1. Precautions
1-1. Safety Precautions
Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such as
electrical shock.
1-1-1. Warnings
For continued safety, do not attempt to modify the circuit board.
WARNING
1-1-2. Servicing the LED Monitor
When servicing the LED Monitor, Disconnect the AC line cord from the AC outlet.1.
It is essential that service technicians have an accurate voltage meter available at all times. Check the calibration of this 2.
meter periodically.
1-1-3. Fire and Shock Hazard
Before returning the monitor to the user, perform the following safety checks:
Inspect each lead dress to make certain that the leads are not pinched or that hardware is not lodged between the chassis 1.
and other metal parts in the monitor.
Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet backs, adjustment and 2.
compartment covers or shields, isolation resistorcapacitor networks, mechanical insulators, etc.
Leakage Current Hot Check:3.
Disconnect the AC power and DC power jack before servicing.

Use a leakage current tester or a metering system that complies with American National Standards
WARNING
Institute (ANSI C101.1, Leakage Current for Appliances), and Underwriters Laboratories (UL Publication
UL1410, 59.7).
With the unit completely reassembled, plug the AC line cord directly into a 120V AC outlet. With the unit’s AC switch rst in 4.
the ON position and then OFF, measure the current between a known earth ground (metal water pipe, conduit, etc.) and all
exposed metal parts, including: metal cabinets, screwheads and control shafts.
The current measured should not exceed 0.5 milliamp.
Reverse the power-plug prongs in the AC outlet and repeat the test.
1-1-4. Product Safety Notices
Some electrical and mechanical parts have special safetyrelated 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 identied 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,
re and/or other hazards. Product safety is under review continuously and new instructions are issued whenever appropriate.

1. Precautions 1. Precautions
1-2. Servicing Precautions
An electrolytic capacitor installed with the wrong polarity might explode.
WARNING
Before servicing units covered by this service manual, read and follow the Safety Precautions section of
CAUTION
NOTE
1-2-1. General Servicing Precautions
Always unplug the unit’s AC power cord from the AC power source and disconnect the DC Power Jack before attempting to: 1.
(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.
Some components are raised above the printed circuit board for safety. An insulation tube or tape is sometimes used. The 2.
internal wiring is sometimes clamped to prevent contact with thermally hot components. Reinstall all such elements to their
original position.
After servicing, always check that the screws, components and wiring have been correctly reinstalled. Make sure that the 3.
area around the serviced part has not been damaged.
Check the insulation between the blades of the AC plug and accessible conductive parts (examples: metal panels, input 4.
terminals and earphone jacks).
Insulation Checking Procedure: Disconnect the power cord from the AC source and turn the power switch ON. 5.
Connect an insulation resistance meter (500 V) to theblades 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.
Always connect a test instrument’s ground lead to the instrument chassis ground before connecting the positive lead; 6.
always remove the instrument’s ground lead last.
this manual.
If unforeseen circumstances create conict between the following servicing precautions and any of the
safety precautions, always follow the safety precautions.
Page 12
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 eld-effect
transistors. The following techniques will reduce the incidence of component damage caused by static electricity.
Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from your body 1.
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.
After removing an ESD-equipped assembly, place it on a conductive surface such as aluminum foil to prevent accumulation 2.
of an electrostatic charge.
Do not use freon-propelled chemicals. These can generate electrical charges sufcient to damage ESDs.3.
Use only a grounded-tip soldering iron to solder or desolder ESDs.4.
Use only an anti-static solder removal device. Some solder removal devices not classied as “anti-static” can generate 5.
electrical charges sufcient to damage ESDs.
Do not remove a replacement ESD from its protective package until you are ready to install it. Most replacement ESDs are 6.
packaged with leads that are electrically shorted together by conductive foam, aluminum foil or other conductive materials.
Immediately before removing the protective material from the leads of a replacement ESD, touch the protective material to 7.
the chassis or circuit assembly into which the device will be installed.
Be sure no power is applied to the chassis or circuit and observe all other safety precautions.
CAUTION
Minimize body motions when handling unpackaged replacement ESDs. Motions such as brushing clothes together, 8.
or lifting your foot from a carpeted oor can generate enough static electricity to damage an ESD.

1. Precautions 1. Precautions
1-4. Installation Precautions
For safety reasons, more than a people are required for carrying the product.1.
Keep the power cord away from any heat emitting devices, as a melted covering may cause re or electric shock.2.
Do not place the product in areas with poor ventilation such as a bookshelf or closet. The increased internal temperature 3.
may cause re.
Bend the external antenna cable when connecting it to the product. This is a measure to protect it from being exposed to 4.
moisture. Otherwise, it may cause a re or electric shock.
Make sure to turn the power off and unplug the power cord from the outlet before repositioning the product. Also check the 5.
antenna cable or the external connectors if they are fully unplugged. Damage to the cord may cause re or electric shock.
Keep the antenna far away from any high-voltage cables and install it rmly. Contact with the highvoltage cable or the 6.
antenna falling over may cause re or electric shock.
When installing the product, leave enough space (0.4m) between the product and the wall for ventilation purposes. 7.
A rise in temperature within the product may cause re.
If an equipment is provided with a replaceable battery, and if replacement by an incorrect type could result in an 8.
explosion (for example, with some lithium batteries), the following applies:
RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE.
CAUTION
DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.

4-4. Adjustment
4-4-1. Service Instruction
Usually, a color TV-VCR needs only slight touch-up adjustment upon installation. Check the basic characteristics such 1.
as height, horizontal and vertical sync.
Use the specied test equipment or its equivalent.2.
Correct impedance matching is essential.3.
Avoid overload. Excessive signal from a sweep generator might overload the front-end of the TV. When inserting signal 4.
markers, do not allow the marker generator to distort test result.
Connect the TV only to an AC power source with voltage and frequency as specied on the backcover nameplate.5.
Do not attempt to connect or disconnect any wire while the TV is turned on. Make sure that the power cord is 6.
disconnected before replacing any parts.
To protect aganist shock hazard, use an isolation transform.7.
