2. Caution
No modification of any circuit should be attempted. Service work should only be performed after
you are thoroughly familiar
with all of the following safety checks and servicing guidelines.
3. Safety Check
Care should be taken while servicing this Multimedia TV display. Because of the high voltage used
in the inverter circuit, the voltage is exposed in such areas as the associated transformer circuits.
4. Power Supply Requirements
The external AC power operating range shall be from 90 to 264Vac.
5. Multimedia TV Handling Precautions
5.1. 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) Wipe off water drop immediately. Long contact 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 Multimedia TV.
(11) After installation of the Multimedia TV into an enclosure, do not twist nor bend the
Multimedia TV even momentary. At designing the enclosure, it should be taken into
consideration that no bending/twisting forces are applied to the Multimedia TV from
outside. Otherwise the Multimedia TV may be damaged.
(12) Cold cathode fluorescent lamp in Multimedia TV 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 Multimedia TV.
The Multimedia TV should be supplied by power complied with requirements of
Limited Power Source, or be applied exemption.
