IMPORTANT SERVICE SAFETY PRECAUTION

Ë

Service work should be performed only by qualified service technicians who are thor­oughly familiar with all safety checks and the servicing guidelines which follow:

WARNING

1. For continued safety, no modification of any circuit
should be attempted.

2. Disconnect AC power before servicing.

CAUTION: FOR CONTINUED
PROTECTION A GAINST A RISK OF
FIRE REPLACE ONLY WITH SAME
TYPE F3701 (2.0A, 250V), F3702
(1.25A, 250V), F6700 (1.25A, 250V),

A V

F6701 (1.25A, 125V), F6702 (1.25A,
250V), F6703 (1.25A, 250V) AND
F6704 (1.25A, 250V) FUSE.

BEFORE RETURNING THE RECEIVER
(Fire & Shock Hazard)

Before returning the receiver to the user, perform
the following safety checks:

1. 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.

2. 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.

3. To be sure that no shock hazard exists, check for
leakage current in the following manner.

• Plug the AC cord directly into a 110~240 volt A C outlet,
and connect the DC power cable into the receiv er's DC
jack. (Do not use an isolation tr ansformer for this test).

• Using two clip leads, connect a 1.5k ohm, 10 watt
resistor paralleled by a 0.15µF capacitor in series with
all exposed metal cabinet parts and a known earth
ground, such as electrical conduit or electrical ground
connected to an earth ground.

• Use an AC voltmeter ha ving with 5000 ohm per v olt, or
higher, sensitivity 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 0.75V peak (this corresponds to 0.5 mA.
peak AC.) or more is e xcessive 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 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

and shaded areas in the

Schematic Diagrams

For continued protection, replacement parts must be
identical to those used in the original circuit.

Precautions for using lead-free solder

1 Employing lead-free solder

"All 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:

L Fa

Indicates lead-free solder of tin, silver and copper.

2 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 damage 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 ho w to obtain lead-free wire solder or soldering bit,
contact our service station or service branch in your area.

3 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, remov e the bit from the PWB as soon as y ou 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 allo y ed 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.

1. Go to the adjustment mode.

1. Receive a B/W channel.

2. Go to the adjustment mode.

3. Select the "COM BIAS" with
[MENU] key.

1. Receive a half color bar signal in the
TV mode so that the top left zone
should turn white 75% as shown be­low. Other signal can be fed instead
of the half color bar signal, howev er,
if the point at the vertical 180th line
and horizontal 46th pixel is of white
75%. (Make the adjustment based
on the setting of this point.)

1. Adjust the "B+ Adj" value to

5.0±0.02V with R3714. Make exact
adjustment of the 5.00V level be­cause it will be the reference for all
the other supply voltages. Be sure to
make this adjustment together with
the main PWB (digital PWB). During
the adjustment, be also careful not
to allow the voltage at pin (2) of
P3701 to go above 5.3 V.

1. Select "INCH SIZE" and adjust to
"20" with "VOL (+)" or "VOL (–)" key.

* The color of "INCH SIZE" must be

yellow.

1. Adjust "COM BIAS" to the darkest
screen with "VOL (+)" and "VOL (–)"
key.

* The color of "COM BIAS" must be

yellow.
