Troubleshooting
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
authorized Harman Kardon dealer.
No power.
• Is the power cord firmly plugged into the
power outlet?
• One of the safety mechanisms may be
operating. 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 14).
• 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 problems
after checking your connections, please try
connecting your DVD system directly to your
TV’s S-Video input, if your TV is equipped with
this input (see page 14).
The aspect ratio of the screen is wrong
(picture vertically expanded) when you
play a wide picture even though you set
“TV DISPLAY” in the SETUP menu to
"16:9".
• If you connect the system 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 HS, or if the autoswitch function does
not work you should turn the TV to "16:9" (if
possible with your TV).
• Depending on the TV, you may not be able to
change the aspect ratio. In that case (TV not
adjustable to 16:9) do not select "16:9" in the
TV Display. Then, no change of the aspect ratio
is needed.
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.
Press 
N
to return to normal play mode.
• Check the speaker settings (see page 19).
The left and right channels are unbalanced
or reversed.
• Check that the speakers and components are
connected correctly and securely.
Severe hum or noise is heard.
• Check that the speakers and components are
connected securely.
• Check that the connecting cords are away from
a transformer or motor and at least 3 meters
away from fluorescent light.
• Move your TV away from the audio
components.
• The plugs and jacks are dirty. Wipe them with a
cloth slightly moistened with alcohol.
• Clean the disc.
The volume goes down automatically 
and can not be increased.
• The internal temperature is too high. Wait
approximately one minute for the amplifier to
reach normal working temperature.
Radio stations cannot be tuned in.
• Check that the antenna is connected correctly.
Adjust the antenna and connect an external
antenna if necessary.
• The signal strength of the stations is too weak
for automatic tuning. Use manual tuning.
• No stations have been preset.
• The tuner mode is not selected, select the
Radio mode.
The remote does not function.
• Remove any obstacles between the remote
control and the system.
• Move the remote control closer to the system.
• Point the remote control at the remote sensor
on the front panel.
• Replace all the batteries in the remote control
with new ones if they are weak.
• Check that the batteries are loaded correctly.
The disc does not play.
• There is no disc inside. (“NO DISC” appears on
the front panel display and the TV screen.)
Insert a disc.
• Insert the disc correctly with the playback side
facing down on the disc tray.
• Clean the disc.
• The system cannot play CD-ROM's, etc.
(see page 3).
• DVD with wrong region code 
(see page 13).
The system starts playing the DVD
automatically.
• The DVD features the auto playback function.
Playback stops automatically.
• Some discs include an auto pause signal. When
playing such a disc, the system stops playback
at the signal.
