Troubleshooting

If you should experience difficulties with your CP5 or CP50, such as an inability to produce any sound or the output
becoming distorted, work through the following checklists in order to rectify the situation. Alternatively, the Factory Set
function (page 51) can also be used to resolve problems after first creating a complete backup of the stage piano's data
on an external device (page 52). If any specific problem should persist, however, please contact a Yamaha
representative or authorized distributor (see the back of this booklet).
The stage piano produces no sound.
 Ensure that a stereo system, an amplifier and speakers, or headphones have been connected to
your CP5 or CP50.
This stage piano does not come with built-in speakers. In order to hear the sounds that it produces, therefore, you will
need to connect headphones or an external amplifier and speakers (page 15).
 Ensure that the stage piano and the connected audio equipment are turned on.
 Ensure that the master volume on your CP5 or CP50 and on the connected audio equipment are not
set to an excessively low level.
If a foot controller has been connected to the stage piano, try using it to increase the volume.
 Ensure that MIDI volume or expression has not been set excessively low by an external MIDI
controller.
 Ensure that your CP5 or CP50 has been correctly connected to the external audio equipment (such
as an amplifier and speakers).
 Ensure that local control has not been turned off.
If local control is turned off and your CP5 or CP50 is not being used together with a computer or another device
returning MIDI messages, it will not be possible to produce any sound from the internal tone generator by playing the
keyboard.
Press the [UTILITY] button  Jump to Page 5 by pressing the [5] button  Turn Knob 3 to set LocalSw to "on"  Press the [STORE]
button to store this setting (page 48).
 Ensure that no part volumes have been set to an excessively low level.
 Ensure that Part buttons are not turned off.
If a Part button is turned off (i.e., if the lamp to its top-left is not lit), the part in question will not produce any sound. To
remedy this situation, press the Part button and confirm that its lamp lights up.
 Ensure that the output volumes for the Pre-Amplifier blocks and the Power-Amplifier / Compressor
blocks (CP5 only) are not fully turned down.
Each Pre-Amplifier block (voices from E.PIANO category only):
Press and hold the [PRE-AMP] button (for at least one second)  Jump to Page 4 by pressing the [4] button  Turn Knob 2 to set the
Volume parameter to an appropriate level. (See the Reference Manual pdf document for more details.)
Each Power-Amplifier / Compressor block (CP5 only)
Press and hold the [PWR-AMP] button (for at least one second)  Set the volume to an appropriate level. (See the Reference
Manual pdf document for more details.)
