SAFETY PRECAUTION
IMPORTANT SERVICE SAFETY PRECAUTION
WARNING
1. For continued safety, no modification of any circuit should be
attempted.
2. Disconnect AC power before servicing.
BEFORE RETURNING THE RECEIVER
(Fire & Shock Hazard)
Before returning the receiver to the user, perform the following
safety checks:
3. Inspect all lead dress to make certain that leads are not pinched,
and check that hardware is not lodged between the chassis and
other metal parts in the receiver.
4. Inspect all protective devices such as non-metallic control knobs,
insulation materials, cabinet backs, adjustment and compartment
covers or shields, isolation resistor-capacitor networks, mechanical
insulators, etc.
5. To be sure that no shock hazard exists, check for leakage current in
the following manner.
• Plug the AC cord directly into a 220~240 volt AC outlet.
• Using two clip leads, connect a 1.5k ohm, 10 watt resistor paral-
leled by a 0.15µF capacitor in series with all exposed metal cabinet
parts and a known earth ground, such as electrical conduit or elec-
trical ground connected to an earth ground.
• Use an AC voltmeter having with 5000 ohm per volt, or higher, sen-
sitivity or measure the AC voltage drop across the resistor.
• Connect the resistor connection to all exposed metal parts having a
return to the chassis (antenna, metal cabinet, screw heads, knobs
and control shafts, escutcheon, etc.) and measure the AC voltage
drop across the resistor.
All checks must be repeated with the AC cord plug connection
reversed. (If necessary, a nonpolarized adaptor plug must be used
only for the purpose of completing these checks.)
Any reading of 1.05 V peak (this corresponds to 0.7 mA peak AC.)
or more is excessive and indicates a potential shock hazard which
must be corrected before returning the monitor to the owner.
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
SAFETY NOTICE
Many electrical and mechanical parts in LCD color television have
special safety-related characteristics.
These characteristics are often not evident from visual inspection, nor
can protection afforded by them be necessarily increased by using
replacement components rated for higher voltage, wattage, etc.
Replacement parts which have these special safety characteristics are
identified in this manual; electrical components having such features
are identified by “ ” and shaded areas in the Replacement Parts
List and Schematic Diagrams.
For continued protection, replacement parts must be identical to those
used in the original circuit.
The use of a substitute replacement parts which do not have the same
safety characteristics as the factory recommended replacement parts
shown in this service manual, may create shock, fire or other hazards.
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Service work should be performed only by qualified service technicians who are thoroughly familiar with all safety checks and the
servicing guidelines which follow:
CAUTION:
FOR CONTINUED PROTECTION AGAINST A
RISK OF FIRE REPLACE ONLY WITH SAME

Precautions for using lead-free solder
Employing lead-free solder
• “PWBs” of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the PWBs and service manuals. The
alphabetical character following LF shows the type of lead-free solder.
Example:
Using lead-free wire solder
• When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder may cause dam-
age or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 °C, we recommend you to use a dedicated soldering
bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station or service branch in your area.
Soldering
• As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 °C which is higher than the conventional lead solder by 40 °C, and as it has poor
solder wettability, you may be apt to keep the soldering bit in contact with the PWB for extended period of time. However, Since the land may be
peeled off or the maximum heat-resistance temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm the
steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on and off the power of the bit as
required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
• Be careful when replacing parts with polarity indication on the PWB silk.

CAUTION: (1) As for handling, wear clean gloves, protective footwear-
and mask.
(2) Inner gloves are covered in the Nitrile gloves.
(3) Nitrile gloves are exchanged with the following
standard.
• When it touched a face and so on.
• When another work was done.
• By the work of fifty times.
• In the time for recess.
• When it became dirty.
• When it tore.
(4)Have a designated place at the time of the handling.
Back side : Black print part
Front side : Protection tape part
You must not have a clear surface.
(5) Two people have handling equally by the work.
(Maintain it so that glass is not warped.)

Check the order due to workability.
*Note: Do not bend the PWB (FPCB section)
and sheet (ITO section).
