TROUBLESHOOTING GUIDE
SOLUTION
• Check AC power plug and make certain any switched
outlet is turned on.
• Load disc label-side up; align the disc with the guides and place
it in its proper position.
• Check to see that the disc is CD, CD-R, CD-RW, VCD, MP3, WMA, JPEG,
DVD-R, DVD-RW, DVD+R, DVD+RW (standard-conforming), DVD-Audio
or DVD-Video; other types will not play.
• Use Region 1 or Open Region (0) disc only.
• Enter password to override or change rating settings (see page 20).
• Check all video connections.
• Check input selection of TV or receiver.
• Use Progressive Scan mode only with compatible TV. Press Progressive Scan/
Interlaced Button I to toggle to the correct mode (see page 23).
• Press Video Off Button F to reactivate video circuitry.
• The HDMI Output 2 may not be used with video displays that are not
HDCP-compliant. Unplug the cable and select another audio and video
connection (see pages 14 through 16).
• S- and component video are not available simultaneously. Temporarily connect
composite video to access VIDEO SETUP menu and change
VIDEO OUTPUT setting to desired type (see page 23).
• Check all audio connections.
• Check digital audio settings on DVD 37 and on receiver.
• There is no audio playback on DVD discs during fast or slow modes.
• Change PCM LIMIT setting in AUDIO SETUP menu to 48kHz
(see page 22).
• Use 6-Channel Audio Outputs 9 or Analog Audio Outputs 8.
• In order to hear a downmixed 2-channel signal at the Analog Audio Outputs
8, make sure to change the BASS MANAGEMENT setting to
STEREO (see pages 12 and 22).
• It is a normal artifact of DVD playback for pictures to jump or show
some distortion during rapid play.
• With most discs, some functions are not permitted at certain
times (e.g., Track Skip) or at all (e.g., direct audio track selection).
• Change the display language selection (see page 23).
• Certain functions may be disabled by the DVD itself during
passages of a disc.
• Change aspect ratio settings (see page 23).
• Change both batteries.
• Clear path to sensor or use optional outboard remote sensor.
• Many DVDs are encoded with copy protection to prevent
copying to VCR.
• Stop play of disc. Press and hold Clear Button 3 until the display blinks.
This resets the password and all settings to their defaults.
