X-RADIATION PRECAUTION

1 The excessive high voltage can produce potentially hazardous X-RADIATION. To avoid such hazards the high voltage must not exceed the specified limit. The nominal value of the high voltage of this receiver is 24 0KV at zero beam current (minimum brightness). The high voltage must not, under any circumstances, exceed 30KV. Each time a receiver requires servicing and the high voltage should be checked following the HIGH VOLTAGE CHECK procedure in this manual. It is recommended that the reading of the high voltage should be recorded as a part of the service record

It is important to use an accurate and reliable high voltage motor

2 The only source of X-RADIATION is thos TV receiver it is the nicture tube For continued X-RADIATION protection the replacement tube must be exactly the same type as specified in the parts list
3 some parts in this receiver have special safety related characteristics for X-RADIATION protection. For continued safety, the parts replacement should be undertaken only after referring to the PRODUCT SAFETY NOTICE.

SAFETY PRECAUTION

Warning : The serivce should not be attempted by anyone unfamilliar with the necessary precautions in this receiver. The followings are the necessary precautions to be observed before servicing

Since the chassis of this receiver is directly connected to the AC power line-(Hot chassis), an isolation transformer should be used during any dynamic service to avoid possible shock hazards.

1. Always discharge the picture tube anode to the CRT conductive coating before handling the picture tube. The picture tube is highly evacuated and if broken, the glass fragments will be violently expelled. Use shatterproof goggles and keep the picture tube away from the bare body during a handling
2. When replacing a chassis in the cabinet, it is always certain that all the protective devices are put back in place, such as non - metallic control knobs, insulating covers, shields, isolation resistor-capacitor network, etc.
3 Before returning the set to the customer, always perform an AC leakage current check on the exposed metallic parts of the cabinet, such as antennas, terminal, screwheads, metal overays, control shafts, etc. To be sure the set is safe to operate without danger of electrical shock. Plug the AC line cord directly to the AC outlet (do not use a line isolation transfomer during this check). Use an AC voltmeter having 5000 ohm per volt or more sensitivity in the following manner. Connect a 1500 ohm 10 watt resistor, paralleled by a 0.15 µ F,AC type capacitor, between a good earth ground(water pipe.conduit etc.)and the exposed metallic parts, one at a time. Measure the AC voltage across the combination of 1500 ohmresistor and 0.15µ F capacitor. Reverse the AC plug at the AC outlet and repeat the AC voltage measurements for each exposed metallic part. The measured voltage must not exceed 0.3volts RMS. This corresponds to 0.2 milliamp AC. Any value exceeding this limit constitutes a potential shock hazard and must be corrected immediately.

2.INTRODUCTION

The IC SDH209 controls the bipolar switching transistors and performs all necessary regulation and function in free running flyback converters.

The flyback converter is the most cost saving SMPS for CTV and VCR. But as the frequency goes up according to the increase of the input AC voltage and the reduction of power consumption an abnormal oscillation like intermittent oscillation or over voltage can happen easy unless the frequency rise is restrained.

SDH209 having a built-in mono-multi vibrator which is triggered at transistor switched off and generates a pulse of constant width to keep the transistor off for the pulse period, will keep switching frequency less than 120KHz.

SDH209 having a built-in constant DC current source will achieve the small drive power consumption at higher AC input and achieve the sufficient drive current at lower AC input.

Owing to the above two built-in circuits, SDH209 can get good regulation and high efficiency over a wide AC input range and keep stable oscillation at very small load.

In the standard connections, the constant voltage charged up at the capacitor is used and also used to sense voltage. So, the transformer and circuit are both simple.

Free running frequency of flyback converter is expressed by the following formula.

$f = \frac{1}{2 \cdot LP \cdot PIN} \cdot \frac{V^{3}IN}{\left(1 + \frac{ns}{np} \cdot \frac{VIN}{Vo}\right)^{2}}$

where, LP Primary inductance

Pin : Input power
ns : Secondary winding turns
np : Primary winding turns
Vin : Input DC voltage

Vo : Output DC voltage

As the above formula, the frequency f goes up according to the increase of Vin and the decrease of Pin.

