SERVICE MANUAL FOR M113 CHASSIS

PART I. Servicing Precautions

When working, the unit is with ultra high voltage about 25KV inside. So, to avoid the risk of electric shock, be careful to adjust the chassis!

1. Only qualified personnel should perform service procedures.

2. All specification must be met over line voltage ranger of 110V AC to 240V AC 50Hz/60Hz.

3. Do not operate in WET/DAMP conditions.

4. Portions of the power supply board are hot ground. The remaining boards are cold ground.

5. Discharge of CRT anode should be done only to CRT ground strap.

6. When fuse blow, ensure to replace a fuse with the same type and specification.

7. Keep the wires away from the components with high temperature or high voltage.

8. When replacing the resister with high power, keep it over the PCB about 10mm.

9. The CRT anode high voltage has been adjusted and set in the factory. When repairing the chassis, do not make the high voltage exceed 27.5KV (The beam current is 0uA). Generally, the high voltage is set on

25.5KV±1.5KV (The beam current is 700uA). * The values of parameters above are for information only.

10. Before return the fixed unit, do check all the covering of wires to ensure that not fold or not short with any metal components. Check the entire protection units, such as control knobs, rear cabinet & front panel, insulation resister & capacitor, mechanical insulators and so on.

11. There are some mechanical and electrical parts associating with safety (EMC) features (Generally related to high voltage or high temperature or electric shock), these features cannot be found out from the outside. When replace these components, perhaps the voltage and power suit the requirements, but efficient X-ray protection may not be provided. All these components are marked with Ì in the schematic diagram. When replace these, you’d better look up the components listed in this manual. If the component you replaced not has the same safety (EMC) performance, harmful X-ray may be produced.

1.RF、IF AMP

The tuner receives, selects and amplifies RF signal, frequency mixes with local oscillate source, gets

38.0MHz&38.9MHz IF signal via C107 to Q101.After Q101 amplifing about 20dB,the PIF(Picture IF) and SIF(Sound IF) are separated. Having passed sawfilter, PIF signal sent to TMPA8809 in pin 41,42.The IF signal pass the video detect circuit to generate CVBS signal. Then the processor deals the signal with luminance and chroma separation. The processor also deals the chroma siganl with integrated chroma BPFs, PAL/NTSC demodulation and deals luminance signal with integrated chroma traps, black strech, Y-gamma, so that the resolution of picture details is improved and Y signal is well timed with chroma signal. The processor also deals the chroma signal with chroma sub-carrier recovery, color system recognition and color signal decoding, then output R\G\B to CRT board. Via three groups dual emitter amplifiers to drive KR\KG\KB. On the other hand, the processor separated by video detect circuit. Having passed the horizontal & vertical frequency dividing circuit, H&V OSC signal, which be generated by H-AFC&V-AFC, then output H&V signal which wave is sawtooth.

2.Channel Selection

The RF signal is converted into IF signal by the tuner. Then the IF signal cross the IF amplifier circuit(IF pre-amp) to get a gain about 15dB. By the coupling capacitance(C107) and the match resistance R107,the input resistance of the IF pre-amplifier match with the tuner. The signals pass a parallel connection circuit with voltage NFB, which the input and output impedance is lower, of wide dynamic rage.R106 is the NFB resistance, which is used to adjust the gain in the pass band. Having been amplified by the IF amplifier, the IF signal pass the IF sawfilter K3955K(and C109 is the coupling cap.).Than PIF signal been sent from pin 4,pin5 of sawfilter to pin 41,pin42 of super one chip(TMPA8809).The processor deal the PIF signal with IF

detection, PLL demodulation, IF AGC, AFC, video peak detection, and color system recognition ect, then output a AGC signal from pin43 to the tuner to adjust the input control IF detection.R228,C227,C226 makes up picture IF PLL circuit, which is used to control IF detection.IC101 output a TV signal from pin30,when pin30 level is high, TV-out signal is amplified by Q202,Q204,and Q203,Q205 is system switch which controlled by Q211,Q210.

Tuning control and band switch control circuits The processor output a tuning control signal from pin60.The control signal will pass Q004 and R/C network to be amplified and differential circuit, then added to VT terminal to provide all channels’ tuning voltage for the tuner to make the channel stable.

