Product safety notice
Many electrical and mechanical parts in this product include specic, 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.
Electrical components having such features are identied 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, re, 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 lm 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 specied 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.
II
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 re. 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 sufcient ventilation is provided.
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 t only one way in the power socket. The earth pin is an important safety feature of the plug. If the plug does not t your outlets or your outlets do not include a hole for the earth pin, you should consult a qualied 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 re 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 re. Take care never to spill liquids into
the product.
16. Servicing of this product should only be carried out by qualied service technicians.
17. Unplug this product from the power source and consult a qualied 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 qualied 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 re 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.

A.Cold-Opening Mode
•When connect with AC, switching power produce +5V voltage immediately
(circuit mark Vsub) and provide U1(PW106B) the needed stand-by voltage to turn on the machine
•This machine is in Stand-By Mode now.
B.Stand-By Mode(+5V)
•W h en t hi s ma c hi ne is in St an d- B y mo de , onl y U1 (P W 10 6B ) and
U25(EN29LV160) keep workings, U1 enter power saving mode, so the system can assure the consumption power is < 2.5W in Stand-by Mode.
C.Power ON Mode
•When the system receives the start order by Power Key of the remote control
or Power ON/OFF of the control panel, it enter power ON mode.
•When switching power receives the start order by U1, via Q23 to control
Switching power Model provides +12V and +24V voltage . .
•After every batches of digital board process Power ON procedure,U1 via BKLTPWER(=H) to start Inventer and light the back light.
•The Block Diagram shows the voltage of Power ON Mode and IC.

Antenna Circuit:
• Tuner FQ1216 receive the signal come from CATV or antenna RF PAL/SECAM signal
and demodulate image composite signal (signal mark TV 1) and audio medium frequency signal (signal mark SIF1).
• Image composite signal (signal mark TV 1)
• Via Q6 Video buffer(signal mark TV1_EX) than enter U37 Scaler IC EX-52 CVBS1 in-
put jack (Pin242) directly. Switches with other input signals in inner switch circuit.
• Other one via Q9 buffer (signal mark TV1_SW) enter U22 SCRAT SWITCH IC
CXA2125 TV_CVBS VIN_15 input jack (Pin23) and switch with other input signals to pro­cess POP/PIP signals selection .
• Audio medium frequency signal (signal mark TVAF1), transmits to U48 MSP3410/
MSP3411 SOUND PROCESSOR PIN50 to demodulate audio IF and stereo. Than switches signal source with other Audio Source (PC AUDIO, U22 SCART SWITCH IC CX-
