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
Ɣ 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

Using the remote control
Installing remote control batteries
To install remote control batteries:
1 Open the battery compartment cover by pressing the release
button.
2 Insert two AA batteries into the battery compartment. Make sure
that the + and – symbols on the batteries match the + and –
symbols in the battery compartment.
3 Replace the cover.
Notes:
Do not mix different types of batteries.
Do not mix old and new batteries.
Remove batteries when they no longer have a charge. Chemicals may leak
into the battery compartment. Battery chemicals can cause a rash. If
chemicals leak, clean the battery compartment with a cloth.
Remove the batteries if you do not intend to use the remote control for an
extended amount of time.
Do not dispose of batteries in a fire. Dispose of them as hazardous waste.
Tips:
Aiming the remote control
To use the remote control:
• Point the remote control towards the remote sensor on the front
of your TV. The remote control’s range is about 26 ft. (8 m).
• The brand name is often visible on the front of the universal remote
control, and the model number is often visible on the back.
• If your universal remote control isn’t listed on the chart, refer to your
universal remote control’s instructions and try codes for the brands
Orion, Emerson, Memorex, Sansui, Sylvania, or Zenith. You may need
to try several codes before finding a match.
2 Follow your universal remote control’s instructions to enter the
code you found in Step 1.
Tips:
• If your universal remote control has a code search feature, run a code
search to identify a code that matches your TV. See your universal
remote control’s instructions for details.
• If your universal remote control has a “Learn” feature, you can
manually program it using your TV remote to “teach” the commands
one at a time. See your universal remote control’s instructions for
details.
Notes:
Do not expose the remote control to shock or liquids.
Do not use the remote control in an area with high humidity.
Do not place the remote control in direct sunlight.
Do not place objects, such as furniture, between the remote control and
the remote sensor.
The remote control may not work if direct sunlight or bright light shines on
the remote sensor. Either move your TV or change the angle at which
you use the remote control.
Programming a universal remote control
to work with your TV
You can operate your TV with a new or existing universal remote
control.
To program a universal remote control:
1 Find the code for your universal remote control by identifying its
model (or your set-top box’s remote control manufacturer and
model) on the charts below, then make note of the numbered
code below it. You will use the numbered code to program your
remote control to work with your TV.

models are available in the market.