3.Vertical Output Section

TMPA8809 outputs vertical saw-tooth wave from pin 16. It come to pin1 of TDA8172 with DC coupling, and is amplified by inner difference amplifier. Pin7 of TDA8172 is the same phase input terminal. R302 and R303 are DC offset resistances. C304 is a filter capacitor. In application to M113, pin7 of TDA8172 is fixed as the DC amplify ref terminal. The amplified saw tooth-wave comes out from pin5 and make the deflect coil to generate the deflect current. R304 and C305 filtrate the inductive interference from the horizontal deflect coil. R310 and C309 are used to eliminate spurious oscillation generated by the deflect coil and distributed capacitance resonance. C308, R309, C307 and accessory circuit are in charge of draw AC saw tooth wave out at the deflect coil terminal connected with R303A, and feedback to the input terminal of TDA8172 (pin1) to correct the linearity of horizontal scan. C301 is a high frequency decoupling capacitor. D301 and C302 make up of a voltage pump up circuit. TDA8172 output a vertical kickback impulse from pin6 to locate the OSD characters.

4.Horizontal Output And FBT Section

The processor outputs horizontal drive impulse from pin 13(H-OUT). The drive impulse is done with voltage division by R201 and R401, and then comes to the base of the drive triode (Q401). C401 is used to eliminate the noise in the H drive impulse. T401 is a horizontal drive transformer. Q411 is a horizontal output triode with a damper inside. L412 is connected with the emitter of the horizontal output diode to eliminate the radiation and to improve the distortions at the cross of vertical and horizontal white lines. C412 and C413 are retrace capacitors and C414 is an s-correct capacitor. L413 is horizontal linear inductors. R441 is used to eliminate the parasitic oscillation caused by horizontal linear inductors. C421, R421 and D421 are used to correct the M-distortion in horizontal direction. The deflect coil and the horizontal output triode have some resistance R while they are ducting. The resistance R will cause the non-linear distortion, which means that the right direction scanning speed of the electron beam becomes slower, and the right of the raster is compressed to generate distortion. We use a horizontal linear adjuster to compensate this kind of distortion. We use L414 as the H linear adjuster in horizontal scanning section of M113 chassis. R419, which is parallel connected with L414, is a despiking resistance for preventing the oscillation by compensating inductor and the stray capacitance. The linear adjuster is a transductor coil with a magnetic core inside. If the current, which pass the linear adjuster coil, increase to a certain value, the magnetic core becomes saturated to decrease the inductance of the linear adjustment inductor. If the +B is steady, the increase speed of Iy is faster to compensate the reducing of deflecting current by the resistance R mention above. We can adjust the magnetic core to change the inductance of the linear compensate inductor to adjust the H linearity.

horizontal output circuit.

The EHT generation circuit The FBT supply the anode high voltage, focus voltage and screen voltage for M113 chassis. D441and C441 are in charge of regulating the primary impulse of the transformer to output a voltage of 200V for the video amplifiers. The ( 4 ) ~ ( 7 ) coils of the FBT supply the heater with power. To limit the beam current i n a safe range, we add a ABL(auto brightness limit) circuit in M113 chassis. When the beam current is higher than normal,Q451 which is a emitter follower strength conductivity, the emitter gets a lower negative voltage, so the collector of it follows a lower voltage, then gain of system brightness decreases, brightness decrease and beam current decreases.

Also the ABL control voltage is sampled from R426 to adjust & control EW-scan.

Extension distortion and compensation This kind of distortion is mainly caused by the structure of CRT. Due to the screen of SF CRT is not a pure flat screen, the distances from the deflecting center to the screen are not the same. The scanning speed of the electron beam is uniform. If the electron beam scannning the screen equally with the effect of ture linear sawtooth current, the E-W sides of the picture are stretched. That is the extension distortion. Usually, we add a S-correct capacitor in series with the deflecting coil to compensate this kind of distortion. The integral character of S-correct capacitor make the current waveform S shape. So the scanning speed of electron beam at the center of screen is faster than the one at the side. So this action can correct the extension distortion. C414 is a S-correct capacitor. The capacitance is inverse ratio with the correcting effection.

4 Ground This pin is the ground of the primary side of the SMPS.

A current detection and 120 A current detection. The 24 A level is used to detect the secondary reconfiguration status and the 120 A level to detect an Over Voltage status called Quick OVP. The Current Sense pin senses the voltage developed on the series resistor inserted in the source of the power MOSFET. When Isense reaches 1V, the Driver output (pin 5) is disabled. This is known as the Over Current Protection function. A 200 A current source is flowing out of the pin 3 during the start–up phase and during the switching phase in case of the Pulsed Mode of operation. A resistor can be inserted between the sense resistor and the pin 3, thus a programmable peak current detection can be performed during the SMPS stand–by mode.

A feedback current from the secondary side of the SMPS via the opto–coupler is injected into this pin. A resistor can be connected between this pin and GND to allow the programming of the Burst duty cycle during the Stand–by mode.