Mono-multi vibrator built-in SDH209 restrains the rise of switching frequency.

This mono-multi vibrator generates 4µsec pulse every end of Ton period.

That is, this mono-multi vibrator is triggered by signal which is produced when the transistor is switched off. The transistor is unable to be switched on again while the mono-multi vibrator's output is high.

While the transistor is off, the primary inductance of transformer and the floating capacitance or capacitor installed across the snubber diode compose a resonant loop and oscillate. This resonant frequency depends on the primary industance and capacitance.

When 4µsec over, the transistor is released to be switched on again. The time of switch on is approximately 4µsec plus half cycle of resonant frequency from the time of switch off.

Capacitors installed across the snubber diode, across the secondary diodes and across C-E of the transistor affect to the resonant frequency. In order to obtain the stable stand-by oscillation, a total equivalent capacitance is recommended to be less than 330pF. Total equivalent capacitance Ceq is calculated.

Ceq = Csn + Sce + $\left(\frac{ns_1}{nn}\right)^2 \cdot Cs_1 + \left(\frac{ns_2}{nn}\right)^2 \cdot Cs_2$

Page 10

where, Csn : Across the snubber diode

Cce : Across C-E of the transistor
np : Primary winding turns
ns1 : Secondary winding S1 turns
ns2 : Secondary winding S2 turns
Cs1 : Across the diode of S1
Cs2 : Across the diode of S2

Remarks : Capacitance includes a diode junction capacitance and a floating capacitance. Oscillation at no load is stable and its power loss is small because of the above mechanism.

Operation of Over Load

The formula of frequency f shows that f goes down when Vo is smaller than the rated value. When the switch is turned on, Vo starts from zero.

Therefore, the ordinary SMPS makes the whistle sound when starting up.

But, Ton limiter built-in SDH209B limits Ton duration regardless of Vo value.

So, no whistle is made at starting up.

This Ton limiter also works as a protector when the transistor is switching at the over load. Particularly when the input AC voltage is lower than the rated value, Ton becomes longer and the saturation loss increases. But Ton limiter stops becoming longer and protect the transistor from thermal run away.

Operation at Output Short

When the input AC voltage is higher than 220V. Ton limiter is not enough to protect the transistor from the over current. So, the current limiter is provided.

The instantaneous locus at the output short has not been taken clear in the picture. But the locus is expanded to 680V and 3.8A. Therefore, transistor's SOA is required bigger than this point. When the output short is further continued, the locus becomes shrinked and even a dead short will not destroy the transistor.

Because the constant DC current source for base drive is empty due to the dead short and then the transistor does not switch at a large current.

Transformer

1)Primary and Secondary Turn Ratio The value of (Np/Ns) - Vo is factor to determine switching duty, Ic peak, Vce peak and frequency. The recommended value is like the below

2)Leakage Inductance

The recommended value is 1% of the primary industance.

3)Magnetic Saturation Current

2)Actuating Description

- Colour Decoder

The colour decoder contains an alignment-free X-tal oscillator, a dual killer circuit and the colour difference signals demodulators. The decoder adapts automatically for PAL and NTSC signals. Two X-tal pins are present so no external switching is required. With the SECAM add-on decoder TDA8395 an alignment free multi-standard

decoder can be built with an automatic selection. This makes the application of the TDA8362 very flexible. The following applications are possible:

- PAL/SECAM:

In this application pin 27 is not used for Hue-control but for the chroma signal for the SECAM add-on circuit. Pin 27 has to be connected to the supply line 8V via a series resistor of 10k a . Together with the alignment-free SECAM add-on circuit TDA8395 a PAL/SECAM decoder is realized.

The burst phase detector locks the X-tal oscillator with the burst signal. Two gain modes provide an increased catching range when the PLL is unlocked and a low ripple voltage and a good noise immunity when the PLL is locked.

