High Performance Split carrier IF receiving module unit

TIF module (H001) is consisting of the Tuner and IF blocks.

SIF signal corresponding to the receiving RF system is demodulated in MSP (Multi Sound Processor)

in IC600.

RF system switching is performed by controlling the switching circuit in IC TDA9886 on TIF module

through IIC Bus line.

When receiving L-system VHF Low Band signal, IF frequency is switched accordingly.

3-3 Signal Process circuit

a）Video Signal process

Composite Video Signal input

The input signal is converted to the colour differential signal at the digital colour decoder through A/D converter

and 3 YC separation circuit. When the composite signal is input through S-terminal, it is directly fed into the

digital colour decoder to convert to the colour differential signal.

In case of component signal input, it is fed to the digital colour decoder through A/D converter.

The digital input signal is directly fed into the MUX circuit.

b）Scaler Process

This processor performs the progressive signal conversion for 480i60 and 1080i60 interlace signal, the Horizontal

and Vertical pixel conversion to ultimate to the display panel, the scaling conversion according to the picture size

３－２

and the insertion of OSD signal from SEINE.

IC701 and IC702 (DDR-SDRAM) are for the progressive conversion and the scaling process.

c) Back End Processor

This functions various picture controls such as Contrast, Colour, TINT, Sharpness and Black level and also for

Dynamic gamma collection, colour management, colour matrix and RGB gamma collection.

d) LVDS

The interface signal LVDS generated in IC400 and IC700 is fed to the panel.

3-4 Microprocessor control process

There are two microprocessors of IC400 (Stand-by microprocessor) and IC 700 (FLI8532).

The Firmware in Stand-by microprocessor IC400 is possible to rewriting.

The program for IC700 is stored in IC404 Flash Memory and it is possible to rewriting.

IC 700 controls IC400 through IIC BUS line.

To control power On or Off is shown below. I/O expansion on IC700 is used for LED control, S1/S2 detection and

so on by using I/O expander.

The microprocessor in IC700 is controlled by Seine microprocessor via UART and also it controls IC700 itself,

multiplex sound IC, analogue tuner and others.

Chapter ７. Power Circuit

７－1 Outline

The power circuit is consisting of several blocks as shown in Block diagram. It is mainly consisting of AC

INPUT Unit, Main Power Unit, Sub-Power Unit and regulators for signal process.

①ACINPUTUnit

It is consisting of line filter (T801and T802), Reactors(L801 and L80), rectifying stuck diodes(D801 and

DE01), AC relay (SR81) and others to rectify the AC input.

②MAIN POWER Unit

It generates +24V for LCD panel and +30V for Audio output with using Q801(STR-Z4369).

While the stand-by mode, the MAIN POWER Unit is turned off by SR81 off.(Open)

③SUB-POWER Unit

It generates +40V, +18V, +6.5V1 and +6.5V2 for stand-by microprocessor, Signal Unit, Tuner and

others. New device STR-W6765 is employed as QE01.

④Regulator for Signal process

The Regulators QE71, QE40 and QE40 are located in the MAIN POWER Unit.

・ Regulator : ＱＥ７1 (Device Name: CE-1050)

７－４．SUB-POWER Unit

The SUB-POWER Unit is for Stand-by microprocessor, Signal Unit, Tuner circuit and stand-by power source.

The quasi-resonating type is employed with QE01. The converter transformer TE62 has 4 output lines.

The block diagram and pin configuration of QE01 (STR-W6765) are shown in Fig 7-5 and Fig 7-7.

QE01 (STR-W6765) is oscillating as quasi-resonating mode at the normal mode and it adopts the bottom skip

function to improve the efficiency when the power consumption is low or middle ranges. When the power

consumption is lowest, then it oscillates as BURST mode (interval oscillation) to save the power consumption

while stand-by mode.

At the starting period, AC current is charged in CE16 through DE02 and DE03. When the charged voltage at

CE16 reaches 18.2V (typ), then the inner circuit of QE01 will function.

Once starting the function, Vcc is applied through TE62 and when Vcc is below 9.7V (typ) , the function will

be quit and reset before starting. The power load is the same in stand-by or normal operation mode.

The reference voltage at the secondary circuit of SUB-POWER Unit is set 18V and it is controlled through

the loop circuit consisting of Error Amplifier QE83, photo coupler QE26 and QE01.

The variation of 18V is detected at QE83 and the detected current is fed back to pin#6 of QE01 though QE26

and then QE01 changes the switching frequency and pulse duty accordingly to obtain the stable 18V.

In case of feedback loop malfunction such as QE26 open circuit, QE01 detects the low output and functions

to increase the output, then all line outputs of TE62 increase. When Vcc is over 27.7V (typ), the over voltage

protection in QE01 stops the function and this condition is latched. To release this, turn off AC power and on to

reduce Vcc below 7.2V (typ).

The same function is carried out when the secondary circuit load is overloaded.

When the power consumption is lowest, then QE01 turns into BURST mode automatically and the oscillation is

interval mode.

IC872 Circuitry

IC872 is DC-DC converter to generate 5V2 that drives CORTEZ, Tuner and other analog circuits at 18V input

and is controlled by POWER_TV ON/OFF signal through Q877 and Q878.

QE71, QE76, QE77 and IC872 are the same type of DC-DC converter module. Type name CE-1050 or

CE-1047 differs packaging but is functionally the same.

The output voltage is determined the resistor value between pin 8 and GND. When pin 8 is open circuit, the

output voltage is 5V.

The output can be obtained by applying over 3V or open circuit at pin 5 and it turns off when the applied voltage

at pin 5 is below 0.4V.

The over current protector is incorporated and it works to reduce the output voltage when the load current is

over 3.5A (typ) and also it is automatically reset when the load current is below 1A.

QE40 Circuitry

QE40 is a DC-DC converter HIC for the stand-by microprocessor and composes the DC-DC converter circuit

with DE50, LE53 and others. The output voltage is 5V1 at 18V input.

The basic function is the same as SI-80 series.

７－６． Protection circuit

The protection circuit is set at 24V and LCD_Vcc lines.

When this functions, the main power is set to OFF by turning SR-81 off with setting POWER_SIG forced LOW.

If the POWER_SIG is detected as LOW while normal operation, the microprocessor recognizes the protection

mode and set TV into the stand-by mode.

PROTECT signal turns Q853, Q854 and Q855 on, and as a result SR81 turns off due to Q851 and Q852 turns

off. Q853 and Q854 keep the protection mode and the POWER LED flashes to indicate the protection mode.

To release the protection mode, pull AC cable out and connect it again.
