sRGB is a standard
SRGB
for ensuring correct exchange of colors between
different devices (e.g. digital cameras, monitors, printers, scanners, etc.)
Using a standard unified color space, sRGB will help represent pictures
taken by an sRGBcompatible device correctly on your sRGB enabled
Philips monitors. In that way, the colors are calibrated and you can rely
on the correctness of the colors shown on your screen.
Important with the use of sRGB is that the brightness and contrast of
your monitor is fixed to a predefined setting as well as the color gamut.
Therefore it is important to select the sRGB setting in the monitor's OSD.
To do so, open the OSD by pressing the OKbutton on the front of your
monitor. Use the down button to go to Adjust Color and press OKagain.
Then move the down button to go to sRGB and press OKagain.
After this, please do not change the brightness or contrast setting of your
monitor. If you change either of these, the monitor will exit the sRGB
mode and go to a color temperature setting of 6500K.
For more information on sRGB, please visit: www.srgb.com

Philips Pixel Defect Policy
Philips' Flat Panel Monitors Pixel Defect Policy
Philips strives to deliver the highest quality products. We
use some of the industry's most advanced manufacturing
processes and practice stringent quality control. However,
pixel or sub pixel defects on the TFT LCD panels used in
flat panel monitors are sometimes unavoidable. No
manufacturer can guarantee that all panels will be free
from pixel defects, but Philips guarantees that any monitor
with an unacceptable number of defects will be repaired or
replaced under warranty. This notice explains the different
types of pixel defects and defines acceptable defect levels
for each type. In order to qualify for repair or replacement
under warranty, the number of pixel defects on a TFT LCD
panel must exceed these acceptable levels. For example,
no more than 0.0004% of the sub pixels on a 15" XGA
monitor may be defective. Furthermore, Philips sets even
higher quality standards for certain types or combinations
of pixel defects that are more noticeable than others. This
policy is valid worldwide.
Pixels and Sub pixels
A pixel, or picture element, is composed of three sub pixels
in the primary colors of red, green and blue. Many pixels
together form an image. When all sub pixels of a pixel are lit,
the three colored sub pixels together appear as a single
white pixel. When all are dark, the three colored sub pixels
together appear as a single black pixel. Other combinations
of lit and dark sub pixels appear as single pixels of other
colors.
Types of Pixel Defects
Pixel and sub pixel defects appear on the screen in different
ways. There are two categories of pixel defects and several
types of sub pixel defects within each category. Bright dot
defects appear as pixels or sub pixels that are always lit or
'on'. These are the types of bright dot defects:
One lit red,
green or
blue sub pixel
Two adjacent lit
sub pixels:
- Red +Blue =Purple
- Red +Green =Yellow
- Green +Blue =Cyan
(Light Blue)
Three adjacent lit
sub pixels
(one white pixel)
Black Dot Defects Black dot defects appear as pixels or sub
pixels that are always dark or 'off'. These are the types of black
dot defects:
One dark sub pixel Two or three adjacent dark sub pixels
Proximity of Pixel Defects
Because pixel and sub pixels defects of the same type that are
near to one another may be more , Philips also
specifies tolerances for the proximity of pixel defects.
Pixel Defect Tolerances
In order to qualify for repair or replacement due to pixel defects
during the warranty period, a TFT LCD panel in a Philips flat panel
monitor must have pixel or sub pixel defects exceeding the
tolerances listed in the following tables.
BRIGHT DOT DEFECTS ACCEPTABLE LEVEL
MODEL 150C5
1lit subpixel 4or fewer
2 adjacent lit subpixels 2 or fewer
3 adjacent lit subpixels (one white
pixel) 0
Distance between two bright dot
defects* 15 mm or more
Total bright dot defects of all types 4 or fewer
BLACKDOT DEFECTS ACCEPTABLE LEVEL
MODEL 150C5
1dark subpixel 4or fewer
2 adjacent dark subpixels 2 or fewer
3 adjacent dark subpixels 1or fewer
Distance between two black dot defects* 15 mm or more
Total black dot defects of all types 4or fewer
TOTAL DOT DEFECTS ACCEPTABLE LEVEL
MODEL 150C5
Total bright or black dot defects of all
types 5or fewer
Note:
*1or 2 adjacent sub pixel defects =1dot defect
All Philips monitors are ISO13406-2 Compliant

Repair Tips
0. Warning
All ICs and many other semi-conductors are susceptible to
electrostatic discharges (ESD). Careless handling during
repair can reduce life drastically. When repairing, make sure
that you are connected with the same potential as the mass
of the unit via a wrist wrap with resistance. Keep components
and tools also at the same potential !
1. Servicing of SMDs (Surface Mounted Devices)
1.1General cautions on handling and storage
- Oxidation on the terminals of SMDs results in poor soldering.
Do not handle SMDs with bare hands.
- Avoid using storage places that are sensitive to oxidation
such as places with sulphur or chlorine gas, direct sunlight,
high temperatures or a high degree of humidity. The
capacitance or resistance value of the SMDs may be
affected by this.
- Rough handling of circuit boards containing SMDs may
cause damage to the components as well as the circuit
boards. Circuit boards containing SMDs should never be
bent or flexed. Different circuit board materials expand and
contract at different rates when heated or cooled and the
components and/or solder connections may be damaged
due to the stress. Never rub or scrape chip components as
this may cause the value of the component to change.
Similarly, do not slide the circuit board across any surface.
1.2 Removal of SMDs
- Heat the solder (for 2-3 seconds) at each terminal of the
chip. By means of litz wire and a slight horizontal force,
small components can be removed with the soldering iron.
They can also be removed with a solder sucker (see Fig.
1A)
-While holding the SMD with a pair of tweezers, take it off
gently using the soldering iron's heat applied to each
terminal (see Fig. 1B).
- Remove the excess solder on the solder lands by means of
litz wire or a solder sucker (see Fig. 1C).
1.3 Caution on removal
-When handling the soldering.iron. use suitable pressure and
be careful.
-When removing the chip, do not use undue force with the
pair of tweezers.
-Thesolderingirontobeused(approx.30W) should

Preferably be equipped with a thermal control
(soldering temperature: 225 degree V to 250 degree C.
-The chip, once removed, must never be reused.
-Locate the SMD on the solder lands by means of tweezers
and solder the component on one side. Ensure that the
component is positioned correctly on the solder lands (see Fig. 2A)
-Next complete the soldering of the terminals of the component.
(See Fig. 2B)
1.4 Attachment of SMDs
2. Caution when attaching SMDs
-When soldering the SMDs terminals, do not touch them
directly with the soldering iron. The soldering should be
directly with the soldering iron. The soldering should be
done as quickly as possible, care must be taken to avoid
damage to the terminals of the SMDs themselves.
- Keep the SMD's body in contact with the printed board
when soldering.
- The soldering iron to be used (approx. 30W) should
preferably be equipped with a thermal control (soldering
temperature: 225 degree C to 250 degree C).
- Soldering should not be done outside the solder land.
- Soldering flux (of rosin) may be used, but should not
be acidic.
- After soldering, let the SMDs cool down gradually at room
temperature.
- The quantity of solder must be proportional to the size of
the solder land. If the quantity is too great, the SMD might
crack or the solder lands might be torn loose from the
printed board (See Fig. 3).
