Pixel Defect Policy
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 subpixel 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 subpixels on a 15" XGA monitor may be defective. Additionally, because some types or combinations of pixel defects are more noticeable than others, Philips sets even higher quality standards for those. Black Dot Defects

170B4&S4 11 Go to cover page

Black dot defects appear as pixels or subpixels that are always dark or "off". These are the types of black dot defects:

One dark subpixel

Two or three adjacent dark subpixels Proximity of Pixel Defects Because pixel and subpixels defects of the same type that are nearby 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 subpixel defects exceeding the tolerances listed in the following tables. BRIGHT DOT DEFECTS MODEL 1 lit subpixel 2 adjacent lit subpixels 3 adjacent lit subpixels (one white pixel) Distance between two bright dot defects* Bright dot defects within 20 mm circle Total bright dot defects of all types ACCEPTABLE LEVEL 170B4&S4 3 or fewer 1 or fewer 0 15 mm or more 3 or fewer

Pixels and Subpixels A pixel, or picture element, is composed of three subpixels in the primary colors of red, green and blue. Many pixels together form an image. When all subpixels of a pixel are lit, the three colored subpixels together appear as a single white pixel. When all are dark, the three colored subpixels together appear as a single black pixel. Other combinations of lit and dark subpixels appear as single pixels of other colors. Types of Pixel Defects Pixel and subpixel defects appear on the screen in different ways. There are two categories of pixel defects and several types of subpixel defects within each category. Bright Dot Defects Bright dot defects appear as pixels or subpixels that are always lit or "on". These are the types of bright dot defects:

BLACK DOT DEFECTS One lit red, green or blue subpixel MODEL 1 dark subpixel 2 adjacent dark subpixels 3 adjacent dark subpixels Distance between two black dot defects* Two adjacent lit subpixels: - Red + Blue = Purple - Red + Green = Yellow - Green + Blue = Cyan (Light Blue) Black dot defects within 20 mm circle* Total black dot defects of all types

ACCEPTABLE LEVEL 170B4&S4 4 or fewer 2 or fewer 1 or fewer 15 mm or more 4 or fewer

TOTAL DOT DEFECTS MODEL

ACCEPTABLE LEVEL 170B4&S4

Total bright or black dot defects of all types 4 or fewer Three adjacent lit subpixels (one white pixel)

Note: 1 or 2 adjacent subpixel defects = 1 dot defect

Warning and Notes
Notes 1. The direct voltages and waveforms are average voltages. They have been measured using the Service test software and under the following conditions : - Mode : 640 * 480 (31.5kHz / 60Hz) - Signal pattern : grey scale - Adjust brightness and contrast control for the mechanical mid-position (click position) 2. The picture tube panel has printed spark gaps. Each spark gap is connected between an electrode of the picture tube and the Aquadag coating. 3. The semiconductors indicated in the circuit diagram(s) and in the parts lists are completely interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.

Warnings 1. Safety regulations require that the unit should be returned in its original condition and that components identical to the original components are used. The safety components are indicated by the symbol . 2. In order to prevent damage to ICs and transistors, all high-voltage flash-overs must be avoided. In order to prevent damage to the picture tube, the method shown in Fig. 1 should be used to discharge the picture tube. Use a high-voltage probe and a multimeter (position DC-V). Discharge until the meter reading is 0 V (after approximately 30 seconds). 3. ESD All ICs and many other semiconductors are sensitive to electrostatic discharges (ESD). Careless handling during repair can drastically shorten their life. Make sure that during repair you are connected by a pulse band with resistance to the same potential as the ground of the unit. Keep components and tools also at this same potential. 4. When repairing a unit, always connect it to the AC Power voltage via an isolating transformer.

V

5. Be careful when taking measurements in the high-voltage section and on the picture tube panel. 6. It is recommended that saferty goggles be worn when replacing the picture tube. 7. When making adjustments,use plastic rather than metal tools. This will prevent any short-circuit or the danger of a circuit becoming unstable. 8. Never replace modules or other components while the unit is switched on. 9. Together with the defleciton unit, the picture tube is used as an integrated unit. Adjustment of this unit during repair is not recommended. 10. After repair, the wiring should be fastened in place with the cable clamps. 11. All units that are returned for service or repair must pass the original manufactures safety tests.

CLOCK & PHASE Adjustments
The monitor has build-in a auto adjustment hotkey on the front panel, you may obtained a optimal video display by simply press the AUTO button and save the settings. CLOCK, PHASE, Vertical position, and Horizontal position are adjusted automatically. Due to the different quality of video signal generated from graphics cards. By press AUTO button for CLOCK and PHASE adjustment automatically. Sometimes, the deviation of video signal which generated from graphics cards is out of control, then it is necessary to adjust CLOCK and PHASE functions for the optimal video display of LCD monitor by manual. Following steps will guide you to make correct adjustment of CLOCK and PHASE. However, CLOCK and PHASE functions are only available while analog video signal is supplied. Operating unit under digital signal state, the video clock information can be obtained from graphics cards directly. Therefor, it is unnecessary to adjust these functions.
