Burn-in/Ghost image
Always
activate a moving screen saver program when you leave your monitor unattended.
Always activate a periodic screen refresh application if your monitor will
display unchanging static content. Uninterrupted display of still or static
images over an extended period may cause “burn in”, also known as
“after-imaging” or “ghost imaging”, on your screen. "Burn-in", "after-imaging",
or "ghost imaging" is a well-known phenomenon in LCD panel
technology. In most cases, the “burned in” or “after-imaging” or “ghost
imaging” will disappear gradually
over a period of time after the power has been switched off.
over a period of time after the power has been switched off.
Failure
to activate a screen saver, or a periodic screen refresh application may result
in severe ” burn-in” or “after-image” or “ghost image” symptoms will not
disappear and cannot be repaired. The damage mentioned above is not covered
under your warranty
If
you have VESA DPM compliance display card or software installed in your PC, the
monitor can automatically reduce its power consumption when not in use. If an
input from a keyboard, mouse or other input device is detected, the monitor
will 'wake up' automatically. The following table shows the power consumption
and signaling of this automatic power saving feature:
Pixel Defect
Philips
strives to deliver the highest quality products. Philips use some of the industry's most
advanced manufacturing processes and practice stringent quality control.
However, pixel or sub pixel defects on the TFT Monitor 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 Monitor
panel must exceed these acceptable levels. For example, no more than 0.0004% of
the sub pixels on a 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.
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.

Types of Pixel Defects
Pixel and sub pixel defects appear on the screen in different ways. There are two categories of pixel 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'. That is, a bright dot is a sub-pixel that stands out on the screen when the monitor displays a dark pattern. There are the types of bright dot defects.
Bright dot defects appear as pixels or sub pixels that are always lit or 'on'. That is, a bright dot is a sub-pixel that stands out on the screen when the monitor displays a dark pattern. There are the types of bright dot defects.
A
red or blue bright dot must be more than 50 percent brighter than neighboring
dots while a green bright dot is 30 percent brighter than neighboring dots.
Black Dot Defects
Black dot defects appear as pixels or sub pixels that are always dark or 'off'. That is, a dark dot is a sub-pixel that stands out on the screen when the monitor displays a light pattern. These are the types of black dot defects.
Proximity of Pixel DefectsBlack Dot Defects
Black dot defects appear as pixels or sub pixels that are always dark or 'off'. That is, a dark dot is a sub-pixel that stands out on the screen when the monitor displays a light pattern. These are the types of black dot 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.
Failure Mode Of Panel

General
DDC Data Re-programming
In case the main EEPROM with Software DDC which store all factory settings were replaced because a defect repaired monitor’ the serial numbers have to be re-programmed.
It is advised to re- soldered the main EEPROM with Software DDC 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 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.

Check
the SN
1. Connect the VGA or DVI source and power on monitor.
2. Press the “MENU” button to enter the user menu. We can check the 14 digital SN on the bottom right of the menu.

If
this SN number is the same as what we had written by EDID tool, the EDID and SN
writing is completed finally
When
you can’t burn in the EDID and SN, try the following ways.
1. AC on the monitor and turn on it.
2. Cut off the 5 pin of VGA cable terminal connected to monitor

3.
Take apart the monitor and connect the 7pin of EEPROM to GND to disable write
protection.
Can’t
write error, try below few ways to cure can’t write errors!
1) AC on the monitor and turn on it.(Restart the monitor)
2) Take apart the monitor and connect the 7pin of EEPROM to GND to disable write protection then write EDID one by one.
3) Set the Burn in on to try again