This pin is the positive supply of the IC. The driver output gets disabled when the

voltage becomes higher than 15V and the operating range is between 6.6V and 13V. An intermediate voltage level of 10V creates a disabling condition called Latched Off phase.

This pin can be directly connected to a 500V voltage source for start–up function of the IC. During the Start–up phase a 9 mA current source is internally delivered to the VCC pin 6 allowing a rapid charge of the VCC capacitor. As soon as the IC starts–up, this current source is disabled.

OPERATING DESCRIPTION

Regulation

The pin 3 senses the feedback current provided by the opto-coupler. During the switching phase the switch S2 is

closed and the shunt regulator is accessible by the pin 3. The shunt regulator voltage is typically 5V. The dynamic

resistance of the shunt regulator represented by the zener diode is 20 .

The gain of the Control input is given on Figure 10 which shows the duty cycle as a function of the current injected

into the pin 3.

The maximum current sense threshold is fixed at 1V. The peak

A 4KHz filter network is inserted

between the shunt regulator and the

PWM comparator to cancel the high

frequency residual noise.

The switch S3 is closed in Stand–by

mode during the Latched Off Phase

while the switch S2 remains open. (See

section PULSED MODE DUTY

CYCLE CONTROL).

The resistor Rdpulsed (Rduty cycle

burst) has no effect on the regulation

process. This resistor is used to

determine the burst duty cycle described in the chapter “Pulsed Duty Cycle Control” on page 8.

PWM Latch

The MC44608 works in voltage mode. The on–time is controlled by the PWM comparator that compares the

oscillator sawtooth with the regulation block output.

The PWM latch is initialized by the

oscillator and is reset by the PWM

comparator or by the current sense

comparator in case of an over current.

This configuration ensures that only a

single pulse appears at the circuit

output during an oscillator cycle.

Current Sense

The inductor current is converted to a

positive voltage by inserting a ground

reference sense resistor R

with the power switch.

The maximum current sense threshold is fixed at 1V. The peak

current is given by the following equation:

In stand–by mode, this current can be lowered as due to the activation of a 200 A current source:

required to sense the current.

Finally, this pin is used:

– as a protection against over currents (I

– as a reduction of the peak current during a Pulsed Mode switching phase.

The overcurrent propagation delay is reduced by producing a sharp output turn off (high slew rate).

This results in an abrupt output turn off in the event of an over current and in the majority of the pulsed mode

switching sequence.

output, which is disabled during the demagnetization phase.

The demagnetization pin is also used for the quick, programmable OVP. In fact, the demagnetization input current is

sensed so that the circuit output is latched off when this current is detected as higher than 120μA.

This function can be inhibited by grounding it but in this case, the quick and programmable OVP is also disabled.

Oscillator

The MC44608 contains a fixed frequency oscillator. It is built around a fixed value capacitor CT succesively charged

and discharged by two distinct current sources ICH and IDCH. The window comparator senses the CT voltage value

and activates the sources when the voltage is reaching the 2.4V/4V levels.

Demagnetization Section

The MC44608 demagnetization

detection consists of a

comparator designed to compare

CC winding voltage to a

the V

reference that is typically equal

to 50mV.

This reference is chosen low to

increase effectiveness of the

demagnetization detection even

during start–up.

A latch is incorporated to turn

the demagnetization block

output into a low level as soon

as a voltage less than 50 mV is

detected, and to keep it in this

state until a new pulse is

generated on the output. This

avoids any ringing on the input

signal which may alter the

demagnetization detection.

For a higher safety, the

demagnetization block output is

also directly connected to the

The complete demagnetization status

DMG is used to inhibit the recharge of the

CT capacitor.

Thus in case of incomplete transformer

demagnetization the next switching cycle is

postpone until the DMG signal appears. The

oscillator remains at 2.4V corresponding to

the sawtooth valley voltage. In this way the

SMPS is working in the so called SOPS

mode (Self Oscillating Power Supply). In

that case the effective switching frequency is

variable and no longer depends on the

oscillator timing but on the external working

conditions (Refer to DMG signal in the

Figure 5).

The OSC and Clock signals are provided according to the Figure 5. The Clock signals correspond to the CT capacitor

discharge. The bottom curve represents the current flowing in the sense resistor Rcs. It starts from zero and stops

when the sawtooth value is equal to the control voltage Vcont. In this way the SMPS is regulated with a voltage mode

control.

Overvoltage Protection

The MC44608 offers two OVP functions:

– a fixed function that detects when V

– a programmable function that uses the demag pin. The current flowing into the demag pin is mirrored and

compared to the reference current Iovp (120μA). Thus this OVP is quicker as it is not impacted by the V

and is called QOVP.

