Important Safety Notice

Proper service and repair is important to the safe, reliable operation of all Philips Company Equipment. The service

procedures recommended by Philips and described in this service manual are effective methods of performing

service operations. Some of these service operations require the use of tools specially designed for the purpose.

The special tools should be used when and as recommended.

It is important to note that this manual contains various CAUTIONS and NOTICES which should be carefully read

in order to minimize the risk of personal injury to service personnel. The possibility exists that improper service

methods may damage the equipment. It is also important to understand that these CAUTIONS and NOTICES ARE

NOT EXHAUSTIVE. Philips could not possibly know, evaluate and advise the service trade of all conceivable ways

in which service might be done or of the possible hazardous consequences of each way. Consequently, Philips has

not undertaken any such broad evaluation. Accordingly, a customer who uses a service procedure or tool which is

not recommended by Philips must first satisfy himself thoroughly that neither his safety nor the safe operation of

the equipment will be jeopardized by the service method selected.

Hereafter throughout this manual, Philips Company will be referred to as Philips.

WARNING

Use of substitute replacement parts, which do not have the same, specified safety characteristics, may create

shock, fire, or other hazards.

Under no circumstances should the original design be modified or altered without written permission from Philips.

Philips assumes no liability, express or implied, arising out of any unauthorized modification of design.

FOR PRODUCTS CONTAINING LASER:

DANGER- There is invisible laser radiation when open. AVOID DIRECT EXPOSURE TO BEAM.

CAUTION-Use of controls or adjustments or performance of procedures other than those specified herein may

result in hazardous radiation exposure.

CAUTION -The use of optical instruments with this product will increase eye hazard.

TO ENSURE THE CONTINUED RELIABILITY OF THIS PRODUCT, USE ONLY ORIGINAL MANUFACTURER'S

REPLACEMENT PARTS, WHICH ARE LISTED WITH THEIR PART NUMBERS IN THE PARTS LIST SECTION

OF THIS SERVICE MANUAL.

Take care during handling the LCD module with backlight unit:

-Must mount the module using mounting holes arranged in four corners.

-Do not press on the panel, edge of the frame strongly or electric shock as this will result in damage to the screen.

-Do not scratch or press on the panel with any sharp objects, such as pencil or pen as this may result in damage to

the panel.

-Protect the module from the ESD as it may damage the electronic circuit (C-MOS).

-Make certain that treatment person’s body is grounded through wristband.

-Do not leave the module in high temperature and in areas of high humidity for a long time.

-Avoid contact with water as it may a short circuit within the module.

-If the surface of panel becomes dirty, please wipe it off with a soft material. (Cleaning with a dirty or rough cloth

may damage the panel.)

4.3 Pixel Defect Policy

defects and several types of sub pixel defects within

Philips strives to deliver the highest quality products.

We use some of the industry’s most advanced

manufacturing process 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

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

21.5″ XGA monitor may be defective. Furthermore,

Philips sets even higher quality standard for certain

each category.

Bright Dot Defects Bright dot defects appear as pixels

or sub pixels that are always lit or ‘on’. That is, a Bright

dot is a sub-pixel that stands out on the screen when

the monitor displays a dark pattern. There are three

types of bright dot defects:

One lit red, green or blue sub pixel

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 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

Two adjacent lit sub pixels:

- Red + Blue = Purple

- Red + Green = Yellow

- Green + Blue = Cyan (Light Blue)

Three adjacent lit sub pixels (one white pixel)

signal black pixel. Other combinations of lit and dark

sub 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

Note:

A red or blue bright dot must be more than 50 percent

brighter than neighboring dots while a green bright dot

is 30 percent brighter than neighboring dots.

Meridian 2

13

Black Dot Defects Black dot defects appear as pixels

or sub pixels that are always dark or ‘off’. That is, a

dark dot is a sub-pixel that stands out on the screen

when the monitor displays a light pattern. There are

two types of black dot defects:

Proximity of Pixel Defects

Because pixel and sub pixels defects of the same type

that are near to one another may be more noticeable,

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

1 lit subpixel 3

2 adjacent lit subpixels 1

3 adjacent lit subpixels (one white pixel) 0

Distance between two bright dot defects* >15mm

Total bright dot defects of all types 3

Black Dot Defects Acceptable level

1 dark subpixel 5 or fewer

2 adjacent dark subpixels 2 or fewer

3 adjacent dark subpixels 0

Distance between two black dot defects* >15mm

Total black dot defects of all types 5 or fewer

Total Dot Defects Acceptable level

Total bright or black dot defects of all types 5 or fewer

Note:

1. 1 or 2 adjacent sub pixel defects = 1 dot defect.

2. This monitor is ISO9241-307 compliant (ISO9241-307: Ergonomic requirement, analysis and compliance test
