SAFETY AND TROUBLESHOOTING INFORMATION
Safety precautions and maintenance
WARNING: Use of controls, adjustments or procedures other than those specified in this
documentation may result in exposure to shock, electrical hazards and/or mechanical
hazards.
Read and follow these instructions when connecting and using your display:
Operation:
• Keep the display out of direct sunlight and away from stoves or any other heat sources.
• Remove any object that could fall into ventilation holes or prevent proper cooling of the display’s electronics.
• Do not block the ventilation holes on the cabinet.
• When positioning the display, make sure the power plug and outlet are easily accessible.
• When turning off the display by detaching the power cord, wait 6 seconds before re-attaching the power cord for
normal operation.
• Ensure the use of an approved power cord provided by Philips at all times. If your power cord is missing, please contact
your local service center.
• Do not subject the display to severe vibration or high impact conditions during operation.
• Do not knock or drop the display during operation or transportation.
Maintenance:
• To protect your display from possible damage, do not put excessive pressure on the LCD panel. When moving your
display, grasp the frame to lift; do not lift by placing your hand or fingers on the LCD panel.
• Unplug the display if you are not going to use it for an extensive period of time.
• Unplug the display if you need to clean it with a slightly damp cloth. The screen may be wiped with a dry cloth when the
power is off. However, never use organic solvent, such as, alcohol, or ammonia-based liquids to clean your display.
• To avoid the risk of shock or permanent damage to the set, do not expose the display to dust, rain, water or an
excessively moist environment.
• If your display becomes wet, wipe it with dry cloth as soon as possible.
• If a foreign substance or water gets in your display, turn the power off immediately and disconnect the power cord.
Then remove the foreign substance or water, and send the unit to the maintenance center.
• Do not store or use the display in locations exposed to heat, direct sunlight or extreme cold.
• In order to maintain the best performance of your display and ensure a longer lifetime, we strongly recommend using
the unit in a location that falls within the following temperature and humidity ranges.
- Temperature: 0 ~ 40 C 32-104 F
- Humidity: 20-80% RH
IMPORTANT: Always activate a moving screen saver program when you leave your display unattended. Always activate a
periodic screen refresh application if the unit 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.
This 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.
WARNING: Severe "burn-in" or "after-image" or "ghost image" symptoms will not disappear and cannot be repaired.
This is also not covered under the terms of your warranty.
User Manual BDL4230ET
Service:
• The casing cover should be opened only by qualified service personnel.
• If there is any need for repair or integration, please contact your local service center.
• Do not leave your display under direct sunlight.
If your display does not operate normally, having followed the instructions set out in this document, please
contact a technician or your local service center.
Read and follow these instructions when connecting and using your display:
• Unplug the display if you are not going to use it for an extensive period of time.
• Unplug the display if you need to clean it with a slightly damp cloth. The screen may be wiped
with a dry cloth when the power is off. However, never use alcohol, solvents or ammonia-based
liquids.
• Consult a service technician if the display does not operate normally after having followed the
instructions in this manual.
• The casing cover should be opened only by qualified service personnel.
• Keep the display out of direct sunlight and away from stoves or any other heat sources.
• Remove any object that could fall into the vents or prevent proper cooling of the display’s
electronics.
• Do not block the ventilation holes on the cabinet.
• Keep the display dry. To avoid electric shock, do not expose it to rain or excessive moisture.
• When turning off the display by detaching the power cable or DC power cord, wait for 6
seconds before re-attaching the power cable or DC power cord for normal operation.
• To avoid the risk of shock or permanent damage to the set, do not expose the display to rain or
excessive moisture.
• When positioning the display, make sure the power plug and outlet are easily accessible.
• IMPORTANT: Always activate a screen saver program during your application. If a still image in
high contrast remains on the screen for an extended period of time, it may leave an “afterimage” or “ghost image” on the front of the screen. This is a well-known phenomenon that is
caused by the shortcomings inherent in the LCD technology. In most cases the afterimage will
disappear gradually over a period of time after the power has been switched off. Be aware that
the after-image symptoms cannot be repaired and are not covered under warranty.

INFORMATION FOR UK ONLY
WARNING - THIS APPLIANCE MUST BE EARTHED.
Important:
This apparatus is supplied with an approved moulded 13A plug. To change a fuse in this
type of plug proceed as follows:
1. Remove fuse cover and fuse.
2. Fit new fuse which should be a BS 1362 5A, A.S.T.A. or BSI approved type.
3. Refit the fuse cover.
If the fitted plug is not suitable for your socket outlets, it should be cut off and an
appropriate 3-pin plug fitted in its place.
If the mains plug contains a fuse, this should have a value of 5A. If a plug without a fuse
is used, the fuse at the distribution board should not be greater than 5A.
Note: Any severed plug must be destroyed to avoid a possible shock hazard should it
be inserted into a 13A socket elsewhere.
How to connect a plug
The wires in the mains lead are colored in accordance with the following code:
BLUE - “NEUTRAL” (“N”)
BROWN - “LIVE” (“L”)
GREEN & YELLOW - “EARTH” (‘E”)
1. The GREEN AND YELLOW wire must be connected to the terminal in the plug
which is marked with the letter “E” or by the Earth symbol or
coloured GREEN
or GREEN AND YELLOW.
2. The BLUE wire must be connected to the terminal which is marked with the letter
“N” or coloured BLACK.
3. The BROWN wire must be connected to the terminal which marked with the letter
“L” or coloured RED.
Before replacing the plug cover, make certain that the cord grip is clamped over the
sheath of the lead - not simply over the three wires.