In both cases, once an OVP condition is detected, the output is latched off until a new circuit

avalanche breakdown. To help increase the application safety against high voltage spike on that pin it is possible to

insert a small wattage 1k series resistor between the Vin rail and pin 8.

The Figure 6 shows the V

during the switching phase. This case can be encountered in SMPS when the self supply through an auxiliary winding

is not present (strong overload on the SMPS output for example).

The Figure16 also depicts this working configuration.

In case of the hiccup mode, the duty cycle of the switching phase is in the range of 10%.

These 2 cases are corresponding to the signal labeled NOC in case of “No Over Current” and “OC” in case of Over

Current. So the effective working status at the end of the ON time memorized in LW corresponds to Q=1 for no over

current and Q=0 for over current.

This sequence is repeated during the Switching phase.

Several events can occur:

1. SMPS switch OFF

2. SMPS output overload

3. Transition from Normal to Pulsed Mode

4. Transition from Pulsed Mode to Normal Mode

1. SMPS SWITCH OFF

When the mains is switched OFF, so long as the bulk electrolithic bulk capacitor provides energy to the SMPS, the

controller remains in the switching phase. Then the peak current reaches its maximum peak value, the switching

frequency decreases and all the secondary voltages are reduced. The V

to 10V, the SMPS stops working.

2. Overload

In the hiccup mode the 3 distinct phases are described as follows (refer to Figure 6):

The SWITCHING PHASE: The SMPS output is low and the regulation block reacts by increasing the ON time

(dmax = 80%). The OC is reached at the end of every switching cycle. The LW latch (Figure 7) is reset before the

VPWM signal appears. The SMPS output voltage is low. The VCC voltage cannot be maintained at a normal level as

CC voltage is also reduced. When VCC is equal

nominal / Vout short–circuit). Consequently the V

V

CC capacitor value together with the ICC working consumption (3.2mA) according to the equation 2. When VCC

crosses 10V the WORKING PHASE gets terminated. The LW latch remains in the reset status.

The LATCHED–OFF PHASE: The V

CC capacitor voltage continues to drop. When it reaches 6.5V this phase is

terminated. Its duration is governed by equation 3.

The START–UP PHASE is reinitiated. The high voltage start–up current source (–I

MODE latch is reset. The V

CC voltage ramps up according to the equation 1. When it reaches 13V, the IC enters into

the SWITCHING PHASE.

The NEXT SWITCHING PHASE: The high voltage current source is inhibited, the MODE latch (Q=0) activates the

NORMAL mode of operation. Figure 2 shows that no current is injected out pin 2.

The over current sense level corresponds to 1V.

As long as the overload is present, this sequence repeats. The SWITCHING PHASE duty cycle is in the range of

10%.

3. Transition from Normal to Pulsed Mode

In this sequence the secondary side is reconfigured (refer to the typical application schematic on page 13). The high

voltage output value becomes lower than the NORMAL mode regulated value. The TL431 shunt regulator is fully

OFF. In the SMPS stand–by mode all the SMPS outputs are lowered except for the low voltage output that supply the

wake–up circuit located at the isolated side of the power supply. In that mode the secondary regulation is performed

by the zener diode connected in parallel to the TL431.

The secondary reconfiguration status can be detected on the SMPS primary side by measuring the voltage level

present on the auxiliary winding Laux. (Refer to the Demagnetization Section). In the reconfigured status, the Laux

voltage is also reduced. The V

CC self–powering is no longer possible thus the SMPS enters in a hiccup mode similar

to the one described under the Overload condition.

In the SMPS stand–by mode the 3 distinct phases are:

The SWITCHING PHASE: Similar to the Overload mode. The current sense clamping level is reduced according to

the equation of the current sense section, page 5. The C.S. clamping level depends on the power to be delivered to the

load during the SMPS stand–by mode. Every switching sequence ON/OFF is terminated by an OC as long as the

secondary Zener diode voltage has not been reached. When the Zener voltage is reached the ON cycle is terminated

by a true PWM action. The proper SWITCHING PHASE termination must correspond to a NOC condition. The LW

latch stores this NOC status.

The LATCHED OFF PHASE: The MODE latch is set.

The START–UP PHASE is similar to the Overload Mode. The MODE latch remains in its set status (Q=1).

The SWITCHING PHASE: The Stand–by signal is validated and the 200μA is sourced out of the Current Sense

pin 2.

