1. Safety Precautions

I. Parts with the exception of MODULE

1. Safety Precautions

(1) When moving or laying down a PDP Set, at least two people must work together. Avoid

any impact towards the PDP Set.

(2) Do not leave a broken PDP Set on for a long time. To prevent any further damages, after

checking the condition of the broken Set, make sure to turn the power (AC) off.

(3) When opening the BACK COVER, you must turn off power (AC) to prevent any electric

shock. When PDP is operating, high voltage and high current inside the Set can cause
electric shocks.

(4) When loosening screws, check the position and type of the screw. Sort out the screws and

store them separately for reassembling. Because screws holding PCBs are working as
electric circuit GROUNDING, make sure to check if any screw is missing when
assembling/reassembling. Do not leave any screws inside the set.

(5) If you open the BACK COVER, you will see a

Panel Gas Exhaust Tube (Picture. 1-1) inside
the bracket. If this part is damaged, the entire
PDP PANEL must be replaced. Therefore,
when working with the set, be careful not to
damage this part.

Picture 1-1. Panel Gas Exhaust Tube

(6) A PDP Set contains different kinds of

connector cables. When connecting or disconnecting cables, check the direction and
position of the cable beforehand.

(7) Connect/disconnect the connectors slowly with care especially FFC (film) cables and FPC

cables. Do not connect or disconnect connectors instantaneously with force, and handle
them carefully for reassembling.

(8) Connectors are designed so that if the number of pins or the direction does not match,

connectors will not fit. When having problem in plugging the connectors, check their kind,
position, and direction.

Before starting Trouble Shooting

z Trouble diagnosing and repairing of set mean find out which PCBs or blocks are

not working and replace them with new PCBs. Repairing the broken PCBs are

not necessary. Keep the broken PCBs and return them to service center or

R&D center.

z This Trouble Shooting list only contains representative and simple PCB trouble

diagnosis and Module Exchange method. Therefore, if you find sets that are

difficult to diagnose or to repair, contact R&D center.

z Basic Trouble Diagnosis procedure

1) Check problem Symptoms

2) Open Back Cover

3) Trouble Diagnosis & Replace broken PCB

4) Adjust new PCB module

5) HEATRUN for at least 30 minutes, inputting Full White test pattern

6) Full Function test

7) Repair Complete

z Required Equipment for trouble diagnosis

1) Digital Multimeter (User Mode : measure DC Voltage, measure Diode

Voltage, Short-open test)

2) Screwdriver (or electric screwdriver), Plastic adjusting tool

3) Oscilloscope (for detailed examination only)

z Before replacing PCBs, you MUST turn the AC switch “OFF”.
z After replacing High Voltage Board (Power PCB, Y-SUS, Z-SUS, Data B/D,

Scan B/D), and Main & Sub PCB, extra adjustment might be needed. (Refer to

Power Adjustment)

z Dust or extraneous materials may cause bad connections. Therefore, try to

apply soft brush, air fresher, or breath to clean the dust or extraneous materials.

z While assembling the set in factory, it could have bad connection. Try to

reassemble the necessary connectors and also check the state of the

connectors.

z After the set is repaired, leave Back Cover open for followings. Run HEAT

RUN for at least 30 minutes by displaying Full White test pattern of Service
Mode (Refer to Service Manual I. ‘Service Mode’ part). Check the screen

conditions and basic functions (remote control operation etc.)

z

After Back Cover is closed, redo HEAT RUN for at least one hour with Full

Trouble Shooting

-45-

White input using Test Pattern of Service Mode. Check the screen conditions

and basic functions.

z Caution 1 !!

z Caution 2 !!

Definition

When disconnecting / connecting connectors, you MUST turn “OFF” the AC

power and check the direction and position of the connectors before

working.

Whenever you reassemble connectors connecting High Voltage Board and

POWER PCB (CN805, CN806), remaining voltage still exists in the POWER

PCB could cause electric shock and damage the set. Therefore always

reassemble the connectors several minutes after AC power is off. To be

more careful, using a Multimeter you should check to see if Vs is less than

10V and then connect connectors.

z Red LED – Stand by state (ready for operating)
z Green LED – The set is turned on and operating
z Shut Down – While green LED, power PCB does not make any operating sound

or noise (i.e. Power relay does not operate normally)

z Weak Discharge – The screen looks like BLACK, but there are little discharged

cells on the screen

z Abnormal Discharge – Shows unexpected discharged cells on the image
z No Signal – OSD is working but no images are displaying
z No Raster – Not even OSD is displaying

(4) If a foreign substance (such as water, metal, or liquid) gets

inside the product, immediately turn off the power.
Continuing to use the product, it is may cause fire or
electric shock.

(5) If the product emits smoke, and abnormal smell, or makes

an abnormal sound, immediately turn off the power.
Continuing to use the product, it may cause fire or electric
shock.

(6) Do not disconnect or connect the connector while power to

the product is on. It takes some time for the voltage to drop
to a sufficiently low level after the power has been turned
off.
Confirm that the voltage has dropped to a safe level before
disconnecting or connecting the connector.

(7) Do not pull out or insert the power cable from/to an outlet

with wet hands. It may cause electric shock.

(8) Do not damage or modify the power cable. It may cause

fire or electric shock.

(9) If the power cable is damaged, or if the connector is loose,

do not use the product: otherwise, this can lead to fire or
electric shock.

