Product safety notice
Many electrical and mechanical parts in this product include specific, safety related characteristics. These
characteristics may not be immediately obvious by visual inspection and the protection these components
offer can not necessarily be obtained using replacement components with the same voltage or power ratings.

Replacement parts with specific safety characteristics are identified in this manual and its supplements.
Electrical components having such features are identified by shading on the schematic diagram and in the
parts list. Before replacing components, read the parts list in this manual thoroughly.

The use of substitute parts which do not have the same safety characteristics as those indicated in the parts
list may cause electrical shock, fire, x-ray emissions, or other hazards.


Service notes
1. When replacing circuit boards or components, clamp the lead wires to the terminals before soldering.
2. When replacing a high power resistor (oxide metal film resistor) on a circuit board, keep the resistor at
least 10 mm (0.5-inch) from the circuit board.
3. Keep leads and wires away from high voltage and high temperature components.
4. If any fuse in the product is blown, replace it only with the correct fuse specified in the parts list.


Handling of broken glass and liquid crystal leakage
If the LCD is damaged, liquid crystal leakage may occur and the glass may shatter into small pieces. Do not
touch the broken glass or liquid crystal which is toxic. In addition to possible cuts resulting from broken
glass, toxic leakage may cause skin irritation or poisoning. If liquid crystal enters your eyes or mouth, you
should immediately rinse with clean water and consult a doctor.


Important safety information
1. Read all these instructions.
2. Save these instructions for later use.
3. Unplug this television set from the wall outlet before cleaning.
4. Do not use accessories not recommended in the user manual as they may damage the product.
5. Do not use this product in wet locations such as near a bathtub, washbowl, kitchen sink, laundry tub,
swimming pool, or in a wet basement.

6. Do not place this product on an unstable cart, stand, or table. The television receiver may fall and cause
serious injury as well as possibly damaging the product. Use only with a cart or stand recommended
by the manufacturer or sold with the product. Wall or shelf mounting should follow manufacturer's
instructions and only use a mounting kit as recommended by the manufacturer.
7. Blocking the ventilation holes can cause overheating and fire. Take care not to block any ventilation holes
when siting the television close to walls or other objects. Never install this product in a closed cabinet or
bookcase unless sufficient ventilation is provided.
8. This television should be operated using only the type of power source indicated on the label and in the
user manual. If you are unsure what your home power supply is, you should consult the Power Company
or talk to your television dealer.
9. This television is equipped with a plug designed to fit only one way in the power socket. The earth pin is
an important safety feature of the plug. If the plug does not fit your outlets or your outlets do not include
a hole for the earth pin, you should consult a qualified electrician about replacing the socket.
10. Do not rest anything on the power cord and do not allow the power cord to lie in a position where it is
likely to be stepped on or tripped over.
11. Follow all warnings and instructions marked on the television receiver.
12. During thunderstorms and when the television is unused for extended periods of time, you should
unplug the power cord from the outlet and disconnect the antenna.
13. External antenna systems should be sited away from overhead power lines and away from electrical
circuits. Extreme caution should be exercised when erecting an outside antenna. Touching overhead
power cables can be fatal.
14. Do not overload power outlets or extension cords as fire or electric shock can result.
15. Never push anything into the television through the ventilation slots as they may come into contact with
high voltage elements of the device and cause electric shock or fire. Take care never to spill liquids into
the product.
16. Servicing of this product should only be carried out by qualified service technicians.
17. Unplug this product from the power source and consult a qualified service technician in the following
cases:
· The power cord is damaged or frayed.
· Liquid is spilled into the television.
· The television is exposed to rain or water.
· The television does not operate as the user manual describes. In this case, use only the controls
covered by the operating instructions. Improper adjustment of this equipment using controls not
covered in the user manual may result in damage to the product that may require extensive work
by qualified technicians to rectify.
· The television or cabinet is damaged.
· The television shows a change in performance that indicates a need for servicing.
18. When replacement parts are used, ensure that the technician uses only parts recommended by the
manufacturer. Unauthorised replacement parts may cause a fire or electric shock.
19. After servicing, ensure that the technician performs routine safety checks to determine whether the
television is in a safe operating condition.
20. When moving this equipment, care should be taken to prevent damage due to dropping, falling or
impact.

Power Circuit:
Exchanged Power Model provides this machine 3 batch power: +12V, +5V and +24V. +5V is Stand-By power,
provides every circuit in main board needed power with +12V.+24 is back light power.

A.Cold-Opening Mode
·Exchanged Power Model (+12V, +5V), via J17 jack transmits voltage to digital main board.
·When connect with AC220V, exchanged power produces +5V voltage immediately (circuit mark 5V_SB)
and provides CPU U83 the needed stand-by voltage to turn on the machine.
·This machine is in Stand-By Mode now.

B.Stand-By Mode(+5V)
·In Stand-By Mode, Exchanged Power Model provides +5V voltage (circuit mark 5V_SB) and provides
the needed power to CPU U83 PIC 16F505.
·When this machine is in Stand-By mode, only U83 PIC16F505 keeps working, so the system can assure
the consumption power is < 1.5W in Stand-by Mode.
·The Block Diagram 1 shows Stand-By Mode.
C.Power ON Mode(+5V ,+12V)
·When the system receives the start order by Power Key of the remote control or Power ON/OFF of the
control panel, it will process the following action.
·The system hands over CPU's masterdom from CPU U83CPU to U29 M30620 .
·When exchanged power receives the start order by CPU U83, (signal mark POWER_ON), via Q33
MMBT3904 to control Exchanged Power Model provides +12V voltage (signal mark VCC_12V). Every
batches of digital board circuit would be able to process Power ON procedure.
·After every batches of digital board process Power ON procedure,U29 M30620 via BKLT_CNTL to
control circuit and light the back light.
·The Block Diagram 2 shows the voltage of Power ON Mode and IC.

Reassembly
Reassembly is the reverse of the disassembly procedure. When reassembling the LCD TV, note the following
points:
The LCD panel is delicate and care should be taken to ensure that it is not scratched when removed.
Do not expose the LCD panel to dust or sharp objects.