4. Transition from Stand–by to Normal

The secondary reconfiguration is removed. The regulation on the low voltage secondary rail can no longer be

achieved, thus at the end of the SWITCHING PHASE, no PWM condition can be encountered. The LW latch is reset.

At the next WORKING PHASE a NORMAL mode status takes place.

In order to become independent of the recovery time SWITCHING PHASE constant on the secondary side of the

Pulsed Mode Duty Cycle Control

During the sleep mode of the SMPS the switch S3 is closed and the control input pin 3 is connected to

source thru a 500Ωresistor. The discharge rate of the V

CC capacitor is given by ICC–latch (device consumption during

the LATCHED OFF phase) in addition to the current drawn out of the pin 3. Connecting a resistor between the Pin 3

Equations 1 through 8 define and predict the effective behavior during the PULSED MODE operation. The equations

6, 7, and 8 contain K, Y, and D factors. These factors are combinations of measured parameters. They appear in the

parameter section “K factors for pulsed mode operation” page 4. In equations 3 through 8 the pin 3 current is the

output current on pin TAGC (open-collector output). The tuner AGC takeover point level is set at pin TOP. This

allows the tuner to be matched to the SAW filter in order to achieve the optimum IF input level.

Frequency detector and phase detector

The VIF amplifier output signal is fed into a frequency detector and into a phase detector. During acquisition the

frequency detector produces a DC current proportional to the frequency difference between the input and the VCO

signal. After frequency lock-in the phase detector produces a DC current proportional to the phase difference between

the VCO and the input signal. The DC current of

either frequency detector or phase detector is converted into a DC

voltage via the loop filter which controls the VCO frequency.

Video demodulator

The true synchronous video demodulator is realized by a linear multiplier which is designed for low distortion and

wide bandwidth. The vision IF input signal is multiplied with the ‘in phase’ component of the VCO output. The

demodulator output signal is fed via an integrated low-pass filter (f

harmonics to the video amplifier.

TCL M113 Chassis Service Manual

The VCO operates with a symmetrically connected reference LC circuit, operating at the double vision carrier

frequency. Frequency control is performed by an internal variable capacitor diode.

The voltage to set the VCO frequency to the actual double vision carrier frequency is also amplified and converted

for the AFC output current.

The VCO signal is divided-by-2 with a Travelling Wave Divider (TWD) which generates two differential output

signals with a 90 degree phase difference independent of the frequency.

Video amplifier

The composite video amplifier is a wide bandwidth operational amplifier with internal feedback. A nominal positive

video signal of 1 V (p-p) is present at pin VSO.

Buffer amplifier and noise clipper

The input impedance of the 7 dB wideband CVBS buffer amplifier (with internal feedback) is suitable for ceramic

sound trap filters. Pin CVBS provides a positive video signal of 2 V (p-p). Noise clipping is provided internally.

Sound demodulation

L

IMITER AMPLIFIER

The FM sound intercarrier signal is fed to pin SI and through a limiter amplifier before it is demodulated. The result

is high sensitivity and AM suppression. The limiter amplifier consists of 7 stages which areinternally AC-coupled in

order to minimizing the DC offset.

FM-PLL DETECTOR

The FM-PLL demodulator consists of an RC oscillator, loop filter and phase detector. The oscillator frequency is

locked on the FM intercarrier signal from the limiter amplifier. As a result of this locking, the RC oscillator is

frequency modulated. The modulating voltage (AF signal) is used to control the oscillator frequency. By this, the

FM-PLL operates as an FM demodulator.

AF AMPLIFIER

The audio frequency amplifier with internal feedback is designed for high gain and high common-mode rejection.

The low-level AF signal output from the FM-PLL demodulator is amplified and buffered in a low-ohmic audio

output stage. An external decoupling capacitor CDAF removes the DC voltage from the audio amplifier input.

By using the sound mute switch (pin MUTE) the AF amplifier is set in the mute state.

FUNCTIONAL DESCRIPTION Description of the demodulator and decoder section

1. SIF INPUTS

Two inputs are provided, pin SIF1 and pin SIF2. For higher SIF signal levels the

SIF input can be attenuated with an internal switchable 10 dB resistor divider.

As no specific filters are integrated, both inputs have the same specification

giving flexibility in application. The selected signal is passed through

an AGC circuit and then digitized by an 8-bit ADC operating at 24.576 MHz.

2. AGC

The gain of the AGC amplifier is controlled from the ADC output by means of

a digital control loop employing hysteresis. The AGC has a fast attack behaviour

to prevent ADC overloads, and a slow decay behaviour to prevent AGC oscillations.

