reconnect after several minutes.

preset stations, return to the default settings):

Problems and solutions
• The video input on your TV is not set so that you can view pictures from the
system.
• Check the output method on your system.
• The unit is connected to an input device that is not HDCP (High-bandwidth
Digital Content Protection) compliant.
• If the HDMI OUT jack is used for video output, change the type of video signal
output from the HDMI OUT jack (page 59).
Connect your TV and the unit using a video jack other than HDMI OUT, and
switch your 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 your TV's input back to HDMI. If the picture still does not
appear, repeat the Steps and try other options.
• You have set progressive format but your TV cannot accept the signal in
progressive format. In this case, return the setting to interlace format (the
default setting) (pages 30, 58).
• You have set [PROGRESSIVE (COMPONENT OUT)] in [VIDEO SETUP] to
[ON] (page 58) even though your TV cannot accept the progressive signal. In
this case, disconnect the HDMI cable from the unit and then set to [OFF].
• Even if your TV is compatible with progressive format (525p/625p) signals, the
image may be affected when you set progressive format. In this case, return the
setting to interlace format (the default setting) (pages 30, 58).
• 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. Connect the unit directly to your TV.
• Check the setting of [TV TYPE] in [VIDEO SETUP] (page 58).
• The aspect ratio on the disc is fixed.
