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 pro blems
after checking your connecti ons, 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 20).

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 compo-

nents.

• The plugs and jacks are dirty. Wipe them with a

cloth slightly moistened with alcohol.

• Clean the disc.

The surround effect is difficult to hear
when you are playing a Dolby Digital
sound track.
• Check to see if the Dolby Digital mode is

turned on properly, other wise unload and load
the disc again.

• Check the speaker connections.

• Depending on the DVD disc, the output signal

may at times be mono or stereo even if the
soundtrack is recorded in Dolby Digital format.

The sound comes from the center speaker
only.
• Depending on the disc, sound may sometimes

come from the center speaker only. This also
applies to mono recordings (from disc or any
analog source), when Pro Logic mode is
 selected. This is normal.

No sound is heard from the center speaker.
• Adjust center speaker volume (see pages 20).

No sound or only very low volume from
the rear speakers.
• Adjust the rear speaker volume (see page 20).

• 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.