The burst phase detector operates during the burst key period only, to prevent the PLL from being disturbed by the chroma signal.

The killer circuit switches off the R-Y and B-Y demodulators at too low input signal condition (burst amplitude). Proper hysteresis prevent the constant on/off switching at a certain input level.

Page 13

4)IC Specification (TDA8395)

a)Introduction

The TDA8395 is an alignment-free SECAM colour decoder and can be used in conjunction with the TDA8362. It includes the Cloche filter, demodulator and identification circuit. The TDA8395 application needs very few external components, the deemphasis is internally calibrated.

The cloche filter is a gyrator-capacitor type filter. Its resonance frequency is controlled during the calibration period and offset during scan for the right resonance frequency. The required reference frequency for calibration must be connected at pin 1 and is obtained from the TDA8362 (pin 32).

The two(or three)-level sandcastle pulse has to be connected at pin 15 (TDA8362 pin38) and is used for

blanking periods and provides the clock information for the identification circuit.

The chroma signal at pin 16 connected to pin 27 of TDA8362, is demoduleted by a PLL demodulator, which uses the reference frequency and a bandgap reference to force the PLL to the desired demodulation characteristic.

Digital line identification is implemented to check the incoming signal for SECAM. If SECAM is detected, pin 1 will sink a current of 150µA. Together with the TDA8362 the voltage at this pin will become high (5.5V). In this case the colour difference signal outputs will be switched on. These outputs will be disconnected and the high-ohmic when no SECAM is detected for two frame periods, the demodulator will be initialized before trying again.

5)IC specification (TDA4661)

a)Introduction

The TDA4661 are integrated the baseband delay lines of 64µS for colour television receivers. It can be connected to the

b)Block-Diagram

TDA8362 and TDA8395 without the need of switches and alignments. The TDA4661 consists of two main blocks:

-Two comb filters with a delay time of 64µ sec in switched capacitor technique.

-Internal clock generation of Змнz, line locked via the sandcastle pulse.

The TDA4661 operates according to the mode demanded by the colour transmission standard. In the PAL mode it operates as a geomentric adder to satisfy the requirements of PAL demodulation, in the NTSC mode it reduces the cross-colour interference (comb-filtering) and in the SECAM mode the delay line repeats the colour difference signal on consecutive horizontal scan lines

The colour difference signals are AC-coupled to pin 14 and 16 and clamped by the input stages. The internal clock drives the delay lines to obtain the required 64 µ sec. The clock pulses are derived from a 6MHz Current Controlled Oscillator which is the line locked via a PLL with the sandcastle pulse, connected at pin 5. Sample and hold low pass filters suppress the clock signal. The delayed and the un-delayed signals are added, buffered and fed to the output pins 11 and 12.

2)Actuating Description

a)IF amplifier

The IF-amplifier contains 3 AC-coupled control stages with a total gain control range which is in excess of 60 dB. The sensitivity of the circuit is comparable with that of modern IF-IC's. The reference carrier for the video demodulator is obtained by means of the passive regeneration of the picture carrier. The external reference tuned circuit is the only remaining adjustment of the IC. The polarity of the demodulator can be switched so that the circuit is suitable for both positive and negative modulated signals.

The AFC-circuit is driven with the same reference signal as the video demodulator. To avoid that the video content

disturbes the AFC operation a sample-and-hold circuit is applied. The capacitor for this functions is internal. The AFC output voltage range is 6 Volts.

The AGC-detector operates on top-sync or top white-level depending on the position of the demodulator. The AGC detector time-constant capacitor is connected externally. This is mainly because of the flexibility of the application. The time-constant of the AGC system during positive modulation is rather longer to avoid visible variations of the signal amplitude. To obtain an acceptable speed of the AGC system a circuit has been included which detects whether the AGC detector is activated every frame period. When 3 frame periods no action is detected, the speed of the system is increased.

