TV 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 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.
