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 120 volt AC outlet.

• Using two clip leads, connect a 1.5k ohm, 10 watt resistor paral-

leled by a 0.15PF 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 0.75 Vrms (this corresponds to 0.5 mA rms 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: FO R CO NT IN UED PROTECTION

AGAINST A RISK OF FIRE REPLACE ONLY WITH

SAME TYPE FUSE.

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 qC, 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 qC which is higher than the conventional lead solder by 40 qC, 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.

Lead-free wire solder for servicing

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

3. Entering and exiting the adjustment process mode

1) Before entering the adjustment process mode, the AV position RESET in the video adjustment menu.

2) While holding down the “VOL (–)” and “ENTER” keys at a time, plug in the AC cord of the main unit to turn on the power.

The letter “S” appears on the screen.

3) Next, hold down the “VOL (–)” and “CH ( )” keys at a time.

(The “VOL (–)” and “CH ( )” keys should be pressed and held until the display appears.)

Multiple lines of blue characters appearing on the display indicate that the unit is now in the adjustment process mode.

When you fail to enter the adjustment process mode (the display is the same as normal startup), retry the procedure.

4) To exit the adjustment process mode after the adjustment is done, unplug the AC cord from the outlet to make a forced shutdown. (When the

power was turned off with the remote controller, once unplug the AC cord and plug it again. In this case, wait 10 seconds or so before plugging.)

CAUTION: Use due care in handling the information described here lest your users should know how to enter the adjustment process mode. If the

settings are tampered in this mode, unrecoverable system damage may result.
