noise may be due to interference caused by the use of a mobile phone in close proximity
to the instrument. Turn off the mobile phone, or use it further away from the instrument.
The noise may be due to interference caused by the use of a smart device phone in close
proximity to the instrument. When you connect a smart device with the instrument wirelessly,
we recommend that you set that device's "Airplane Mode" to on and then the Wi-Fi/Bluetooth
setting to on on your smart device, in order to avoid noise caused by communication.
The pitch is different depending on the instrument. You can adjust the pitch of this instrument
in Function F3.4 (page 47) to match that of other instruments.
