Remedy
• The video connecting cords are not connected securely.
• The video connecting cords are damaged.
• The unit is not connected to the correct TV input jack (page 21).
• The video input on the TV is not set so that you can view pictures from the
system.
• Check the output method on your system (page 21).
• Re-connect the connecting cord securely.
• The unit is connected to an input device that is not HDCP (High-bandwidth
Digital Content Protection) compliant ("HDMI" on the front panel does not
light up) (page 21).
• If the HDMI OUT jack is used for video output, change the type of video signal
output from the HDMI OUT jack. It may solve the problem (page 27).
Connect the TV and the unit using a video jack other than the HDMI OUT, and
switch the TV's input to the connected video input so that you can see the on-
screen displays. Change the type of video signal output from the HDMI OUT
jack, and switch the TV's input back to HDMI. If the picture still does not
appear, repeat the Steps and try other options.
• The disc is dirty or flawed.
• If the picture output from your system goes through your VCR to get to your
TV, the copy-protection signal applied to some DVD programs could affect
picture quality. If you experience problems when you connect your unit through
your VCR, try connecting your unit to your TV's video input directly (page 21).
• The aspect ratio on the disc is fixed.
