Introduction

This manual provides an integral technical information you need to maintain the LCD Monitor.
And this manual is applied to the model of 1024 x 768 pixels color TFT LCD Monitor with a 15”
flat pa nel screen. There are six topics in this ma nual, a nd you can i mmediately identify problems through this
ma nual.

This manual is for the technicians and people who have the electronic background. Send the
product back to the distributor for re pairing and do not attempt to do anything which is complex or
not mentioned in the troubleshooting.

1-1.2 LCD Module Handling Precautions

1) Since front polarizer is easily damaged, pay attention not to scratch it.

2) Be sure to turn off power supply when inserting or disconnecting from input connector.

3) Wi pe off water drop i mmediately . Long conta ct with water may cause discoloration or spots.

4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.

5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface.

6) Since CMOS LSI is used in this module, take care of static electricity and insure human earth
when handling.

7) Do not open nor modify the Module Assembly .

8) Do not press the reflector sheet at the back of the module to any directions.

9) In case if a Module has to be put back into the packing container slot after once it was taken out
from the container, do not press the center of the CCFL Reflector edge. Instead, press at the far
ends of the CFL Reflector edge softly. Otherwise the TFT Module may be damaged.

10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor tilt the
Interface Connector of the TFT Module.

11) After installation of the TFT Module into an enclosure (LCD monitor housing, for example), do not
twist nor bend the TFT Module even momentary . At designing the enclosure, it should be taken
into consideration that no bending/twisting forces are applied to the TFT Module from outside.
Otherwise the TFT Module may be damaged.

12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please follow local
ordinances or regulations for disposal.

13) Small amount of materials having no flammability grade is used in the LCD module.
The LCD module should be supplied by power complied with requirements of Limited Power Source
(IEC60950 or UL1950), or be applied exemption.

14) The LCD module is designed so that the CFL in it is supplied by Limited Current
Circuit(IEC60950 or UL1950). Do not connect the CFL in Hazardous Voltage Circuit.

1-1.3 Handling and Placing Methods

Correct Methods:

Only touch the metal frame of the
LCD panel or the front cover of the
monitor . Do not touch the surfa ce of
the polarizer.

Incorrect Methods:

Surface of the LCD pa nel is pressed
by fingers a nd that will probably
cause “Mura.”

T ake out the monitor with cushions

T aking out the monitor by grasping the LCD
pa nel. That will probably cause “Mura.”

Place the monitor on a clean a nd soft foa m pad.

Placing the monitor on f oreign objects. That will
probably scratch the surfa ce of the pa nel or cause
“Mura.”

Coretronic Corporation

The pa nel is placed fa cedown on the lap. That
will probably cause “Mura.”
