TV and Audio Problems
COMMON
SYMPTOMS
WHAT YOU EXPERIENCE POSSIBLE SOLUTIONS
Poor TV signal reception
No TV picture
No sound
Abnormal picture seen from the screen
No picture when TV input was selected
No sound output when a program with
sound was playing
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.
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.
Ensure that the audio cables are firmly connected to both the audio
input connectors on your LCD TV and audio output connectors on
your PC or Video player.
If on certain TV channels you receive a picture but no sound, this
means that you do not have the correct TV system. Modify the
SYSTEM setting.