The circuit contains a video identification circuit which is independent of the synchronization circuit. Therefore the search tuning is possible when the display section of the receiver is used as a monitor. The ident output voltage is low when no transmitter is identified. In that condition the sound demodulator is switched off (mute function). When a transmitter is identified the voltage is high. The voltage level is dependent on the frequency of the incoming chroma signal.

b)AGC Tuner AGC and AFC

The A.G.C. detector operates at top-sync level for signals with negative modulation and at peak-white level for positive modulated signals. This A.G.C. detector is gated for negative modulated signals to reduce the sensitivity of impulsive noise.

The time constant capacitor (C117) is connected externally at pin 48. For positive modulated signals the A.G.C. time constant is long to avoid visible variations of the video output signal. To obtain an acceptable A.G.C. speed with positive modulation an extra circuit checks whether the A. G.C. detector is activated every frame period. The speed will be increased if this circuit detects that the video output signal has not reached 80% of peak white level for approximately 100mS.

The tuner AGC take-over point can be set by adjusting the DC-voltage at pin 49, with a potentiometer of 10 kg (VR101).

Page 16

The tuner A.G.C. (pin 47) is an open collector output stage with an output swing of 2mA min. The voltage swing,required by the tuner, can be obtained with an external resistor network, connected at pin 47. Pin 47 may rise 2V above the actual supply voltage, without damaging the IC.

This feature simplifies the application, because most

tuners require a 9V A.G.C. voltage level for min. gain. The A.F.C. circuit is driven by the same reference signal as the video demodulator.A sample and hold circuit avoids video break-through from the video demodulator to the A.F.C. voltage. The A.F.C. output voltage range is from 0 to Vcc, the stepness of the A.F.C. slope can be influenced by resistors R114 and R115.

3)IC Block-Diagram (TDA8362)

4.SOUND SECTION

1)Block-Diagram

2)Actuating Description

The sound bandpass and trap filters have to connected externally. The filtered intercarrier signal is fed to a limiter circuit and is demodulated by means of a PLL demodulator. This PLL circuit itself tunes automatically to the incoming signal so that no adjustment is required.

The volume is the DC-controlled. The composite audio output signal has the amplitude of 700mV RMS at maximum volume control setting. The deemphasis capacitor has to be connected externally. The noncontrolled audio signal can be obtained from this pin (via a buffer stage). The amplitude of this signal is 350mV RMS. The external audio input signal must have an amplitude of 350MV RMS. The audio/video switch is contolled via the chroma input pin.

Audio input signal from an external source (SCART) with an amplitude up to 350mVrms (+/- 6 dB) can be fed to pin 6. The audio switch is controlled via the chroma input pin 16, as described in Chapter 2.1.8. The volume control operates upon the external audio input signal, when the

TDA8362 is switched to the external mode

When the TDA8362 is switched for video signals with the positive modulation, the demodulated AM-sound signal can be connected to the external audio input at pin 6 under the operation of the volume control.

4) IC Specification (TDA1013A)

a)Introduction

The TDA1013A is a monolithic integrated audio amplifier cicuit with D.C. volume control in a 9-lead single in-line (SIL) plastic package. The wide supply voltage range makes this circuit very suitable for applications in mains fed apparatus such as television receivers and record players.

The D.C. volume control stage has a logarithmic control characteristic with a range of more than 80 dB; control can be obtained by means of a variable D.C. voltage between 3.5 and 8 V.

The audio amplifier has a well defined open loop gain and a fixed integrated closed loop gain. This offers an optimum in number of external components, performance and stability.

The SIL package (SOT-110B) offers a simple and lowcost heatsink connection.

b)Block-Diagram

Page 18

2)Actuating Description

The incoming video signals, pin 13 for the internal signal and pin 15 for an external CVBS signal, are fed to the synchronization separator circuit. Internally the black level and the top sync. level are detected, next the synchronization pulses are amplified to a fixed level and sliced at 50% of that level. In this way a very good synchronization performance is obtained. The separated synchronization pulses are fed to the first phase detector circuit and to the coincidence detector. The components which determine the loop gain of the first phase detector are connected at pin 40 (C401, C402 and R402). The coincidence detector is only used to detect whether the line oscillator is synchronised, not for transmitter identification.

