Troubleshooting

If you encounter what appears to be a malfunction, please check the follow-
ing points before assuming that your YDP-88II is faulty.
1. No Sound When the Power is Turned ON
Is the AC plug properly connected to 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 the Local
Control (page 15) 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 iii).
3. The YDP-88II 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 YDP-88II.
5. Interference Appears On Radio or TV Sets Located Near the YDP-88II
The YDP-88II contains digital circuitry which can generate radio-frequency noise. The solution is to
move the YDP-88II further away from the affected equipment, or vice versa.
6. Distorted Sound When the YDP-88II is Connected to An External Amplifier/Speaker System
If the YDP-88II is connected to a stereo system or instrument amplifier and the sound is distorted,
reduce the setting of the YDP-88II volume control to a level at which the distortion ceases.