(10) If the power connector or the connector of the power

cable becomes dirty or dusty, wipe it with a dry cloth.
Otherwise, this can lead to fire.

(11) PDP Module uses a high voltage (Max.450V dc). Keep

the cautions concerning electric shock and do not touch
the Device circuitry when handling the PDP Unit. And
because the capacitor of the Device circuitry may remain
charged at the moment of Power OFF, standing by for 1
minute is required in order to touch the Device circuitry.

2) CAUTIONS

(1) Do not place this product in a location that is subject to

heavy vibration, or on an unstable surface such as an
inclined surface. The product may fall off or fall over,
causing injuries.

(2) Before disconnecting cable from the product, be sure to

turn off the power. Be sure to hold the connector when
disconnecting cables. Pulling a cable with excessive force
may cause the core of the cable to be exposed or break
the cable, and this can lead to fire or electric shock.

(3) This product should be moved by two or more persons. If

one person attempts to carry this product alone, he/she
may be injured.

(4) This product contains glass. The glass may break, causing

injuries, if shock, vibration, heat, or distortion is applied to
the product.

(5) The temperature of the glass of the display may rise to

80°C or more depending on the conditions of use.
If you touch the glass inadvertently, you may be burned.

(6) If glass surface of the display breaks or is scratched, do

not touch the broken pieces or the scratches with bare
hands. You may be injured.

(7) PDP Module requires to be handled with care not to be

touched with metal or hard materials, and must not be
stressed by heat or mechanical impact.

(8) There are some exposed components on the rear panel of

this product. Touching these components may cause an
electric shock.

(9) When moving the product, be sure to turn off the power

and disconnect all the cables. While moving the product,
watch your step. The product may be dropped or all,
leading to injuries of electric shock.

Ⅰ. Safety Precautions/Technical Feature

(10) In order to protect static electricity due to C-MOS circuitry of

the Drive part, wear a wrist band to protect static electricity
when handling.

(11) If cleaning the Panel, wipe it with a soft cloth moistened with

water or a neutral detergent and squeezed, being careful not
to touch the connector part of the Panel. And don’t use
chemical materials like thinner or benzene.

(12) If this product is used as a display board to display a static

image, “image sticking” occurs. This means that the luminance
of areas of the display that remain lit for a long time drops
compared with luminance of areas that are lit for a shorter
time, causing uneven luminance across the display.
The degree to which this occurs is in proportion to the
luminance at which the display is used. To prevent this
phenomenon, therefore, avoid static images as much as
possible and design your system so that it is used at a low
luminance, by reducing signal level difference between bright
area and less bright area through signal processing.

(13) Because PDP Module emits heat from the Glass Panel part

and the Drive circuitry, the environmental temperature must
not be over 40°C.
The temperature of the Glass Panel part is especially high
owing to heat from internal Drive circuitry. And because the
PDP Module is driven by high voltage, it must avoid
conductive materials.

(14) If inserting components or circuit board in order to repair, be

sure to fix a lead line to the connector before soldering.

(15) If inserting high-power resistor(metal-oxide film resistor or

metal film resistor) in order to repair, insert it as 10mm away
as from a board.

(16) During repairs, high voltage or high temperature components

must be put away from a lead line.

(17) This is a Cold Chassis but you had better use a cold

transformer for safety during repairs. If repairing electricity
source part, you must use the cold transformer.

(18) Do not place an object on the glass surface of the display.

The glass may break or be scratched.

(19) This product may be damaged if it is subject to excessive

stresses (such as excessive voltage, current, or temperature).
The absolute maximum ratings specify the limits of these
stresses.

(20) The recommended operating conditions are conditions in

which the normal operation of this product is guaranteed. All
the rated values of the electrical specifications are guaranteed
within these conditions.
Always use the product within the range of the recommended
operating conditions. Otherwise, the reliability of the product
may be degraded.

(21) This product has a glass display surface. Design your

system so that excessive shock and load are not applied to
the glass. Exercise care that the vent at the corner of the glass
panel is not damaged.
If the glass panel or vent is damaged, the product is
inoperable.

(22) Do not cover or wrap the product with a cloth or other

covering while power is supplied to the product.

(23) Before turning on power to the product, check the wiring of

the product and confirm that the supply voltage is within the
rated voltage range. If the wiring is wrong or if a voltage
outside the rated range is applied, the product may
malfunction or be damaged.

(24) Do not store this product in a location where temperature

and humidity are high. This may cause the product to
malfunction. Because this product uses a discharge
phenomenon, it may take time to light (operation may be
delayed) when the product is used after it has been stored for
a long time. In this case, it is recommended to light all cells for
about 2 hours (aging).

(25) This product is made from various materials such as glass,

metal, and plastic. When discarding it, be sure to contact a
professional waste disposal operator.

(26) If faults occur due to arbitrary modification or disassembly,

LG Electronics is not responsible for function, quality or other
items.

(27) Use of the product with a combination of parameters,

conditions, or logic not specified in the specifications of this
product is not guaranteed. If intending to use the product in
such a way, be sure to consult LGE in advance.

(28) Within the warranty period, general faults that occur due to

defects in components such as ICs will be rectified by LGE
without charge. However, IMAGE STICKING due to
misapplying the above (12) provision is not included in the
