Tips
Poor reception
The proximity of mountains or high buildings
may be responsible for ghost pictures, echoing
or shadows. In this case, try manually adjusting
your picture: see Fine Tuning (p.5) or modify
the orientation 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 Options
menu to ON. (p. 6).
No picture
If the television does not switch on, please
press the standby key
remote control) twice.
Have you connected the aerial socket properly?
Have you chosen the right system? (p. 5).
Poorly connected euroconnector cables or
aerial sockets are often the cause of picture or
sound problems (sometimes the connectors
can become half disconnected if the TV set is
moved or turned). Check all connections.
Peripheral equipment gives a black and
white picture
You have not selected the right socket with the
n
key: S-VHS2 instead of EXT2.
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 no longer works.
Check that the mode selector on the side of
the remote control is set to TV.

Glossary

RGB Signals: These are 3 Red, Green and Blue video signals which directly drive the red, green and
blue emitters in the cathode ray tube. Using these signals provides better picture quality.
S-VHS Signals: These are 2 separate Y/C video signals from the S-VHS and Hi-8 recording standards.
The luminance signals Y (black and white) and chrominance signals C (colour) are recorded
separately on the tape.This provides better picture quality than with standard video (VHS and 8
mm) where the Y/C signals are combined to provide only one video signal.
NICAM sound: Process by which digital sound can be transmitted.
System: Television pictures are not broadcast in the same way in all countries.There are different
standards: BG, DK, I, and L L'.The SYSTEM setting (p. 6) is used to select these different standards.
This is not to be confused with PAL or SECAM colour coding. Pal is used in most countries in
Europe, Secam in France, Russia and most African countries.The United States and Japan use a
different system called NTSC.The inputs EXT1 and EXT2 are used to read NTSC coded recordings.
16:9: Refers to the ration between the length and height of the screen.
Wide screen televisions have a ration of 16/9, conventional screen TV sets have a ration of 4/3.

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. 5).
Teletext
Are certain characters not displayed
correctly? Check that the Country setting
has been positioned correctly (p.5).
Remote control
The TV set does not react to the remote
control; the indicator on the set no longer
flashes when you use the remote control?
Replace the batteries.
Standby
When you switch the TV set on it remains in
standby mode and the indication Locked is
displayed when you use the keys on the TV set?
The Child Lock function is switched On (p. 7).
If the set receives no signal for 15 mins, it
automatically goes into standby mode.
To save power, your set is fitted with components
that give it a very low power consumption when
in standby mode (less than 3 W).
Still no results?
If your TV set breaks down, never attempt to
repair it yourself: contact your dealer's after-
sales service.
Cleaning the set
Only use a clean, soft and lint-free cloth to
clean the screen and the casing of your set.
Do not use alcohol-based or solvent-based
products.
