1. General Information
1-1 General Guidelines
When servicing, observe the original lead dress. If a short circuit is found, replace all parts which
have been overheated or damaged by the short circuit.
After servicing, see to it that all the protective devices such as insulation barriers, insulation papers
shields are properly installed.
After servicing, make the following leakage current checks to prevent the customer from being
exposed to shock hazards.
1) Leakage Current Cold Check
2) Leakage Current Hot Check
3)Prevention of Electro Static Discharge(ESD)to Electrostatically Sensitive

1-2 Important notice

1-2-1. Follow the regulations and warnings
Most important thing is to list up the potential hazard or risk for the service personnel to open the
units and disassemble the units. For example, we need to describe properly how to avoid the
possibility to get electrical shock from the live power supply or charged electrical parts (even the
power is off).
This symbol indicates that high voltage is present inside. It is dangerous to
make any king of contact with any inside part of this product.

This symbol indicates that there are important operating and maintenance
instructions in the literture accompanying the appliance
1-2-2. Be careful to the electrical shock
To prevent damage which might result in electric shock or fire, do not expose this TV set to rain or
excessive moisture. This TV must not be exposed to dripping or splashing water, and objects
Filled with liquid, such as vases, must not be place on top of or above the TV
1-2-3. Electro static discharge (ESD)
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such
Components commonly are called Electrostatically Sensitive (ES) Devices. The following
tech-niquesshouldbeusedtohelpreducetheincidenceofcomponentdamagecausedbyelectro
Static discharge (ESD).
1-2-4. About lead free solder (PbF)
This product is manufactured using lead-free solder as a part of a movement within the consum-er
products industry at large to be environmentally responsible. Lead-free solder must be used in the
servicing and repair of this product.
1-2-5. Use the genewing parts (specified parts)
Special parts which have purposes of fire retardant (resistors),high-quality sound (capacitors), low
noise(resistors), etc. are used.
When replacing any of components, be sure to use only manufacture's specified parts shown in
the parts list.
Safety Component
● Components identified by mark have special characteristics important for safety.

1-2-6. Take Care to Deal With The Cathode-Ray Tube
In the condition that an explosion-proof cathoderay tube is set in this equipment, safety is se-cured

against implosion. However, when removing it or serving from backward, it is dangerous to give a

shock. Take enough care to deal with it.

1-2-7. Safety Check after Repairment

Confirm that the screws ,parts and wiring which were removed in order to service are put in the

original positions, or whether there are the portions which are deteriorated around the serviced

places serviced or not. Check the insulation between the antenna terminal or external metal and

the AC cord plug blades. And be sure the safety of that.

Insuration Test
1. Unplug the plug from the AC outlet.
2. Remove the antenna terminal on TV and turn on the TV.
3. Insulation resistance between the cord plug terminals and the eternal exposure metal
should be more than M ohm by using the 500V insulation resistance meter
4. If the insulation resistance is less than M ohm, the inspection repair should be required.
If you have not the 500V insulation resistance meter, use a Tester.
External exposure metal: Antenna terminal Headphone jack

5-1 External Equipment Connections

Antenna Connection
Connect one end of a coaxial cable (not included) to the ANT IN jack on the back of your TV/DVD
combo, then connect the other end of the cable into the antenna or cable TV wall outlet.

To improve picture quality from an antenna in a poor signal area, install a signal amplifier.

If you need to split the antenna signal to connect two TVs, install a two-way splitter.
Choose Your Connection
There are several ways to connect your television, depending on the components you want to
connect
and the quality of the signal you want to achieve. The following are examples of some different
ways to connect your TV with different input sources. Choose the connection which is best for you.

LCD-TV.Tighten the screws on the PC
connectors once they are firmly
connected;
4.Turn on the power of the LCD-TV first ,
and then turn on the power of the PC;
5.Press INPUT button to set the video input mode of the LCD-TV to PC;
Once the input for PC is selected and if you see no image press function
F8 on you pc.
6.Check the image on your TV. There may be noise associated with the resolution,
vertical pattern, contrast or brightness in PC mode. If noise is present, change
the PC mode to another resolution, change the refresh rate to another rate or
adjust the brightness and contrast on the menu until the picture is clear. If the
refresh rate of the PC graphic card can not be changed, change the PC graphic
card or consult the manufacturer of the PC graphic card.
