Troubleshooting
• Sound may not be heard clearly when certain sources play in DOLBY PRO LOGIC II surround mode.
Signals or sound effects to create realistic scenes are sometimes included on the DVDs and BS digital broad-
casts that support 5.1ch. However, they are not included in CDs and standard broadcasts. Select another
surround mode.
• Make sure that the speakers are connected correctly and the speaker cables' core wires touch
the speaker connectors.
Sound from the connected turntable is very soft.
• Check to see if the turntable has an internal phono equalizer.
If it does not have a phono equalizer, obtain an optional one.
Playing a record on the turntable does not produce sound.
• If you are using a turntable with an MC cartridge, you will need a transformer or head amplifier to boost the
voltage, and a phono equalizer.
Disc playback
The disc will not play.
• Make sure that the disc has been loaded on the disc tray correctly.
The disc should be inserted with the playback side facing down.
• Check to see if the disc surface is dirty.
• Make sure that the disc type is supported by the unit.
• If the unit displays "Wrong Region No," the unit does not support the region number
and cannot play the disc.
• Parental lock is applied. Release the lock or change the lock level.
• If condensation is suspected, wait for about one hour after you turn on the power to the unit.
The disc will not play tracks in order.
• Cancel special playback modes, such as Repeat playback, Memory playback, and Random playback.
Setup
The setting window does not appear.
• Turning on the power to the PDR-155 does not activate the DVD section. Insert a DVD disc,
press PLAY, then press STOP. Then proceed to the settings.
The settings are erased.
• The power outage or removal of the power cable may erase the settings.
The settings cannot be changed.
• If the DVD mark appears on the screen, you have tried to set an item that is only available for DVDs,
while an audio CD, video CD, or MP3 file disc is in the tray.
• Some settings cannot be changed during playback. First, stop playback, then try again.
The Setup window does not display the desired setting item.
• [Setup Menu Mode] has been set to [Basic]. Change it to [Expert].
Picture
Playback images are sometimes distorted.
• Depending on the compatibility with a TV that supports progressive picture, the progressive image may be
affected. In this case, select Interlace mode. You can still watch progressive images on TV.
• Check to see if the disc surface is dirty.
• The first forward or backward operation may cause distortion. This is not a malfunction.
