Important Safety Notice
FOR PRODUCTS CONTAINING LASER : DANGERInvisible laser radiation when open. AVOID DIRECT EXPOSURE TO BEAM. Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. The use of optical instruments with this product will increase eye hazard.
Proper service and repair is important to the safe, reliable operation of all Philips Consumer Electronics 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 servicer 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 Consumer Electronics Company will be referred to as Philips.

Pixel Defect Policy
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:
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.
One dark sub pixel Proximity of Pixel Defects
Two or three adjacent dark sub pixels
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. ACCEPTABLE BRIGHT DOT DEFECTS LEVEL 1 lit subpixel 2 adjacent lit subpixels 3 adjacent lit subpixels (one white pixel) Distance between two bright dot defects* Total bright dot defects of all types 3 or fewer 1 or fewer 0 25 mm or more 3 or fewer
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'. These are the types of bright dot defects:
ACCEPTABLE BLACK DOT DEFECTS LEVEL 1 dark subpixel 2 adjacent dark subpixels 3 adjacent dark subpixels Distance between two black dot defects* Total black dot defects of all types 5 or fewer 2 or fewer 0 15 mm or more 5 or fewer ACCEPTABLE TOTAL DOT DEFECTS LEVEL
Two adjacent lit sub pixels: - Red + Blue = One lit red, green or Purple blue sub pixel - Red + Green = Yellow - Green + Blue = Cyan (Light Blue)
Total bright or black dot defects of all
Three adjacent lit sub pixels (one white pixel)
5 or fewer types
Note: * 1 or 2 adjacent sub pixel defects = 1 dot defect All Philips monitors are ISO13406-2 Compliant

General points
During the test and measuring, supply a distortion free AC mains voltage to the apparatus via an isolated transformer with low internal resistance. All measurements mentioned hereafter are carried out at a normal mains voltage (90 - 132 VAC for USA version, 195 -264 VAC for EUROPEAN version, or 90 - 264 VAC for the model with full range power supply, unless otherwise stated.) All voltages are to be measured or applied with respect to ground, unless otherwise stated. Note: don` use heat-sink as ground. t The test has to be done on a complete set including LCD panel after 30 minutes warm-up at least in a room with temperature of 25 +/- 5 degree C. All values mentioned in these test instruction are only applicable of a well aligned apparatus, with correct signal. The letters symbols (B) and (S) placed behind the test instruction denotes (B): carried out 100% inspection at assembly line (S): carried out test by sampling The white balance (color temperature) has to be tested in subdued lighted room. Repetitive power on / off cycle are allowed except it should be avoided within 6 sec.

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, & 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.

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).
Configuration and procedure
There are 3 chips contained OSD string, serial number..etc on the circuit board, main EEPROM which storage all factory settings,OSD string. DDC IC which storage 128byte EDID data(serial number ..etc.). Following descirptions are the connection and procedure for Analog /Digital and main EEPROM can be re-programmed along with Analog/Digital IC by enable factory memory data write function on the DDC program (EDID45.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 or using batteries. Step 2: Connecting printer cable and D-Sub cable of monitor as Fig. 4
