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 ("HDMI" on the front panel does not
light up).
• If the HDMI OUT jack is used for video output, change the type of video signal
output from the HDMI OUT jack (page 63).
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.
• If the signal from the EURO AV T OUTPUT (TO TV) jack is distorted,
change the type of video signal output from the HDMI OUT jack by setting
[HDMI RESOLUTION] in [HDMI SETUP] to [720 × 480p]
* Depending on the area, [720 × 480/576p] may appear.
• Check the setting of [TV TYPE] in [VIDEO SETUP] (page 63).
• The aspect ratio on the disc is fixed.
