SAFETY PRECAUTION

IMPORTANT SERVICE SAFETY PRECAUTION

■ 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 AGAINST A

RISK OF FIRE REPLACE ONLY WITH SAME
TYPE FUSE.
42" F901 (T6.3AH/250V)

26"/32" F901 (T5AH/250V)

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 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.

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

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.

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

• Use an AC voltmeter having with 5000 ohm per volt, 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 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.

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.

Precautions for using lead-free solder

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 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.

Preparation

Attaching/Detaching the Stand

• Before attaching (or detaching) the stand, unplug the AC cord from the AC INPUT terminal.

• Before performing work spread cushioning over the base area to lay the TV on. This will prevent it from
Being damaged.

CAUTION:

• Attach the stand in the correct direction.

• Be sure to follow the instructions. Incorrect installation of the stand may result in the TV falling over.

1. Put the TV face down on a safe surface

that is covered by a soft and smooth cloth.

2. Adjust the TV stand to the bottom of the TV.

3. Fasten the screws by using a cross-head screwdriver(Not supplied).
CAUTION:

• Do not push to hard or put excessive pressure to the stand neck to avoid the damages when you turn the TV for the most comfortable viewing
angle.
NOTE:

To detach the TV stand, perform the steps in reverse order.

Installing Batteries in the Remote Control Unit

1. Insert two AAA batteries into Remote control. Make sure (+) and (-) are facing the proper
direction.

2. Replace the cover

NOTE

• If the remote control will not to be used for a long time, remove the batteries to avoid remote control

damage.

CAUTION:

Improper use of batteries can result in chemical leakage or explosion. Be sure to follow the instructions below.

• Do not mix batteries of different types. Different types of batteries have different characteristics.

• Do not mix old and new batteries. Mixing old and new batteries can shorten the life of new batteries or cause chemical leakage in old batteries.

• Remove batteries as soon as they are worn out. Chemicals that leak from batteries come in contact with skin can cause a rash. If you find any chemical

leakage, wipe thoroughly with a cloth.

• The batteries supplied with this product may have a shorter life expectancy due to storage conditions.

• If you will not be using the remote control unit for an extended period of time, remove batteries from it.

Note on disposing batteries:

The batteries provided contain no harmful materials such as cadmium, lead or mercury. Regulations concerning used batteries stipulate that batteries may
no longer be thrown out with the household rubbish. Deposit any used batteries free of charge into the designated collection containers set up at
commercial businesses.

Installing Batteries in the Remote Control Unit

Use the remote control unit by pointing it towards the remote control sensor. Objects
between the remote control unit and sensor may prevent proper operation.