For AM demodulation the AGC must be switched off. When switched off, the

control loop is reset and fixed gain settings can be chosen. The AGC can be

controlled via the I

3. MIXER

The digitized input signal is fed to the mixers, which mix one or both input sound

C-bus.

carriers down to zero IF. A 24-bit control word for each carrier sets the required frequency. Access to the mixer

control word registers is via the I

programs, a feedback signal is added to the control word of the second carrier mixer to establish a carrier-frequency

loop.

4.FM AND AM

DEMODULATION

An FM or AM input signal is fed through a switchable band-limiting filter into a demodulator that can be used for

either FM or AM demodulation. Apart from the standard (fixed) de-emphasis characteristic, an adaptive de-emphasis

is available for Wegener-Panda 1 encoded satellite programs.

5. FM

DECODING

A 2-carrier stereo decoder recovers the left and right signal channels from the demodulated sound carriers. Both the

European and Korean stereo systems are supported.

Automatic FM dematrixing is also supported, which means that the FM sound mode identification (mono, stereo or

dual) switches the FM dematrix directly. No loop via the microcontroller is needed.

2

C-bus or via Easy Standard Programming (ESP). When receiving NICAM

17 02/12/09

TCL M113 Chassis Service Manual

For highly overmodulated signals, a high deviation mode for monaural audio sound single carrier demodulation can

be selected.

NICAM decoding is still possible in high deviation mode.

6. FM

IDENTIFICATION

The identification of the FM sound mode is performed by AM synchronous demodulation of the pilot and

narrow-band detection of the identification frequencies. The result is available via the I2C-bus interface. A selection

can be made via the I2C-bus for B/G, D/K and M standards, and for three different time constants that represent

different trade-offs between speed and reliability of identification. A pilot detector allows the control software to

identify an analog 2-carrier (A2) transmission within approximately 0.1 s.

Automatic FM dematrixing, depending on the identification, is possible.

7. NICAM

DEMODULATION

The NICAM signal is transmitted in a DQPSK code at a bit rate of 728 kbits/s. The NICAM demodulator performs

DQPSK demodulation and passes the resulting bitstream and clock signal to the NICAM decoder and, for evaluation

purposes, to various pins.

A timing loop controls the frequency of the crystal oscillator to lock the sampling instants to the symbol timing of the

NICAM data.

8. NICAM

DECODING

The device performs all decoding functions in accordance with the “EBU NICAM 728 specification”. After locking

to the frame alignment word, the data is descrambled by applying the defined pseudo-random binary sequence. The

device then synchronizes to the periodic frame flag bit C0.

The status of the NICAM decoder can be read out from the NICAM status register by the user. The OSB bit indicates

that the decoder has locked to the NICAM data. The VDSP bit indicates that the decoder has locked to the NICAM

data and that the data is valid sound data. The C4 bit indicates that the sound conveyed by the FM mono channel is

identical to the sound conveyed by the NICAM channel.

The error byte contains the number of sound sample errors (resulting from parity checking) that occurred in the past

128 ms period. The Bit Error Rate (BER) can be calculated using the following equation:

BER = bit errors / total bits≈error byte×1.74×10

-5

9. NICAM

AUTO-MUTE

This function is enabled by setting bit AMUTE to logic 0. Upper and lower error limits may be defined by writing

appropriate values to two registers in the I

2C-bus section. When the number of errors in a 128 ms period exceeds the

upper error limit, the auto-mute function will switch the output sound from NICAM to whatever sound is on the first

sound carrier (FM or AM) or to the analog mono input. When the error count is smaller than the lower error limit, the

NICAM sound is restored.

The auto-mute function can be disabled by setting bit AMUTE to logic 1. In this case clicks become audible when the

error count increases. The user will hear a signal of degrading quality.

If no NICAM sound is received, the outputs are switched from the NICAM channel to the 1st sound carrier.

18 02/12/09

TCL M113 Chassis Service Manual

A decision to enable or disable the auto-mute is taken by the microprocessor based on an interpretation of the

application control bits C1, C2, C3 and C4, and possibly any additional strategy implemented by the user in the

microcontroller software. When the AM sound in NICAM L systems is demodulated in the 1st sound IF and the

audio signal connected to the mono input of the TDA9874A, the controlling microprocessor has to ensure

switching from NICAM reception to mono input, if auto-muting is desired. This can be achieved by setting bit

AMSEL = 1 and bit AMUTE = 0.

10. CRYSTAL OSCILLATOR

The digital controlled crystal oscillator (DCXO) is fully integrated. Only an external 24.576 MHz crystal is required.

