Attention: This service manual is only for service personnel to take reference with. Before
servicing please read the following points carefully.
Safety precautions
1. Instructions
Be sure to switch off the power supply before replacing or welding any components or
inserting/plugging in connection wire Anti static measures to be taken (throughout the entire
production process!):
a) Do not touch here and there by hand at will;
b) Be sure to use anti static electric iron;
c) It’s a must for the welder to wear anti static gloves.
Please refer to the detailed list before replacing components that have special safety requirements.
Do not change the specs and type at will.
2. Points for attention in servicing of LCD
2.1 Screens are different from one model to another and therefore not interchangeable. Be sure to
use the screen of the original model for replacement.
2.2 The operation voltage of LCD screen is 700-825V. Be sure to take proper measures in
protecting yourself and the machine when testing the system in the course of normal operation or
right after the power is switched off. Please do not touch the circuit or the metal part of the module
that is in operation mode. Relevant operation is possible only one minute after the power is
switched off.
2.3 Do not use any adapter that is not identical with the TV set. Otherwise it will cause fire or
damage to the set.
2.4 Never operate the set or do any installation work in bad environment such as wet bathroom,
laundry, kitchen, or nearby fire source, heating equipment and devices or exposure to sunlight etc.
Otherwise bad effect will result.
2.5 If any foreign substance such as water, liquid, metal slices or other matters happens to fall into
the module, be sure to cut the power off immediately and do not move anything on the module lest it
should cause fire or electric shock due to contact with the high voltage or short circuit.
2.6 Should there be smoke, abnormal smell or sound from the module, please shut the power off at
once. Likewise, if the screen is not working after the power is on or in the course of operation, the
power must be cut off immediately and no more operation is allowed under the same condition.
2.7 Do not pull out or plug in the connection wire when the module is in operation or just after the
power is off because in this case relatively high voltage still remains in the capacitor of the driving
circuit. Please wait at least one minute before the pulling out or plugging in the connection wire.
2.8 When operating or installing LCD please don’t subject the LCD components to bending, twisting
or extrusion, collision lest mishap should result.
2.9 As most of the circuitry in LCD TV set is composed of CMOS integrated circuits, it’s necessary
to pay attention to anti statics. Before servicing LCD TV make sure to take anti static measure and
ensure full grounding for all the parts that have to be grounded.
2.10 There are lots of connection wires between parts behind the LCD screen. When servicing or
moving the set please take care not to touch or scratch them. Once they are damaged the screen
1
would be unable to work and no way to get it repaired.
If the connection wires, connections or components fixed by the thermotropic glue need to
disengage when service, please soak the thermotropic glue into the alcohol and then pull them out
in case of dagmage.
2.11 Special care must be taken in transporting or handling it. Exquisite shock vibration may lead to
breakage of screen glass or damage to driving circuit. Therefore it must be packed in a strong case
before the transportation or handling.
2.12 For the storage make sure to put it in a place where the environment can be controlled so as to
prevent the temperature and humidity from exceeding the limits as specified in the manual. For
prolonged storage, it is necessary to house it in an anti-moisture bag and put them altogether in one
place. The ambient conditions are tabulated as follows:
Temperature
Humidity
Scope for operation
0 ~ +50 oC
Scope for storage
-20 ~ +60 oC
Scope for operation
20% ~ 85%
Scope for storage
10% ~ 90%
2.13 Display of a fixed picture for a long time may result in appearance of picture residue on the
screen, as commonly called “ghost shadow”. The extent of the residual picture varies with the
maker of LCD screen. This phenomenon doesn’t represent failure. This “ghost shadow” may remain
in the picture for a period of time (several minutes). But when operating it please avoid displaying
still picture in high brightness for a long time.
3. Points for attention during installation
3.1 The front panel of LCD screen is of glass. When installing it please make sure to put it in place.
3.2 For service or installation it’s necessary to use specified screw lest it should damage the screen.
3.3 Be sure to take anti dust measures. Any foreign substance that happens to fall down between
the screen and the glass will affect the receiving and viewing effect
3.4 When dismantling or mounting the protective partition plate that is used for anti vibration and
insulation please take care to keep it in intactness so as to avoid hidden trouble.
3.5 Be sure to protect the cabinet from damage or scratch during service, dismantling or mounting.

