Safety Precaution
PRECAUTIONS DURING
SERVICING
1. In addition to safety, other parts and
assemblies are specified for conformance with
such regulations as those applying to spurious
radiation. These must also be replaced only
with specified replacements.
Examples: RF converters, tuner units, antenna
selection switches, RF cables, noise-blocking
capacitors, noise-blocking filters, etc.
2. Use specified internal Wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
3. Use specified insulating materials for hazardous
live parts. Note especially:
1) Insulating Tape
2) PVC tubing
3) Spacers (insulating barriers)
4) Insulating sheets for transistors
5) Plastic screws for fixing micro switches
4. When replacing AC primary side components
(transformers, power cords, noise blocking
capacitors, etc.), wrap ends of wires securely
about the terminals before soldering.
5. Make sure that wires do not contact heat
generating parts (heat sinks, oxide metal film
resistors, fusible resistors, etc.)
6. Check if replaced wires do not contact sharply
edged or pointed parts.
7. Make sure that foreign objects (screws, solder
droplets, etc.) do not remain inside the set.
The lightning flash with arrowhead symbol,
within an equilateral triangle, is intended to
alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclo
sure that may be of sufficient magnitude to
constitute a risk of electric shock to persons.
The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.
CAUTION: TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT REMOVE COVER
(OR BACK). NO USER-SERVICEABLE PARTS
INSIDE. REFER SERVICING TO QUALIFIED
SERVICE PERSONNEL ONLY.
CAUTION

MAKE YOUR CONTRIBUTION
TO PROTECT THE
ENVIRONMENT
Used batteries with the ISO symbol
for recycling as well as small accumulators
(rechargeable batteries), mini-batteries (cells) and
starter batteries should not be thrown into the
garbage can.
Please leave them at an appropriate depot.
WARNING:
Before servicing this TV receiver, read the
SAFETY INSTRUCTION and PRODUCT
SAFETY NOTICE.
SAFETY INSTRUCTION
The service should not be attempted by anyone
unfamiliar with the necessary instructions on this
apparatus. The following are the necessary
instructions to be observed before servicing.
1. An isolation transformer should be connected in
the power line between the receiver and the
AC line when a service is performed on the
primary of the converter transformer of the set.
2. Comply with all caution and safety related
provided on the back of the cabinet, inside the
cabinet, on the chassis or picture tube.
3. To avoid a shock hazard, always discharge the
picture tube's anode to the chassis ground
before removing the anode cap.
4. Completely discharge the high potential voltage
of the picture tube before handling. The picture
tube is a vacuum and if broken, the glass will
explode.

PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this
apparatus have special safety-related
characteristics.
These characteristics are offer passed
unnoticed by visual spection and the protection
afforded by them cannot necessarily be obtained
by using replacement components rates for a
higher voltage, wattage, etc.
The replacement parts which have these
special safety characteristics are identified by
marks on the schematic diagram and on the parts
list.
Before replacing any of these components,
read the parts list in this manual carefully. The
use of substitute replacement parts which do not
have the same safety characteristics as specified
in the parts list may create shock, fire, or other
hazards.
9. Must be sure that the ground wire of the AC
inlet is connected with the ground of the
apparatus properly.
5. When replacing a MAIN PCB in the cabinet,
always be certain that all protective are
installed properly such as control knobs,
adjustment covers or shields, barriers, isolation
resistor networks etc.
6. When servicing is required, observe the original
lead dressing. Extra precaution should be given
to assure correct lead dressing in the high
voltage area.
7. Keep wires away from high voltage or high
tempera ture components.
8. Before returning the set to the customer,
always perform an AC leakage current check
on the exposed metallic parts of the cabinet,
such as antennas, terminals, screwheads,metal
overlay, control shafts, etc., to be sure the set
is safe to operate without danger of electrical
shock. Plug the AC line cord directly to the
AC outlet (do not use a line isolation
transformer during this check). Use an AC
voltmeter having 5K ohms volt sensitivity or
more in the following manner.
Connect a 1.5K ohm 10 watt resistor paralleled
by a 0.15μF AC type capacitor, between a
good earth ground (water pipe, conductor etc.,)
and the exposed metallic parts, one at a time.
Measure the AC voltage across the combination
of the 1.5K ohm resistor and 0.15 uF
capacitor. Reverse the AC plug at the AC
outlet and repeat the AC voltage measurements
for each exposed metallic part.
The measured voltage must not exceed 0.3V
RMS.
This corresponds to 0.5mA AC. Any value
exceeding this limit constitutes a potential
shock hazard and must be corrected
immediately.
The resistance measurement should be done
between accessible exposed metal parts and
power cord plug prongs with the power switch
"ON". The resistance should be more than
6M ohms.
Good earth ground
such as the water
pipe, conductor,
etc.
Place this probe
on each exposed
metallic part

Attention:
Motionless picture might cause permanent destruction to the display.
Be sure not to display motionless picture on the LCD TV for more than
2 hours, because it would cause picture remnants to appear, which is
called "screen burns". To avoid such picture remnants, please decrease
the "contrast" and "brightness" of the display when displaying motionless
picture.
While watching TV program in 4:3 size mode for a long time, there would
be traces on the edge of the screen's left, right and center parts because
of different transmition of the light on the screen.Similar impact on the
screen will occur when playing DVD or connecting games control. Products
destroyed by these reasons can't be guaranteed for maintenance.
It might cause picture remnants to display electronic games and motionless
picture of PC more than a period of time.To avoid such effect, please
decrease the "contrast" and "brightness" when displaying motionless
picture.

PCB failure analysis
1. CONTROL:
a. Abnormal noise on screen.
b. No picture.
2. MAIN (VIDEO):
a. Lacking color, Bad color scale.
b. No voice.
c. No picture but with signals output, OSD and back light.
d. Abnormal noise on screen.
3. POWER:
No picture, no power output.
Basic operation of LCD-TV
1. After turning on power switch, power board sends 5Vst-by Volt to Micro
Processor IC waiting for ON signals from Key Switch or Remote Receiver.
2. When the ON signal from Key Switch or Remote Receiver is detected, Micro
Processor will send ON Control signals to Power. Then Power sends (5Vsc,
12Vsc, 24V and RLY ON, Vs ON) to PCBs working. This time VIF will send
signals to display back light, OSD on the panel and start to search available
signal sources. If the audio signals input, them will be amplified by Audio AMP
and transmitted to Speakers.
3. If some abnormal signals are detected (for example: over volts, over current,
over temperature and under volts), the system will be shut down by Power off.

/&'EDVLFGLVSOD\WKHRU\
When an electrical field is applied to the LC planes, the LC molecules re-align
themselves so that they are parallel to the electrical field. This electrical process
is known as twisted nematic field effect or TNFE. In this alignment, polarized
light is not twisted as it passes through the LC material (see Diagram 3A and
3B). If the front polarizer is oriented perpendicular to the rear polarizer, light will
pass through the energized display but will be blocked by the rear polarizer. An
LCD in this form is acting as a light shutter.
Displays with variable characters are created by selectively etching away the
conductive surface that was originally deposited on the glass. Etched areas
become the display’s background; unetched areas become the display’s
characters.
