The remote does not function. • The distance between the remote and the unit is too far.
• The batteries in the remote are weak.
The system does not work

reconnect after several minutes.

preset stations, return to the default settings):
1 Press "/1 to turn on the system.

Symptom Problems and solutions
There is no picture. • 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.
There is no picture when you
make an HDMI cable
connection. • 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 50).
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.
Picture noise appears. • 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]
* (page 50).
* Depending on the area, [720 × 480/576p] may appear.
An image is not displayed on the
entire TV screen. • Check the setting of [TV TYPE] in [VIDEO SETUP] (page 50).
• The aspect ratio on the disc is fixed.
Color irregularity occurs on the
TV screen. The system’s speakers contain magnet parts, so magnetic distortion may occur.
When color irregularity occurs on the TV screen, check the following items:
• Install the speakers at least 0.3 meters from your TV set.
• If the color irregularity persists, turn off your TV set once, then turn it on after
15 to 30 minutes.
• Make sure that no magnetic object (magnetic latch on a TV stand, health care
device, toy, etc.) is placed near the speakers.
• Reposition the speakers farther away from your TV set.
