Important Safety Notice

Proper service and repair is important to the safe, reliable operation of all Philips Company Equipment. The servi ce
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 recommende d.
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 NOTICE S 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 pen cil or pen as this ma y 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 ground ed 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 rou gh cloth
may damage the panel.)

4.3 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
19" 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 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:

Two adjacent lit sub pixels:

- Red + Blue = Purple Three adjacent lit sub pixels
(one white pixel) One lit red, green or blue sub pixel - Red + Green = Yellow

- Green + Blue = Cyan (Light Blue)

A red or blue bright dot must be more tha n 50 percent brighter than n eighboring dots while a green bright
dot is 30 percent brighter than neighboring dots.

Black Dot Defects Black dot defect s appear as pixels or sub pixel s that are always dark or ‘off’. That is, a dark dot i s
a sub-pixel that stands out on the screen when the monitor displays a light pattern. There are two types of black d ot
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

MODEL 160EL1
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