11. T

EST PINS

All test pins are active HIGH. In normal operation of the device they can be left open-circuit, as they have internal

pull-down resistors. Test functions are for manufacturing tests only and are not available to customers.

12. P

OWER FAIL DETECTOR

The power fail detector monitors the internal power supply for the digital part of the device. If the supply has

temporarily been lower than the specified lower limit, the power failure register bit PFR in subaddress 0, will be set

to logic 1. Bit CLRPFR, slave register subaddress 1, resets the Power-on reset flip-flop to logic 0. If this is detected,

an initialization of the TDA9874A has to be performed to ensure reliable operation.

13. P

OWER-ON RESET

The reset is active LOW. In order to perform a reset at power-up, a simple RC circuit may be used which consists of

an integrated passive pull-up resistor and an external capacitor connected to ground.

The pull-up resistor has a nominal value of 50 k , which can easily be measured between pins CRESET and

VDDD3. Before the supply voltage has reached a certain minimum level, the state of the circuit is completely

undefined and remains in this undefined state until a reset is applied.

The reset is guaranteed to be active when:

.The power supply is within the specified limits (4.5 to

5.5 V)

.The crystal oscillator (DCXO) is functioning

.The voltage at pin CRESET is

below 0.3VDDD (1.5 V if VDDD= 5.0 V, typically

below 1.8 V).

The required capacitor value depends on the gradient of

the rising power supply voltage. The time constant of the

RC circuit should be clearly larger than the rise time of

the power supply (to make sure that the reset condition is

always satisfied), even when considering tolerance spreading. To avoid problems with a too slow discharging of the

capacitor at

power-down, it may be helpful to add a diode from pin CRESET to VDDD.

It should be noted that the internal ESD protection diode does not help here as it only conducts at higher voltages.

Under difficult power supply conditions (e.g. very slow or non-monotonic ramp-up), it is recommended to drive the

reset line from a microcontroller port or the like.

Description of the DSP

1. LEVEL SCALING

All input channels to the digital crossbar switch are equipped with a level adjustment facility to change the signal

level in a range of ±15 dB. Adjusting the signal level is intended to compensate for the different modulation

parameters of the various TV standards. Under nominal conditions it is recommended to scale all input channels to be

15 dB below full-scale. This will create sufficient headroom to cope with overmodulation and avoids changes of the

volume impression when switching from FM to NICAM or vice versa.

2. NICAM

The NICAM path has a switchable J17 de-emphasis.

3. NICAM

If NICAM is received, the auto-mute is enabled and the signal quality becomes poor. The digital crossbar switches

automatically to FM, channel 1 or the analog mono input, as selected by bit AMSEL. This automatic switching

depends on the NICAM bit error rate. The auto-mute function can be disabled via the I

4. FM (AM)

A high-pass filter suppresses DC offsets from the FM demodulator that may occur due to carrier Frequency offsets,

and supplies the FM monitor function with DC values, e.g. for the purpose of microprocessor controlled carrier

search or fine tuning functions.

An adaptive de-emphasis is available for Wegener-Panda 1 encoded satellite programs.

The de-emphasis stage offers a choice of settings for the supported TV standards.

The 2-channel decoder performs the dematrixing of

and R signals or of channel 1 and channel 2 to L and R signals, as demanded by the different TV standards or user

preferences.

Automatic FM dematrixing is also supported.

Using the high deviation mode, only channel 1 (mono) can be demodulated. The scaling is -6 dB compared to

2-channel decoding.

5. MONITOR

This function provides data words from the FM demodulator outputs and FM and NICAM signals for external use,

such as carrier search or fine tuning. The peak level of these signals can also be observed. Source selection and data

read out are performed via the I

6. DIGITAL CROSSBAR SWITCH

The input channels are derived from the FM and NICAM paths, while the output channels comprise I

audio DACs to the analog crossbar switch. It should be noted that there is no connection from the external analog

audio inputs to the digital crossbar switch.

7. DIGITAL AUDIO OUTPUT

The digital audio output interface comprises an I

equipped with a level adjustment facility that can change the signal level in a ±15 dB range in 1 dB steps. Muting is

possible, too, and outputs can be disabled to improve EMC performance.

2

The I

S-bus output matrix provides the functions for forced mono, stereo, channel swap, channel 1 or channel 2.

Automatic selection for TV applications is possible. In this case the microcontroller program only has to provide a

user controlled sound A or sound B selection.

8. STEREO CHANNEL TO THE ANALOG CROSSBAR PATH

A level adjustment function is provided with control positions of 0 dB, +3 dB, +6 dB and +9 dB in combination with

the audio DACs. The Automatic Volume Level (AVL) function provides a constant output level of -20 dB (full-scale)

for input levels between 0 dB (full-scale) and -26 dB (full-scale).

