Do not hang up the monitor above a central heating or other heating sources.
Clean the anti-reflex coated flat glass screen with a slightly damp soft cloth. Do not
use abrasives solvents as it can damage the glass surface of the screen.
: A video source (such as a video game, DVD, or video information
Caution
channel) which shows a constant non-moving pattern on the monitor screen, can
cause damage to the screen.When your Flat-Monitor is continuously used with
such a source, the pattern of the non-moving portion of the game (DVD, etc.)
could leave an image permanently on the screen.When not in use, turn the video
source .
Off
Regularly alternate the use of such video sources with normal viewing.
When switching over to another picture after having displayed the same still
picture for a long time (many hours), it may happen that some parts from the
previous picture will remain on screen due to a kind of memory effect.This ghost
picture will disappear after some time.To avoid this effect change the pictures
regularly or for PC use you can turn on a screen saver in your computer.
Philips has built in an automatic shift of the picture in video mode every 5 minutes
to avoid this effect and to prolong the life of the screen.
Very incidentally and after a longer period of unuse (approx. 1 year) the screen
may display some strange colour deficiencies.This is quite normal for plasma
displays and these effects will disappear after the set has been turned on for some
time.
A plasma display consists of a high number of colour pixels. It is within industry
standards that very few pixels (< 0.001%) may be defective, even for a new set.
There is however no reason to doubt about the quality of the set.
The plasma display technology operates with rare gases which are being influenced
by air pressure.
Up to an altitude of 2000 m above sea-level (local air pressure equal or above
800 hPa), the display is functioning fine. Operating the set at a higher altitude
(lower air pressure), the picture becomes unstable and the picture performance is
deteriorating.The plasma display might then also produce a humming sound.
Bringing the set below 2000 m (local air pressure equal or above 800 hPa) it works
fine again.Transportation has no influence.
The infrared radiation of the screen may influence the reception sensitivity of
other peripherals. Solution: replace the batteries of the remote control or change
position of other equipment. E.g. keep away a wireless headphone from within a
radius of 1,5 m.
Keep the original packaging to transport the monitor if needed.
• Have you selected the correct TV system in the manual installation menu?
• Is your TV or house aerial located too close to loudspeakers, non-earthed audio
equipment or neon lights, etc.?
• Mountains or high buildings can cause double pictures or ghost images.
Sometimes you can improve the picture quality by changing the direction of the
aerial.
• Is the picture or teletext unrecognisable? Check if you have entered the correct
frequency. See Installation, Manual installation, p. 6.
• Are brightness, sharpness and contrast out of adjustment? Select Factory settings in
the Setup, General menu, p. 8.
