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:

TV and Audio Problems
COMMON SYMPTOMS
Poor TV signal reception
Troubleshooting
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 TV picture

Cannot adjust the LCD TV with the buttons on the front panel
No picture when TV input was selected
No sound output when a program with sound was playing
WHAT YOU EXPERIENCE
No signal indicator is displayed.
Picture not crisp and some color Distortion
See video but no audio
WHAT YOU EXPERIENCE
No response from LCD TV when remote is pressed
WHAT YOU SEE
Image is centered on screen, but does not fill entire viewing area
OSD does not appear on the screen
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.
POSSIBLE SOLUTIONS
Check Video Input Selection Composite: Yellow colored RCAjack S-Video: Typically a round 4 pin jack Component: Typically 3 RCA jacks of Green, Red and Blue.
Check DVD connection Composite gives good picture S-Video gives better picture Component gives best picture
Check if TV volume is turn off of muted Connect the audio cable securely Audio cable is connected incorrectly Verify that the audio source is selected correctly in the OSD
POSSIBLE SOLUTIONS
Point the remote control directly at the remote sensor on the LCD TV Replace both batteries with new onesl
POSSIBLE SOLUTIONS
Perform LCD TV reset on "All Settings"
Turn the LCD TV off and unplug the power cord and then plug back and power on

Definition of Pixel Defects
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.