There are some fixed decay time constants to choose from, i.e. 2, 4 or 8 seconds.

Automatic selection for TV applications is possible. In this case the microcontroller program only has to provide a

user controlled sound A or sound B selection.

9. GENERAL

The level adjustment functions can provide signal gain at multiple locations. Great care has to be taken when using

gain with large input signals, e.g., due to overmodulation, in order not to exceed the maximum possible signal swing,

which would cause severe signal distortion. The nominal signal level of the various signal sources to the digital

crossbar switch should be 15 dB below digital full-scale (-15dB full-scale).

Description of the analog audio section

1. ANALOG CROSSBAR SWITCH AND ANALOG MATRIX

The TDA9874A has one external analog stereo input, one mono input, one 2-channel and one single-channel output

port. Analog source selector switches are employed to provide the desired analog signal routing capability, which is

done by the analog crossbar switch section.

The basic signal routing philosophy of the TDA9874A is that each switch handles two signal channels at the same

time (e.g. left and right, language A and B) directly at the source.

Each source selector switch is followed by an analog matrix to perform further selection tasks, such as putting a

signal from one input channel, say language A, to both output channels or for swapping left and right channels. The

analog matrix provides the functions given in the follow table. Automatic matrixing for TV applications is also

supported.

3. AUDIO DACS

The TDA9874A comprises a 2-channel audio DAC and an additional single-channel audio DAC for

feeding signals from the DSP section to the analog crossbar switch. These DACs have a resolution of

15 bits and employ four-times oversampling and noise shaping.

4. AUDIO OUTPUT BUFFERS

The output buffers provide a gain of 0 dB and offer a

muting possibility. The post filter capacitors of the audio

DACs are connected to the buffer outputs.

5. STANDBY MODE

2. EXTERNAL AND MONO INPUTS

The external and mono inputs accept signal levels of up to 1.4 V

(RMS). By adding external series resistors to provide suitable

attenuation, the external input could be used as a SCART input.

Whenever the external or mono input is selected, the output of the

DAC is muted to improve the crosstalk performance.

Switch diagram for the analog audio section

The standby mode (see Section 7.3.3) disables most functions and reduces power dissipation of the TDA9874A. It

provides no other function.

Internal registers may lose their information in standby mode. Therefore, the device needs to be initialized on returning to normal operation. This can be accomplished in the same way as after a Power-on reset.

TCL M113 Chassis Service Manual PART V. Adjusting Description

1.TMPA8827+M113 software adjustment specification(SAMPLING MODEL:2918AE)

M113 chassis is used as I2C bus control chassis for 25 inch or bigger TV in our company ，use TOSHIBA TMPA8809 TWO IN ONE TV process chip，and software M113 designed by R&D dept. ourselves. First production runing please use flash edition TOSHIBA TMPA8827 to be programmable，then，change to OTP edition TOSHIBA TMPA8827，take care of this point in your production. Secondly， adopting I

2

C bus structure，we can use remote handset to accomplish adjustment, also automatic adjustment instruments can be used in some adjustment items, including pincushion distortion 、H-width、IF VCO can be adjustment by remote handset or automatic adjustment instruments. Of course both the voltage of screen and focus will be adjusted by hands.（remark：if it has NICAM function ，the adjustment way of this module with TDA9874APS can be your reference.）

To solve the problems happened in production process, workers who join to assemble this model should master its specifications. This model TV set have two modes: customer mode，factory mode. The former is setted for customer；the latter is for production in factory and repairing in aftersales. Customer mode can be operated with remote handset or keys in front panel, but factory mode only be operated with remote handset.

The method to enter factory mode is as below: after power on, press“volume▼”on front panel，waiting for the scale to“0”，then press key“DISPLAY” on the remote handset，there will be “D”displayed on the screen shows it enters in factory mode. Now the shortcut keys on the factory adjustment remote handset can be（remark：customer mode remote handset also can be used，it can be used in repairing adjustment，press key“STANDBY” to exit factory mode，but system setting data”6”should be kept the state before storing，do not to change it.）changed factory data and restored in memory.For factory production，you can set “BIT-0” to“1”in menu “OPT”, so everytime you press the remote handset can enter “D-MODE” directlly after open the sets in AC or DC power sets on, also it can be activated by key “D-MODE”on the remote handset，but do not forget to set“BIT-0”to“0”in menu“OPT”and power them on in AC or DC mode one time in the end of production，so the sets will disable factory mode.

The key “I²C”on the remote handset can interrupt the communication CPU with I
