Color is abnormal The signal cable is not connected properly Make sure that the signal cable is attached firmly to
the back of the monitor.
Picture is distorted with abnormal
patterns
1. The signal cable is not connected properly.
2. The input signal is beyond the capabilities of
the monitor.
1. Make sure that the signal cable is attached firmly.
2. Check the video signal source to see if it is
beyond the range of the monitor. Please verify its
specifications with this monitor’s specification
section.
Display image doesn’t fill up the
full size of the screen The zoom mode is not correctly set.
Use the ZOOM MODE or CUSTOM ZOOM function
in the SCREEN menu to fine tune display geometry
and time frequency parameter.
Can hear sound, but no picture Improperly connected source signal cable. Make sure that both video inputs and sound inputs
are correctly connected.
Can see picture but no sound is
heard
1. Improperly connected source signal cable.
2. Volume is turned all the way down.
3. MUTE is turned on.
4. No external speaker connected
1. Make sure that both video inputs and sound
inputs are correctly connected.
2. Use VOL UP/VOL DOWN button to hear sound.
3. Switch MUTE off by using the MUTE button.
4. Connect external speakers and adjust the
volume to a suitable level.
Some picture elements do not
light up Some pixels of the display may not turn on.

the monitor after the monitor is
powered off. (Examples of still
pictures include logos, video
games, computer images, and
images displayed in 4:3 normal
mode)
A still picture is displayed for an over extended
period of time
Do not allow a still image to be displayed for an
extended period of time as this can cause a
permanent after-image to remain on the monitor.

Description of the On Screen Displayʳ
What is the On-Screen Display?ʳ
On-Screen Display (OSD) is a feature in all Philips LCD monitors. It allows an end user to adjust screen performance or
select functions of the monitors directly through an on-screen instruction window. A user friendly on screen display

Philips Pixel Defect Policyʳ
Philips' Flat Panel Displays Pixel Defect Policyʳ
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 PDP / TFT panels
used in Plasma- & LCD- displays are sometimes unavoidable. No
manufacturer can guarantee that all panels will be free from pixel defects,
but Philips guarantees that any Plasma- & LCD- displays with an
unacceptable number of defects will be repaired during the warranty period
in line with your local guarantee conditions. This notice explains the different
types of pixel defects and defines the acceptable defect level for the
BDL4230E LCD screen. In order to qualify for repair under warranty, the
number of pixel defects must exceed a certain level which is given in the
reference table. If the LCD screen is within specification a warranty
exchange / claim back will be refused. Additionally, because some types or
combinations of pixel defects are more noticeable than others, Philips sets
even higher quality standards for those.
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 + Dot Definition
Pixel and sub-pixel defects appear on the screen in different ways. There are
three categories of pixel defects and several types of sub-pixel defects within
each category. Dot definition = What is a defective "Dot"? : One or more
defective, adjacent sub-pixel are defined as one "dot". The no. of defective
sub-pixels are not relevant to define a defective dot. This means that a
defective dot can consist of one, two or three defective sub-pixels which can
be dark or lit.
Bright Dot Defects
Bright dot defects appear as pixels or sub-pixels that are always lit or "on".
These are the examples of bright dot defects:
One lit red, green or
blue sub-pixel
Two adjacent lit
sub-pixels: - Red +
Blue = Purple - Red +
Green = Yellow -
Green + Blue = Cyan
(Light Blue)
Three adjacent lit
sub-pixels (one white
dot)
Dark Dot Defects
Black dot defects appear as pixels or sub-pixels that are always dark or "off".
These are the examples of black dot defects
One dark dot l Two adjacent dark
dots = 1 pair of dark
dots Green = Yellow -
Green + Blue = Cyan
(Light Blue)
Two dark dots,
specifications defines
the minimum distance
between dark dots
Proximity of Pixel Defects ʳ
Because pixel and sub-pixels defects of the same type that are nearby one
another may be more noticeable, Philips also specifies tolerances for the
proximity of pixel defects. In the table below you can find specifications
about: • Allowed amount of adjacent dark dots = (adjacent dark dots =1 pair
of dark dots) • Minimum distance between dark dots • Total no. of all
defective dots
Pixel Defect Tolerances
In order to qualify for repair due to pixel defects during the warranty period, a
PDP / TFT panel in a Philips Plasma / LCD- display must have pixel or
sub-pixel defects exceeding the tolerances listed in the following table.
