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 UseEN 4 LCD CPT 2K73.

• 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 �). 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.

11.2. Handling precaution

(1) Don’t disassemble and reassemble the module by self. (2) Acid, alkali, alcohol or touched directly by hand will damage the display.

(3) Static electricity will damage the module. Please configure grounding device.

(4) The strong vibration, shock, twist or bend will cause material damage, even module broken.

(5) It is easy to cause image sticking while displaying the same pattern for very long time.

(6) The response time, brightness and performance will vary from different temperature.

(7) The inverter will cause high temperature and high voltage, be careful please.



12. HANDLING PRECAUTIONS FOR TFT-LCD MODULE Please pay attention to the followings in handling TFT-LCD products； 12.1 ASSEMBLY PRECAUTION

(1) Please use the mounting hole on the module side in installing and do not beading or wrenching LCD in assembling. And please do not drop, bend or twist LCD module in handling.

(2) Please design display housing in accordance with the following guidelines. • Housing case must be destined carefully so as not to put stresses on LCD all sides and not to

wrench module. The stresses may cause non-uniformity even if there is no non-uniformity statically.

• Keep sufficient clearance between LCD module back surface and housing when the LCD module is mounted. Approximately 1.0 mm of the clearance in the design is recommended taking into account the tolerance of LCD module thickness and mounting structure height on the housing.

• When some parts, such as, FPC cable and ferrite plate, are installed underneath the LCD module, still sufficient clearance is required, such as 0.5mm. This clearance is, especially, to be reconsidered when the additional parts are implemented for EMI countermeasure.

• Design the inverter location and connector position carefully so as not to give stress to lamp cable, or not to interface the LCD module by the lamp cable.

• Keep sufficient clearance between LCD module and the others parts, such as inverter and speaker so as not to interface the LCD module. Approximately 1.0mm of the clearance in the design is recommended.

(3) Please do not push or scratch LCD panel surface with any-thing hard. And do not soil LCD panel surface by touching with bare hands. (Polarizer film, surface of LCD panel is easy to be flawed.)

(4) Please do not press any parts on the rear side such as source TCP, gate TCP, control circuit board and FPCs during handling LCD module. If pressing rear part is unavoidable, handle the LCD module with care not to damage them.

(5) Please wipe out LCD panel surface with absorbent cotton or soft clothe in case of it being soiled. (6) Please wipe out drops of adhesives like saliva and water on LCD panel surface immediately. They

might damage to cause panel surface variation and color change. (7) Please do not take a LCD module to pieces and reconstruct it. Resolving and reconstructing

modules may cause them not to work well. (8) Please do not touch metal frames with bare hands and soiled gloves. A color change of the metal

frames can happen during a long preservation of soiled LCD modules. (9) Please pay attention to handling lead wire of backlight so that it is not tugged in connecting with

inverter. 12.2 OPERATING PRECAUTIONS

(1) Please be sure to turn off the power supply before connecting and disconnecting signal input cable. (2) Please do not change variable resistance settings in LCD module. They are adjusted to the most

suitable value. If they are changed, it might happen LCD does not satisfy the characteristics specification.

(3) Please consider that LCD backlight takes longer time to become stable of radiation characteristics in low temperature than in room temperature.

(4) A condensation might happen on the surface and inside of LCD module in case of sudden change of ambient temperature.

(5) Please pay attention to displaying the same pattern for very long time. Image might stick on LCD. If then, time going on can make LCD work well.

(6) Please obey the same caution descriptions as ones that need to pay attention to ordinary electronic parts.



12.3 PRECAUTIONS WITH ELECTROSTATICS (1) This LCD module use CMOS-IC on circuit board and TFT-LCD panel, and so it is easy to be

affected by electrostatics. Please be careful with electrostatics by the way of your body connecting to the ground and so on.

(2) Please remove protection film very slowly on the surface of LCD module to prevent from electrostatics occurrence.

12.4 STORAGE PRECAUTIONS

(1) When you store LCDs for a long time, it is recommended to keep the temperature between 0℃ ~40℃ without the exposure of sunlight and to keep the humidity less than 90%RH.

(2) Please do not leave the LCDs in the environment of high humidity and high temperature such as 60℃ 90%RH.

(3) Please do not leave the LCDs in the environment of low temperature; below -20℃. 12.5 SAFETY PRECAUTIONS

(1) When you waste LCDs, it is recommended to crush damaged or unnecessary LCDs into pieces and wash them off with solvents such as acetone and ethanol, which should later be burned.

(2) If any liquid leaks out of a damaged-glass cell and comes in contact with the hands, wash off throughly with soap and water.

12.6 OTHERS

(1) A strong incident light into LCD panel might cause display characteristics' changing inferior because of polarizer film, color filter, and other materials becoming inferior. Please do not expose LCD module direct sunlight Land strong UV rays.

(2) Please pay attention to a panel side of LCD module not to contact with other materials in preserving it alone.

(3) For the packaging box, please pay attention to the followings: • Packaging box and inner case for LCD are designed to protect the LCDs from the damage or

scratching during transportation. Please do not open except picking LCDs up from the box. • Please do not pile them up more than 3 boxes. (They are not designed so.) And please do not

turn over. • Please handle packaging box with care not to give them sudden shock and vibrations. And also

please do not throw them up. • Packing box and inner case for LCDs are made of cardboard. So please pay attention not to get

them wet. (Such like keeping them in high humidity or wet place can occur getting them wet.)