Notes:
• Seven scheduling options are available so that you can choose between different video input modes for different
schedules during the week. For example, VGA input on a Monday, HDMI on Tuesday to Friday, S-VIDEO for
weekends.
• If you do not want to use a power on time, select "--" for the power on hour slot, and "00" for the minute slot. The
display will only turn off at the time you set.
• If you do not want to use a power off time, select "--" for the power off hour slot, and "00" for the minute slot. The
display will only turn on at the time you set.
• If no input source is selected, the default input source (VIDEO) will be used.
• If EVERY DAY is selected, the display will turn on everyday regardless of other day settings (e.g MON, TUE, WED...,
etc.).
• Should schedule periods overlap, the power on time has priority over power off time. For example, if schedule item
#1 sets the display to power on at 10:00 AM and off at 5:00 PM, and schedule item #2 sets the display to power
on at 4:00 PM and off at 9:00 PM on the same day, then the display will power on at 10:00 AM and off at 9:00
PM.
• If there are multiple schedule items programmed for the same time period, then the highest numbered schedule item
has priority. For example, if schedule items #1 and #2 both set the display to power on at 7:00 AM and off at 5:00
PM, then only schedule item # 1 will take effect.

PIXEL DEFECT POLICY
We strive to deliver the highest quality products and use some of the industry's most advanced manufacturing processes
whilst practicing 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 LCD display 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 BDL4230ET LCD
screen. In order to qualify for repair under warranty, the number of pixel defects must exceed a certain level as shown 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.
7.1. 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.

7.2. 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 is defined as one "dot". The number of defective sub-pixels is 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.
One dot = One Pixel; consists of three sub-pixels of Red; Green and Blue
RETURN TO THE CONTENTS
User Manual BDL4230ET
7.3. 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)
7.4. 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
Two adjacent dark dots = 1 pair of
dark dots
Two dark dots, specifications define
the minimum distance between dark
dots
7.5. PROXIMITY OF PIXEL DEFECTS
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
7.6. PIXEL DEFECT TOLERANCES
In order to qualify for repair due to pixel defects during the warranty period, a PDP/TFT panel in a Philips LCD display
must have pixel or sub-pixel defects exceeding the tolerances listed in the following table.
BRIGHT DOT EFFECT
ACCEPTABLE LEVEL
MODEL

CLEANING AND TROUBLESHOOTING
8.1.
CLEANING
Caution When Using the Display
• Do not place your hands, face or objects close to the ventilation holes of the
display. The top of the display is usually very hot due to the high temperature of
the air being expelled through the ventilation holes. Burns or personal injuries
may occur if any body parts are brought too close. Placing any object near the
top of the display could also result in heat related damage to the object as well
as the display itself.
• Be sure to disconnect all cables before moving the display. Moving the display
with its cables attached may damage the cables and thus cause fire or electric
shock.
• Disconnect the power plug from the wall outlet as a safety precaution before
carrying out any type of cleaning or maintenance procedure.
Front Panel Cleaning Instructions
• The front of the display has been specially treated. Wipe the surface gently
using only a cleaning cloth or a soft, lint-free cloth.
• If the surface becomes dirty, soak a soft, lint-free cloth in a mild detergent
solution. Wring the cloth to remove excess liquid. Wipe the surface of the
display to remove dirt. Then use a dry cloth of the same type to dry.
• Do not scratch or hit the surface of the panel with fingers or hard objects of
any kind.
• Do not use volatile substances such as sprays, solvents and thinners.
Cabinet Cleaning Instructions
• If the cabinet becomes dirty, wipe with a soft, dry cloth.
• If the cabinet is extremely dirty, soak a lint-free cloth in a mild detergent
solution. Wring the cloth to remove as much moisture as possible. Wipe the
cabinet. Use another dry cloth to wipe over until the surface is dry.
• Do not allow any water or detergent to come into contact with the surface of
the display. If water or moisture gets inside the unit, operating problems, or
electrical and shock hazards may result.
• Do not scratch or hit the cabinet with fingers or hard objects of any kind.
• Do not use volatile substances such as sprays, solvents and thinners on the
cabinet.
• Do not place anything made from rubber or PVC near the cabinet for any
extended periods of time.
