Troubleshooting - Yamaha Clavinova CVP-105 Owner's Manual

Troubleshooting

Problem
The Clavinova does not turn on.
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 com-
pared to that of the Auto Accompa-
niment or song playback.
The volume of the Auto Accompa-
niment or song playback is low
compared to that of the keyboard.
The overall volume is low, or no
sound is heard.
The damper pedal has no effect, or
the sound continuously sustains
even when the damper pedal is not
pressed.
Style or song playback does not
start.
When the keyboard is played, not
all of the notes sound.
Cause
The Clavinova has not been plugged
in properly.
Electrical current is being applied to
the instrument.
The noise may be due to interference
caused by the use of a mobile phone
in close proximity to the Clavinova.
The brightness may be affected by
the surrounding temperature.
Either the overall keyboard volume
or the independent volume level of
the keyboard part is set too low.
The [ACMP/SONG VOLUME] is
set too low.
The volume level of one or more
accompaniment parts or song tracks
is set too low.
The [MASTER VOLUME] is set too low.
Headphones are connected.
The Local Control function is turned off.
The pedal cord plug is not connected.
The MIDI Sync function is set to EXT.
The Clavinova's total simultaneous
polyphonic capacity (maximum
number of notes) has been exceeded.
Solution
Securely insert the female plug into
the socket on the Clavinova, and the
male plug into a proper AC outlet.
This is normal, and is no cause for
concern.
Turn off the mobile phone, or use it
further away from the Clavinova.
Adjust the contrast of the display
using the [CONTRAST] control.
(See page 11.)
Increase the overall keyboard level
in the main display (page 23), or use
the VOLUME function in the appro-
priate KEYBOARD display (pages
37, 39, or 42) to raise the volume of
the keyboard part in question.
Raise the [ACMP/SONG VOL-
UME] level.
Raise the part or track level(s) in the
appropriate MIXER display (page
77 or 120).
Raise the [MASTER VOLUME] level.
Unplug the headphones.
Turn the Local Control function on.
(See page 201.)
Securely insert the pedal cord plug
into the proper jack. (See pages 48,
54 and 62 in the Reference booklet
for the CVP-105, CVP-700 and
CVP-109/107, respectively.)
Set the MIDI Sync function to INT.
(See page 202.)
Since the configuration of the tone
generation system is such that later
notes have priority, previous notes
may occasionally be cut off. (See
"Specifications" on page 67 of the
Reference Booklet for details about
the simultaneous polyphonic capac-
ity.)
