Product safety notice
Many electrical and mechanical parts in this product include specic, 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 identied 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 specied 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.

Switching power Model provide this machine 3 batch power: +12V, +5V and +24V. +5V
is Stand-By power, with +12V provide every circuits in main board needed power .+24 is
back light power.
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.

• U25 is 16Mbit Flash Rom. Boot code and Appcode are store in U25. The program came
be upgraded via VGA jack.
• U21 is 64Kbits EEPROM and allow repeat record 100000 times. Main function is store
the adjustment record of machine and menu setting record.
• U27, U28 are 128Mbit SDRAM.Main function is store DATA.EX. Deinterlace, 3DComb
scaler.
• CPU control ow path:
a:CPU reading the program of U25 Flash Rom after turn on the machine.
b:CPU setting register record of IC to be the unofcal decision record of system program.
c:CPU link up with IC (tuner)
