Tips
Poor reception
The proximity of mountains or high
buildings may be responsible for ghost
pictures, echoing or shadows. In this case,
try manually adjustingyour picture: see
Fine Tuning (p. 6) or modify the orienta-
tion of the outside aerial. Does your
antenna enable you to receive broadcasts
in this frequency range (UHF or VHF
band)? In the event of difficult reception
(snowy picture) switch the NR on the
Picture menu to ON (p. 7).
No picture
If the television does not switch on, press
the standby key (located on the
remote control) twice. Have you
connected the aerial socket properly?
Have you chosen the right system? (p. 6).
Poorly connected euroconnector cables
or aerial sockets are often the cause of
picture or sound problems (sometimes
the connectors can become half discon-
nected if the TV set is moved or turned).
Check all connections.
No sound
If on certain channels you receive a
picture but no sound, this means that you
do not have the correct TV system.
Modify the System setting (p. 6).
Colour patches on screen
Switch off the TV by the mains power
button and wait for about 20 minutes
before switching on again.
Good picture but no sound
Try to increase the volume level. Check
that the sound is not set to “mute”. If it is,
press the key to restore the sound.
Good sound but poor colour or no
picture
Try to increase the contrast and
brightness setting.
Snowish picture and noise
Check antenna connection at the rear of
the TV.
Horizontal dotted lines
Possible electrical interference e.g.
hairdryer, vacuum cleaner, etc. Switch off
the appliances.
Double or “Ghost” images
Possible poor positioning of antenna.
Usinga high directional antenna may
improve reception.
Peripheral equipment gives a black and
white picture
You have not selected the socket
connection to the right channel with the
key: for example, AV1 in socket
connection should select channel AV1 to
placback. To play a video cassette, check
that it has been recorded under the same
standard (PAL, SECAM, NTSC) which can
be replayed by the video recorder.
The remote control does not work
Check that the batteries are the right
way round and there is no obstruction
between the remote control and the TV.
If the light indicator on the set no longer
flashes when you use the remote control,
replace the batteries.