Trouble shooting
1. Fault clearance
Before servicing please check to find the possible causes of the troubles according to the table
below.
1.1 Antenna (signal):
Picture is out of focus or jumping
Bad status in signal receiving
Poor signal
Check if there are failures with the electrical connector or
the antenna.
Check if the antenna is properly connected.
Fringe in picture
Check if the antenna is correctly oriented.
Maybe there is electric wave reflected from hilltop or
building.
Picture is interfered by stripe
Possibly due to interference from automobile, train, high
shaped bright spots
voltage transmission line, neon lamp etc.
Maybe there is interference between antenna and power
supply line. Please try to separate them in a longer
distance.
Maybe the shielded-layer of signal wire is not connected
properly to the connector.
There appear streaks or light color
Check if interfered by other equipment and if interfered
on the screen
possibly by the equipment like transmitting antenna,
non-professional radio station and cellular phone.
1.2 TV set:
Symptoms
Unable to switch the power on
No picture and sound
Deterioration of color phase or
color tone
Screen position or size is not
proper
Picture is twisted and deformed
Picture color changed or colorless
Possible cause
Check to see if the power plug has been inserted
properly into the socket.
Check to see if the power supply of liquid crystal TV has
been switched on. (As can be indicated by the red LED
at the front of the TV set)
See if it’s receiving the signal that is transmitted from
other source than the station
Check if it’s connected to the wrong terminal or if the
input mode is correct.
Check if the signal cable connection between video
frequency source and the liquid crystal TV set is correct.
Check if all the picture setups have been corrected.
Check is the screen position and size is correctly set up.
Check to see if the picture-frame ratio is properly set up.
Check the “Component” or “RGB” settings of the liquid
19
Picture too bright and there is
distortion in the brightest area
Picture is whitish or too bright in
the darkest area of the picture
No picture or signal produced from
the displayer if “XXX in search”
appears.
There appears an indication “outside the receivable scope)
Remote control cannot work
properly

Check if it’s connected to the proper terminal or if the
input mode is correct.
Check if the TV set can receive input signal. The signal is
not correctly identified and VGA format is beyond the
specified scope.
Check if the batteries are installed in the reverse order.
Check if the battery is effective.
Check the distance or angle from the monitor.
Check if there is any obstruct between the remote control
and the TV set.
Check if the remote control signal- receiving window is
exposed to strong fluorescence.
Check if the antenna cable is correctly connected, or if it
has received the video signal correctly.
Check if the antenna cable is correctly connected.
Of if it has received the right video signal.
Check if the “mute” audio frequency setting is selected.
Check if the sound volume is set to minimum.
Make sure the earphone is not connected.
Check if the cable connection is loose.
When being played or in pause VHS picture search tape

Assembling the stand and removing the stand column(Option)
If the stand is provided, please read these instructions thoroughly before attempting this installation.
You must install your TV into the stand in order for it to stand upright on a cabinet or other flat surface. If you intend
to mount your TV on a wall or other vertical surface, you must remove the stand column.
Cautions:
Make sure that you handle your TV very carefully when attempting assembly or removal of the stand. If you are not
sure of your ability to do this, or of your ability to use the tools necessary to complete this job, refer to a
professional installer or service personnel. The manufacturer is not responsible for any damages or injuries that
occur due to mishandling or improper assembly.
When using a table or bench as an aid to assembly, make sure that you put down a soft cushion or covering to
prevent accidental scratching or damage to your TV's finish.
The speaker is not intended to support the weight of your TV. Do not move or handle your TV by the speaker.
This can cause damage to your TV that is not covered by the manufacturer's warranty.
Before attempting assembly or removal of the stand, unplug the AC power cord.
To install the stand:
1. Remove the stand from the box and place it on a table or bench.
You must pay attention to the direction of the stand. The wide portion of the stand should go towards
the front of the TV.
2. Lay your TV flat (screen down) on the edge of a table or bench. Make sure that you put down a soft
cushion or cloth so that your TV is not scratched.
3. Insert the stand column into the stand socket, move the column steadily until the Locators on the
column align with the locating grooves on the stand. And align the holes in the stand with the holes in
the stand column, then secure the stand to the column with four M5 screws(provided).
