Troubleshooting
For the Controller
If you experience any of the following difficulties
while using the system, use this troubleshooting
guide to help you remedy the problem.
Should any problem persist, consult your author-
ized Harman Kardon dealer.
No power.
• Is the power cord firmly plugged into the
power outlet?
• One of the safety mechanisms may be operat-
ing. In this event, unplug the player from the
power outlet briefly and then plug it in again.
No picture.
• Check that the system is connected correctly
and securely.
• The video cable may be damaged. Replace it
with a new one.
• Make sure the system is connected to a video
input on the TV (see page 12).
• Make sure the TV is turned on.
• Make sure the correct video input on the TV is
selected for viewing with this system.
Noise (interference) appears in
the picture.
• Clean the disc.
• If video from this system has to go through
your VCR to get to your TV, the copy-protection
applied to some DVD programs could affect
picture quality. If you still experience pro blems
after checking your connecti ons, please try con-
necting your DVD system directly to your TV’s
S-Video input.
The aspect ratio of the screen is wrong
(picture vertically expanded) when you
play a wide picture by the player or an
external source connected to the screen
even though you set “TV DISPLAY” in the
SETUP menu to "Auto".
• If you connect the system or the external
source with the SCART cable, connect directly
to the TV. Otherwise the autoswitch function of
the aspect ratio for the TV may not work.
• If the TV is not connected with a SCART cable
to the DL (as recommended) or the external
source, or if the autoswitch function does not
work you should turn the TV to "Fill All".
There is no sound or volume is very low
• Check that the speakers and components are
connected correctly and securely.
• Make sure that you have selected the correct
source on the system.
• Press MUTE on the remote control, if the
words MUTE ON are blinking on the front
panel display.
• The protective circuitry has been activated
because of a short circuit. Turn off the system,
eliminate the short circuit problem and turn on
the power again.
• The audio interconnect is damaged. Replace it
with a new one.
• The system is in pause mode or in slow-motion
play mode, or fast forward or fast reverse.

a transformer or motor and at least 3 meters
away from fluorescent light.
• Move your TV away from the audio compo-
nents.
• The plugs and jacks are dirty. Wipe them with a
cloth slightly moistened with alcohol.
• Clean the disc.
• Disconnect antenna cables from external
sources (also PC) connected to the screen or
system. If hum disappears use an antenna
transfomer between antenna and source.
• If PC is connected to the system disconnect the
Audio and Video cables. If hum disappears use
an audio transformer between PC audio out
and system input. If hum persists unplug PC
from your system and ask your local dealer for
a proper solution (ground loop interrupt).
The volume goes down automatically
