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 Tune (p. 6) or modify the orientation of the outside aerial. If you are using an
	indoor aerial, reception may be difficult in certain conditions.You can improve
	reception by rotating the aerial. If the reception remains poor, you will need to
	use an external aerial
No picture	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 disconnected 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).
	The amplifier connected to the TV does not deliver any sound? Check that you
	have not confused the audio output with the audio input.
PC mode doesn’t	Check that you have configured the computer on a compatible display resolution
work ?	(see p. 13).
Snowy picture	Noise is displayed if the connected digital equipment’s (DVD player or set-top
when switched to	box) HDCP authentication failed. Check the user manual for the digital
HD-D mode	equipment you are connecting.
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 battery.
Standby	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 1 W).
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.
Still no results?	Disconnect the mains plug of the TV for 30 seconds then reconnect it.
	If your TV set breaks down, never attempt to repair it yourself: contact your
	dealer's after-sales service.

Glossary

DVI (Digital Visual Interface):A digital interface standard created by the Digital Display Working Group (DDWG) to convert analog signals into digital signals to accommodate both analog and digital monitors.

HDCP (High-bandwidth Digital-Content Protection): developed by Intel to provide secure copy protection of content transmitted digitally from the source (such as DVD player or set-top box) to the TV display.

VGA (Video Graphics Array): a common standard graphics display system for PCs.

RGB signals : These are the three video signals, Red Green Blue, which make up the picture. Using these signals improves 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.
