Troubleshooting
If you encounter what appears to be a malfunction, please check the
following points before assuming that your Clavinova is faulty.
Options
BC-8 Bench
A stable, comfortable bench styled to match your Yamaha
Clavinova.
HPE-160 Stereo Headphones
High-performance lightweight dynamic headphones with extra-soft
ear pads.
KC-883 Key Cover for the CVP-59S
A convenient way to keep your keyboard clean and dust-free.
Some items may not be available in
certain areas.
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?
2. No Rhythm, ABC, or Song Playback Sound
Check the ABC/SONG VOLUME control setting. No sound is produced if it is set to the minimum posi-
tion.
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 household 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 Connected 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.