The line oscillator is running at twice the line frequency and is derived from the X-tal oscillator frequency of the colour decoder, consequently no adjustment is required. The free-running frequency has a maximum deviation of 2% compared to the nominal frequency.

The second phase detector generates the pulses for the horizontal driver stage (pin 37).

The loop filter capacitor (C404) is connected at pin 39. Horizontal shift can be obtained by a potentiometer and series resistor (R401 and R402) connected at pin 39

The TDA8362 has a separate start-up circuit for the horizontal oscillator (pin 36). In case this feature is used for starting the horizontal deflection the resistor connected at the base of the horizontal driver

transistor (Q401) must be connected to the start supply as well (pin 37 is an open collector). For applications which do not require a start-up function pin 36 must be connected to the main supply voltage (8V).

The vertical drive pulses (pin 43) are generated by a divider circuit. The vertical ramp generator components are connected at pin 42. Capacitor C311 is charged via two resistors, one resistor connected to a stabilized supply voltage (R313). In this way the vertical amplitude will be kept constant with different picture contents.

AC and DC feedback voltage from the vertical deflection stage must be connected at pin 41

1.INTRODUCTION

CTV340S(SPM 109B) is a low cost television receiver control system bases on the PCA84C641 microcontroller. It is a voltage synthesis tuning (VST) system which can be used all over the world. All relevant control functions of the system are displayed via the on-screen display circuitry of the microcontroller. Herewith two independent lines of 16 characters with 4 different sizes and in 7 different colours can be displayed. All analogue picture settings are controlled with 4 on-chip digital to analogue convertors. The fifth digital to analogue converter can be used for volume in a mono-only option, or full sound (Voume, Bass, Treble, Balance) can be controlled in a German Stereo and/or Nicam sound configuration. This system is colour standard independent.

A four page teletxt system, based on the VIP2(SAA5231), ECCT(SAA5243) and display memory, can be controlled indirectly via a second microcontroller. This offers the possibility of a sophisticated teletext system with special features like FASTEXT, TOP, LIST, packet X/26 decoding (for Spain and Eastern Europe).A minimum amount of

software is spent to transfer the teletxt commands from the remote control to this special teletext controller. A second option is a system with no teletext at all.

The CTV340S(SPM109B) system fulfils a numerous and varied requirements and has options to make it applicable to all markets.

6.ALIGNMENT and ADJUSTMENT

- This Models has only one adjustment -

1.GENERAL INFORMATIONS

All the adjustments are thoroughly checked and corrected when the receiver leaves the factory. Therefore the receiver should operate normally and produce proper colour and B/W picture upon installation. However the minor service adjustments may be required depending on the particular location in which the receiver is operated. This receiver is shipped completely in carboard carton. Carefully draw out the carton and remove all the packing materials. Pulg the power cord into a convenient two pin power outlet. Turn the receiver ON and adjust the fine tuning for the best picture detail. Check and adjust all the customer controls such as BRIGHTNESS, CONTRAST and COLOUR Controls to obtain natural colour or B/W picture.

2.AUTOMATIC DEGAUSSING

A degaussing coil is mounted around the picture tube so that the external degaussing after moving the receiver is nomally unnecessary, providing the receiver is properly degaussed upon installation. The degaussing coil operates for about 1 second after the power to the receiver is switched ON. If the set is moved or faced in a different direction, the power switch must switch off at least 10 minutes in order that the automatic degaussing circuit is operated property.

If the chassis or parts of the cabinet becomes magnetized and cause poor colour purity, use an external degaussing coil.

Slowly move the degaussing coil around the face-plate of the picture tube, the sides and the rear of the receiver and slowly withdraw the coil to the distance of about 2m before disconnecting it from the AC source. If the colour shading still persists, perform the COLOUR PURITY ADJUSTMENT and CONVERGENCE ADJUSTMENTS procedures, as mentioned later.

