SRGB

sRGB is a standard 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 OK button on the front of your monitor. Use the down button to go to Adjust Color and press OK again. Then move the down button to go to sRGB and press OK again.

Philips Pixel Defect Policy

Go to cover page

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.

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 D efects

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.

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)

BRIGHT DOT DEFECTS ACCEPTABLE LEVEL

MODEL

1 lit subpixel 4 or fewer

2 adjacent lit subpixels 2 or fewer

3 adjacent lit subpixels (one white

pixel)

· Adjust the contrast and brightness on OSD Main Controls. (The

backlight of the LCD monitor has a fixed life span. When the screen becomes dark or begins to flicker, please contact your dealer).

· If an image remains on the screen for an extended period of time,

it may be imprinted in the screen and leave an after-image. This usually disappears after a few hours.

· This is characteristic of liquid crystal and is not caused by a

malfunction or deterioration of the liquid crystal. The after-image will disappear after a period of time.

· The remaining dots are normal characteristic of the liquid crystal

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)

1.1 General 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)

SOLDERING IRON

E.g. WELLER

SOLDER TIP PT-H7

SOLDER WICK 4822 321 40042

SOLDERING IRON

SOLDER WICK

- 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. 1 B).

- Remove the excess solder on the solder lands by means of litz wire or a solder sucker (see Fig. 1C).

E.g. A PAIR OF TWEEZERS

HEATING

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 tweez ers.

-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.

1.4 Attachment of SMDs

-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)

E.g. A PAIR OF TWEEZERS

SOLDERING TIME < 3 sec/side

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).
