2.3 Servicing Precautions
A colour TFT LCD Module can easily be damaged by both
electrical and mechanical stresses. Users therefore, are
requested to follow the “Servicing precautions of colour TFT
LCD Module” on the following.
2.3.1 System Assembler
•Follow the power sequence: An abnormal power
sequence may cause critical malfunction or electrical
damage.
•Prevent physical stress.
•Prevent overheat:
– High temperatures on the surface of the screen may
cause poor quality. Please use the LCD Module on the
specified temperatures.
– Low temperatures (under 10 deg. C) makes the LCD
Module respond slowly, make the Backlight worse
operated, and will shorten very much the lifetime
accordingly.
•Keep LCD Module dust-free: The LCD Module is
sensitive against dust; it can cause visual or functional
problems.

Directions for Use
EN 4 LCD AUO 2k83.
•Do not touch TCP area: Do not touch TCP area at any
case. It can cause Driver IC cracks, film cracks, etc. The
TCP is the weakest point of the LCD Module.
•Do not pull Backlight wire: Please do not pull the
Backlight wire, as it can cause the wire to become
disconnected or damaged.
•Check the connections of the Inverter & Backlight
connectors: Incomplete connection can cause burnt in
Backlight connectors or damage the inverter.
•Handle with care:
– Please do not drop, bend, or hit the LCD Module.
– Physical stress can cause defects as broken panels.
•Keep mounting screw length and motor driver’s
torque: Strong motor driver’s torque can make a
mechanical defect on LCD Module. Please keep within the
specifications.
•Do not operate for a long time under the same pattern:
Operating the LCD Module for a long time with the same
video pattern can cause image persistence and can
eventually damage it.
•Defective panels must also be handled with care:
– To prevent making other defects, please handle the
defective LCD Module as a good one.
– Defective LCD Modules must be repaired.
•Do not stack LCD Modules: The LCD Module consists of
fragile components such as TCPs or Glasses. Stacking the
LCD Modules can cause undesired defects.
•Do not provide strong pressure at connecting: Strong
pressure can transfer the force to the TCP, which is the
weakest part of the LCD Module. It eventually can make
the TCP crack or lead to other unexpected defects.
•Let the Backlight Wire at the backside of the LCD
Module: If let the Backlight wire in front of the LCD Module,
the Backlight connector can hurt the surface of the
polariser.
•Never (dis)connect at power “ON”: The LCD Module
consists of CMOS components, which are known as weak
components against EOS. It can damage the product.
•Electro-static discharge can make damage:
– Semi-assembled product should be handled with wrist
strap.
– Earth human body when handle the LCD Module.
– Please do not touch the interface connector pin.
2.3.2 System Assembler/End User
•Keep clean the surface:
– Please wear rubber gloves when you touch the surface
of the LCD Module screen.
– Please use soft and anti-static material with n-Hexane
as cleaner.
•Be careful not to make polariser scratch:
– Surface of polariser is soft, so it’s easily scratched.
– Please do not touch, press or rub on polariser surface
with materials over HB hardness.
•Be careful with swift temperature and humidity
changes: Swift temperature and or humidity change can
make dew condensation or ice, which can cause non-
conformance such as malfunctioning.
•Keep out of water:
– Water on in the LCD Module can cause electrical short
or corrosion.
– Please wipe out or dry water carefully.
•Keep the LCD Module free from corrosive gasses:
Corrosive gas can chemically damage the polariser and
the circuitry parts and eventually will cause defects.
•Keep the suitable temperature and humidity: High
temperatures and high humidity will shorten the lifetime

4.1 General
4.1.1 Warnings
• Figures can deviate due to the different module executions.
• During repair, place the set face down on a soft surface
(e.g. on foam bars as mentioned in next paragraph), in
order to prevent damaging the display.
Note: With some chassis, it is possible to measure and
replace the boards while the TV is still on its stand.
• All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD w). Careless handling
during repair can reduce life drastically. Make sure that,
during repair, you are connected with the same potential as
the mass of the set by a wristband with resistance. Keep
components and tools also at this same potential.
Figure 4-1 ESD wristband
• Be careful during measurements in the high voltage
section. Never pull plugs out under operation conditions,
just to prevent danger caused by electrical sparks.
• Never replace modules or other components while the unit
is switched “on”.
• Connectors “to” and “from” the Inverter Boards must be
thoroughly connected to avoid any electrical sparks during
operation.
4.1.2 Foam Bars
Figure 4-2 Foam bars
The foam bars (order code 3122 785 90580 for two pieces) can
be used for all types and sizes of flat displays. See figure
“Foam bars” for details. Displays with a size of 42” and larger,
require four foam bars [1]. Ensure that the foam bars are
always supporting the cabinet and never only the display.
Caution: Failure to follow these guidelines can seriously
damage the display!
By laying the TV face down on the (ESD protective) foam bars,
a stable situation is created to perform measurements and
alignments. By placing a mirror under the display, you can
monitor the screen.
