Your LCD TV when used as a computer display through DVI and/or VGA connection
provides a self-test feature that allows you to check whether your LCD TV is
functioning properly. If your LCD TV and computer are properly connected but
the LCD TV screen remains dark, run the LCD TV self-test by performing the following
steps:
Turn off both your computer and the LCD TV.
Unplug the video cable from the back of the computer. To ensure proper Self-Test
operation, remove both Digital(white connector) and the Analog(blue connector)
cables from the back of computer.
Turn on the LCD TV.
The floating 'Dell - self-test Feature
Check' dialog box should appear on-screen (against a black background)
if the LCD TV cannot sense a video signal and is working correctly.
While in self-test mode, the power LED remains green and the self-test
pattern will scroll through the screen continually.
This box also appears during normal system operation if the video
cable becomes disconnected or damaged.
Turn off your LCD TV and reconnect the video cable; then turn on both your
computer and the LCD TV.If your LCD TV screen remains blank after you use
the previous procedure, check your video controller and computer system; your
LCD TV is functioning properly.

and Audio Problems
COMMON SYMPTOMS
WHAT YOU EXPERIENCE
POSSIBLE SOLUTIONS
Poor TV signal reception
Abnormal picture seen from the screen
The proximity of mountains or high buildings
may be responsible for ghost pictures, echoing or shadows. In this case,
try manually adjusting your pictures: see 'fine tuning' or adjust the
direction of the outside aerial.
For Asia users in non-NTSC area: Does your antenna enable you to receive
broadcasts in this frequency range (UHF or VHF band)? In the event of
difficult reception (snowy pictures) switch the NR on the PICTURE menu
to ON.
No TV picture
No picture when TV input was selected
Have you connected the aerial socket properly? Have
you chosen the right system? Poorly connected SCART cables or aerial
sockets are often the cause of picture or sound problems (sometimes
the connectors can become half disconnected if the LCD TV set is moved
or turned). Check all connections.
No sound
No sound output when a program with sound was playing
Ensure that the audio cables are firmly connected to
both the audio input connectors on your LCD TV and audio output connectors

If on certain TV channels you receive a picture but

the SYSTEM setting.
