Troubleshooting
If you encounter what appears to be a malfunction, please check the following points before assuming
that your Clavinova is faulty.
1. No Sound When the Power is Turned ON
Is the AC plug properly connected to the Clavinova
and an AC wall outlet? Check the AC connection
carefully. Is the MASTER VOLUME control turned
up to a reasonable listening level?
Also make sure that a pair of headphones is not
plugged into the PHONES jack, and that the Local
Control (page 29) is ON.
2. The Damper Pedal Doesn’t Work
If the damper pedal doesn’t work, or notes are
sustained even when the pedal is not pressed, make
sure that the pedal cord is properly plugged into the
main unit (page 46).
3. The Clavinova Reproduces Radio or TV Sound
This can occur if there is a high-power transmitter
in your vicinity. Contact your Yamaha dealer.
4. Intermittent Static Noise
This is usually due to turning ON or OFF a house-
hold appliance or other electronic equipment which is
fed by the same AC mains line as your Clavinova.
5. Interference Appears On Radio or TV Sets
Located Near the Clavinova
The Clavinova contains digital circuitry which can
generate radio-frequency noise. The solution is to
move the Clavinova further away from the affected
equipment, or vice versa.
6. Distorted Sound When the Clavinova is Con-
nected to An External Amplifier/Speaker
System
If the Clavinova is connected to a stereo system or
instrument amplifier and the sound is distorted, reduce
the setting of the Clavinova volume control to a level
at which the distortion ceases.
● If “ Scn ” appears on the display an internal malfunction has occurred. In this case, contact your Yamaha
dealer.
