Samsung Electronics Co., Ltd.
Any unauthorized use of Manual can be
punished under applicable International
and/or domestic law.

1 Precautions

1-1

1-1-1 Warnings

1. For continued safety, do not attempt to modify the
circuit board.

2. Disconnect the AC power and DC Power Jack before
servicing.

1-1-2 Ser vicing the LCD Monitor

1. When servicing the LCD Monitor Disconnect the AC
line cord from the AC outlet.

2. It is essential that service technicians have an accurate
voltage meter available at all times. Check the
calibration of this meter periodically.

1-1-3 Fire and Shock Hazard

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

1. Inspect each lead dress to make certain that the leads
are not pinched or that hardware is not lodged between
the chassis and other metal parts in the monitor.

2. Inspect all protective devices such as nonmetallic
control knobs, insulating materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacitor networks, mechanical
insulators, etc.

3. Leakage Current Hot Check (Figure 1-1):

WARNING: Do not use an isolation

transformer during
this test.

Use a leakage current tester or a metering system that
complies with American National Standards Institute
(ANSI C101.1, Leakage Current for Appliances), and
Underwriters Laboratories (UL Publication UL1410,

59.7).

Figure 1-1. Leakage Current Test Circuit

1-1-4 Product Safety Notices

Some electrical and mechanical parts have special
safety-related characteristics which are often not evident
from visual inspection. The protection they give may not
be obtained by replacing them with components rated for
higher voltage, wattage, etc. Parts that have special safety
characteristics are identified by on schematics and parts
lists. A substitute replacement that does not have the same
safety characteristics as the recommended replacement part
might create shock, fire and/or other hazards. Product
safety is under review continuously and new instructions
are issued whenever appropriate.

1 Precautions

Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such as electrical shock.

1-1 Safety Precautions

1 Precautions

1-2

1-2-1 General Ser vicing

Precautions

1. Always unplug the units AC power cord from the AC
power source and disconnect the DC Power Jack
before attempting to:
(a) remove or reinstall any component or assembly, (b)
disconnect PCB plugs or connectors, (c) connect a test
component in parallel with an electrolytic capacitor.

2. Some components are raised above the printed circuit
board for safety. An insulation tube or tape is
sometimes used. The internal wiring is sometimes
clamped to prevent contact with thermally hot
components. Reinstall all such elements to their
original position.

3. After servicing, always check that the screws,
components and wiring have been correctly
reinstalled. Make sure that the area around the
serviced part has not been damaged.

1. Immediately before handling any semiconductor
components or assemblies, drain the electrostatic
charge from your body by touching a known earth
ground. Alternatively, wear a discharging wrist-strap
device. To avoid a shock hazard, be sure to remove the
wrist strap before applying power to the monitor.

2. After removing an ESD-equipped assembly, place it
on a conductive surface such as aluminum foil to
prevent accumulation of an electrostatic charge.

3. Do not use freon-propelled chemicals. These can
generate electrical charges sufficient to damage ESDs.

4. Use only a grounded-tip soldering iron to solder or
desolder ESDs.

5. Use only an anti-static solder removal device. Some
solder removal devices not classified as anti-static
can generate electrical charges sufficient to damage
ESDs.

4. Check the insulation between the blades of the AC
plug and accessible conductive parts (examples: metal
panels, input terminals and earphone jacks).

5. Insulation Checking Procedure: Disconnect the power
cord from the AC source and turn the power switch
ON. Connect an insulation resistance meter (500 V) to
the blades of the AC plug.

The insulation resistance between each blade of the
AC plug and accessible conductive parts (see above)
should be greater than 1 megohm.

6. Always connect a test instruments ground lead to the
instrument chassis ground before connecting the
positive lead; always remove the instruments ground
lead last.

6. Do not remove a replacement ESD from its protective
package until you are ready to install it. Most
replacement ESDs are packaged with leads that are
electrically shorted together by conductive foam,
aluminum foil or other conductive materials.

7. Immediately before removing the protective material
from the leads of a replacement ESD, touch the
protective material to the chassis or circuit assembly
into which the device will be installed.

Caution: Be sure no power is applied to

the chassis or circuit and
observe all other safety
precautions.

8. Minimize body motions when handling unpackaged
replacement ESDs. Motions such as brushing clothes
together, or lifting your foot from a carpeted floor can
generate enough static electricity to damage an ESD.

1-3 Static Electricity Precautions

Some semiconductor (solid state) devices can be easily damaged by static electricity. Such components are commonly called
Electrostatically Sensitive Devices (ESD). Examples of typical ESD are integrated circuits and some field-effect transistors.
The following techniques will reduce the incidence of component damage caused by static electricity.

1-2 Ser vicing Precautions

WARNING: An electrolytic capacitor installed with the wrong polarity might explode.
Caution: Before servicing units covered by this service manual, read and follow the Safety

Precautions section of this manual.

Note: If unforeseen circumstances create conflict between the following servicing precautions and any of the safety

precautions, always follow the safety precautions.

1. For safety reasons, more than two people are
required for carrying the product.

2. Keep the power cord away from any heat emitting
devices, as a melted covering may cause fire or
electric shock.

3. Do not place the product in areas with poor
ventilation such as a bookshelf or closet. The
increased internal temperature may cause fire.

4. Bend the external antenna cable when connecting
it to the product. This is a measure to protect it
from being exposed to moisture. Otherwise, it
may cause a fire or electric shock.

5. Make sure to turn the power off and unplug the
power cord from the outlet before repositioning
the product. Also check the antenna cable or the
external connectors if they are fully unplugged.
Damage to the cord may cause fire or electric
shock.

6. Keep the antenna far away from any high-voltage
cables and install it firmly. Contact with the high­voltage cable or the antenna falling over may
cause fire or electric shock.

7. When installing the product, leave enough space
(10cm) between the product and the wall for
ventilation purposes.
A rise in temperature within the product may
cause fire.

1. Usually, a color TV-VCR needs only slight touch-up adjustment upon installation.
Check the basic characteristics such as height, horizontal and vertical sync.

2. Use the specified test equipment or its equivalent.

3. Correct impedance matching is essential.

4. Avoid overload. Excessive signal from a sweep generator might overload the front-end
of the TV. When inserting signal markers, do not allow the marker generator to distort
test result.

5. Connect the TV only to an AC power source with voltage and frequency as specified on
the backcover nameplate.

6. Do not attempt to connect or disconnect any wire while the TV is turned on. Make sure
that the power cord is disconnected before replacing any parts.

7. To protect aganist shock hazard, use an isolation transform.