3.HIGH VOLTAGE CHECK

CAUTION : There is no HIGH VOLTAGE ADJUSTMENT on this chassis. But B+ power must be adjusted in +125V under the full colour bar pattern and nomal picture control level.

1)Connect an accurate high voltage meter to the second, anode of the picture tube.
2)Turn on the receiver. Set the BRIGHTNESS and CONTRAST control to minimun(Zero beam).
3)The high voltage should be measured less.
4)Rotate the BRIGHNESS and CONTRAST control to the both extremes to be sure. The high voltage does not exceed the limit under any conditions.

4.HORIZONTAL PHASE ADJUSTMENT

If you want to move the center of picture, adjust HORIZONTAL phase control(VR401)

Page 23

5.VERTICAL HEIGHT ADJUSTMENT

The SIZE control(VR301) on the main board changes the size of the picture, having an equal effect on the top and the bottom.

6.SCREEN ADJUSTMENT

1)Tune in an active channel.

2)Make the picture normal condition (no blooming or noflyback line) with the VR screen.

7.FOCUS ADJUSTMENT

Adjust the FOCUS control on FBT for well defined scanning lines in the center area of the screen.

8.R-F AGC ADJUSTMENT

Tune the set in the strongest station in your area. Turn the AGC control(VR101) on the IF board to fully clockwise position

3)Adjust the AGC control until noises (snow) dissappear from the screen.

9.COLOUR PURITY ADJUSTMENT

NOTE : Before attempting any purity adjustments, the receiver should be operated for at least fifteen minutes. Purity adjustment requires Rubber Wedge kit.
1)Demagnetize the picture tube and cabinet using a degaussing coil.
2)Turn the CONTRAST and BRIGHTNESS controls to the maximum.
3)Receiver the green colour pattern.
4)Loosen the clamp screw holding the yoke, and slide the yoke backward or forward to provide the vertical green belt (zone) in the picture screen.
5)Remove the Rubber Wedges.
6)Rotate and spread the tabs of the purity magnet(See Fig.3) around the neck of the picture tube until a green belt is obtained in the center of the screen. And at the same time, center the raster vertically by adjusting the magnet.
7)Move the yoke slowly forward or backward until a uniform red screen is obtained. Tighten the clamp screw.

8)Check the purity of the red and blue raster.

9)Tighten the clamp screw of the yoke temporarily.

10)Obtain a white raster ; referring to the "CRT WHITE BALANCE ADJUSTMENT ".

11)Proceed with convergence adjustment.

f)Set the blue and red drive controls to the mechanical center position.
g)Set the screen VR control on FBT to the minimum position (fully counter clockwise).
h)Connect 1 to 2 and 3 to 4 in CN202.

2)STEPS

a)Rotate the SCREEN control on FBT (T444) gradually clockwise until the first horizontal line appears slightly on the screen.

b)Adjust the two CUT - OFF controls to obtain the sli-

ghtly lighted horizontal line in the same levels of three colours(red, green,blue).

The line look like white if the CUT - OFF controls are adjusted property.

c)Reset the CN202 on the MAIN board to obtain a raster ("NORMAL" Position).
d)Adjust the blue and red drive controls to obtain proper white - balanced picture in high light areas.

e)Set the contrast control to the minimum position and turn the brightness control slightly counterclockwise to obtain a dark gray raster.

Then check the white balance in low brightness.
If the white balance is not enough, repeat steps 1) -4) for the correct white balance.
11.CONVERGENCE ADJUSTMENTS
- NOTE : Before attempting any convergence adjustment, the receiver should be operated for the least fifteen minutes.
- 1)Center Convergence Adjustment

a)Receive the crosshatch pattern with a colour bar signal generator.

b)Adjust the BRIGHTNESS and CONTRAST Controls for a well defined pattern.
c)Adjust the two tabs of the 4-pole Magnets to change the angle among them (See Fig.2) and superimpose the red and the blue vertical lines in the center area of the picture screen. (See Fig.2).
