JBL CS3 - Manual (Page 32)

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
JBL 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.
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 CS, 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 A on the remote control, if the words MUTE O N
are blinking in the front-panel display.
• The protective circuitry has been activated because of a short
circuit. Turn the system off, eliminate the short circuit problem
and turn the power on 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 audio 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 surround effect is difficult to hear when you are playing a
Dolby Digital soundtrack.
• Check to see whether the Dolby Digital mode is turned on
properly; otherwise, 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 page 20).
No sound or only very low volume from the rear speakers.
• Adjust the rear speaker volume (see page 20).
The volume goes down automatically and cannot 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.
