Response time <=16ms (typ.) sRGB sRGB is a standard for ensuring correct exchange of colors between different devices (e.g. Digital cameras, monitors, printers, scanners, etc.) Using a standard unified color space, sRGB will help represent pictures taken by an sRGB compatible device correctly on your sRGB enabled Philips monitors. In that way, the colors are calibrated and you can rely on the correctness of the colors shown on your screen. Important with the use of sRGB is that the brightness and contrast of your monitor is fixed to a predefined setting as well as the color gamut. Therefore it is important to select the sRGB setting in the monitor's OSD. To do so, at PC mode, open the OSD by pressing the MENU button of your monitor. Use the down button to go to COLOR SETTINGS and press MENU again. Then move the down button to go to NORMAL COLOR and press MENU again. For more information on sRGB, please visit: www.srgb.com * This data is subject to change without notice. Resolution & Preset Modes Recommended : 1280 x 768 at 60Hz 10 factory preset modes:

Warning Message
Self-Test Feature Check (STFC) Your the LCD Monitor TV when used as a computer display through DVI and/or VGA connection provides a self-test feature that allows you to check whether your the LCD Monitor TV is functioning properly. If your the LCD Monitor TV and computer are properly connected but the LCD Monitor TV screen remains dark, run the LCD Monitor TV self-test by performing the following steps: 1. Turn off both your computer and the LCD Monitor TV. 2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital(white connector) and the Analog(blue connector) cables from the back of computer. 3. Turn on the LCD Monitor TV. The floating 'Philips - self-test Feature Check' dialog box should appear on-screen (against a black background) if the LCD Monitor TV cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.
A warning message may appear on the screen indicating the LCD Monitor TV current status.
When user sees this warning message, it means that the LCD Monitor TV is in adjustment process.
A warning message may appear on the screen indicating that the LCD Monitor TV is out of sync range. See Specifications for the Horizontal and Vertical frequency ranges addressable by this the LCD Monitor TV. Recommended mo de is 1280x 768 @ 60Hz.
This box also appears during normal system operation if the video cable becomes disconnected or damaged. 4. Turn off your the LCD Monitor TV and reconnect the video cable; then turn on both your computer and the LCD Monitor TV. If your the LCD Monitor TV screen remains blank after you use the previous procedure, check your video controller and computer system; your LCD Monitor TV is functioning properly.
This message means that there is no video input signal.
The LCD Monitor TV is in a power saving mode (in PC mode).

Troubleshooting
TV and Audio Problems COMMON SYMPTOMS Poor TV signal reception WHAT YOU EXPERIENCE POSSIBLE SOLUTIONS
Abnormal picture seen from the screen The proximity of mountains or high buildings may be responsible for ghost pictures, echoing or shadows. In this case, try manually adjusting your pictures: see 'fine tuning' or adjust the direction of the outside aerial. For Asia users in non-NTSC area: Does your antenna enable you to receive broadcasts in this frequency range UHF or VHF band)? In the event of difficult reception (snowy pictures) switch the NR on the PICTURE menu to ON. No picture when TV input was selected Have you connected the aerial socket properly? Have you chosen the right system? Poorly connected SCART Cables or aerial sockets are often the cause of picture or sound problems (sometimes the connectors can become half disconnected if the LCD TV set is moved or turned). Check all connections. Ensure that the audio cables are firmly connected to both the audio input connectors on your LCD TV and audio output connectors on your PC or Video player. If on certain TV channels you receive a picture but no sound, this means that you do not have the correct TV system. Modify the SYSTEM setting.
No TV picture

Definition of Pixel Defects
3. 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.
0. General
This section explains the different types of pixel defects and defines acceptable defect levels of 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.
1. Definition of 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 from 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.

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. 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).

1. Configuration and procedure
There are two ICs contained serial number on the circuit board, Analog Flash ROM IC (7301), and main EEPROM (7302) which storage all factory settings. Following descriptions are the connection and procedure for Analog Flash ROM IC , the main EEPROM can be re-programmed along with Analog IC by enable factory memory data write function on the DDC program (EDID301.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 (EDID301.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 video cable of monitor as Fig. 1 Step 3: Run the EDID301.EXE program until the main menu appears. This is for initialize alignment box.
