Troubleshooting Problem • The Clavinova does not turn on; there is no power. • A click or pop is heard when the power is turned on or off. • Noise is heard from the Clavinova's speakers. • The display is too bright or too dark to read. • The keyboard volume is low compared to that of the Auto Accompaniment or song playback. • The volume of the Auto Accompaniment or song playback is low compared to that of the keyboard. • The overall volume is low, or no sound is heard. • The damper, sostenuto and soft functions do not work for the relevant pedals. • The damper pedal has no effect, or the sound continuously sustains even when the damper pedal is not pressed. • Not all simultaneously-played notes sound. • Accompaniment style or Song playback does not start. • Only the rhythm channel plays. • The accompaniment style does not start, even when Synchro Start is in standby condition and a key is pressed. • The desired chord is not recognized or output by the auto accompaniment. Possible Cause and Solution Make sure that the Clavinova has been plugged in properly. Securely insert the female plug into the AC socket on the Clavinova, and the male plug into a proper AC outlet (page 17). This is normal when electrical current is applied to the instrument. Using a mobile phone in close proximity to the Clavinova may produce interference. To prevent this, turn off the mobile phone, or use it further away from the Clavinova. The brightness of the display may be affected by the surrounding temperature; try adjusting the contrast (page 17). The overall keyboard volume or the independent volume level of the keyboard part may be set too low. Raise the MAIN/LAYER/LEFT volume voices or lower the STYLE/SONG volume in the BALANCE display (page 62). The volume level of one or more accompaniment parts or song channels is set too low. Raise the part or channel level(s) in the appropriate MIXER display (page 120). • The Master Volume is set too low; set it to an appropriate level with the [MASTER VOLUME] dial. • The volume of the individual parts may be set too low. Raise the volume of MAIN, LAYER, LEFT, STYLE, and SONG in the BALANCE display (page 62). • Make sure the desired channel is set to ON (page 62, 77). • Headphones are connected, disabling the speaker output. (This happens when the speaker setting is set to "HEADPHONE SW"; page 141.) Unplug the headphones. • Make sure the speaker setting is set to ON (page 141). • Make sure the Local Control function is set to ON (page 137). Each pedal has been assigned to a different function. Make sure that each pedal is properly assigned to SUSTAIN, SOSTENUTO, and SOFT (page 131). The pedal cable/plug may not be properly connected. Make sure to securely insert the pedal plug into the proper jack (page 153 - 156). You may be exceeding the maximum polyphony of the Clavinova. When this happens, the earliest played notes will stop sounding, letting the latest played notes sound. See page 159 for information on the maximum polyphony. • MIDI Clock may be set to "EXTERNAL." Make sure this is set to "INTERNAL" (page 138). • Make sure to press the appropriate [START/STOP] button. To play an accompaniment style, press the STYLE [START/STOP] button (page 62); to playback a song, press the SONG [START/STOP] button (page 75). • "New Song" (a blank song) has been selected. Make sure to select an appropriate song in the SONG display (page 75). • The song has been stopped at the end of the song data. Return to the beginning of the song by pressing the [TOP] button (page 77). Make sure the Auto Accompaniment function is turned on; press the [ACMP] button. You may be trying to start accompaniment by playing a key in the right hand range of the keyboard. Make sure to play a key in the left-hand (accompaniment) range of the keyboard. • You may not be playing the correct keys to indicate the chord. Refer to "Chord Types Recognized in the Fingered Mode" (page 64). • You may be playing the keys according to a different fingering mode, and not the one currently selected. Check the accompaniment mode, and play the keys according to the selected mode (page 63). CVP-205/203 157

Troubleshooting
Problem
Possible Cause and Solution
•
The Clavinova does not turn on; there is no
power.
Make sure that the Clavinova has been plugged in properly. Securely insert the
female plug into the AC socket on the Clavinova, and the male plug into a proper
AC outlet (page 17).
•
A click or pop is heard when the power is
turned on or off.
This is normal when electrical current is applied to the instrument.

The brightness of the display may be affected by the surrounding temperature;
try adjusting the contrast (page 17).
