Proper service and repair isimportant to the safe, reliable

operation of all HPConsumer Electronics Company**

Equipment. The service procedures recommended by HP and

described in this service manual are effective methods of

performing service operations. Some ofthese 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. HP 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, HP has not

undertaken any such broad evaluation. Accordingly, a

servicer who uses a service procedure or tool which is not

recommended by HP 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, HP Consumer

Electronics Company will bereferred to as HP.

Critical components having special safety characteristics are

identified with a bythe Ref. No. inthe parts list and

enclosed within a broken line*

Philips Pixel Defect Policy

200WB7 LCD

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.

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 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

1 lit subpixel

2 adjacent lit subpixels

pixel)

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 ACCEPTABLE LEVEL

MODEL

An after-image appears

An after-image remains after the power has been turned off.

Green, red, blue, dark, and white dots Remains

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 afterimage. 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 peroid of time.

The remaining dots are normal characteristic of the liquid crystal used in today's technology.

General

DDC Data Re-programming In case the DDC data memory IC or main EEPROM which storage all factory settings were replaced due to a defect, the serial numbers have to be re-programmed "Analog DDC IC, Digital DDC IC & EEPROM". It is advised to re-soldered DDC IC and main EEPROM from the old board onto the new board if circuit board have been replaced, in this case the DDC data does not need to be re-programmed.

Additional information Additional information about DDC (Display Data Channel) may be obtained from Video Electronics Standards Association (VESA). Extended Display Identification Data(EDID) information may be also obtained from VESA.

System and equipment requirements

1. An i486 (or above) personal computer or compatible.

2. Microsoft operation system Windows 95/98 . Y o Install the EDID_PORT_Tool under Win2000/XP . As

DDC Instructions

Configuration and procedure

There is no Hardware DDC (DDC IC) anymore. Main EEPROM stores

all factory settings and DDC data (EDID code) which is also called Software DDC. The following section describes the connection and procedure for Software DDC application. The main EEPROM can be reprogrammed by enabling '' factory memory data write'' function on the DDC program (EDID46.EXE).

Initialize alignment box

In order to avoid that monitor entering power saving mode due

to sync will cut off by alignment box, it is necessary to initialize

alignment box before running programming software

(EDID46.EXE). Following steps show you the procedures and

connection.

Step 1: Supply 8-12V DC power source to the Alignment box by

plugging a DC power cord .

Step 2: Connecting printer cable and D-Sub cable of monitor as Fig. 4

1= Power connector 2= D-SUB connector

3. At the submenu, type the letter of your computer's hard disk drive followed by :EDID46 (for example, C:\EDID46, as shown in Fig. 6).

4. Click OK button. The main menu appears (as shown in Fig. 7).

This is for initialize alignment box.

Step 3: Installation of EDID46.EXE

Method 1: Start on DDC program

Start Microsoft Windows.

1. The Program"EDID46.EXE" in service manual cd-rom be copyed to C:\ .

2. Click , choose Run at start menu of Windows as shown In Fig. 5.

Fig. 7

Note 1: If the connection is improper, you will see the following error

message (as shown in Fig. 8) before entering the main menu.

Meanwhile, the (read EDID) function will be disable. At this

time, please make sure all cables are connected correctly and fixedly, and the procedure has been performed properly.

Fig. 8

Note 2: During the loading, EDID46 will verify the EDID data which just

loaded from monitor before proceed any further function, once the data structure of EDID can not be recognized, the following error message will appear on the screen as below. Please confirm following steps to avoid this message.

1. The data structure of EDID was incorrect.

2. DDC IC that you are trying to load data is empty.

3. Wrong communication channel has set at configuration setup windows.

4. Cables loosed or poor contact of connection.
