WARNING: Before servicing this chassis, read the “X-RAY RADIATION precaution”, “safety

precaution” and “product safety notice” below.

X-RAY RADIATION PRECAUTION

1. Excessive high voltage can produce potentially hazardous X-RAY 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 22-23kv(14”), 2526kv(20”, 21”) at max beam current. The high voltage must not, under any circumstances, exceed 27.5kv (14", 20”), 29.0kv(21”). Each time a receiver requires servicing, the high

SAFETY PRECAUTION

1. Potentials of high voltage are present when this receiver is operating. Operation of the receiver outside the cabinet or with the back cover removed involves a shock hazard from the receiver.

1) Servicing should not be attempted by anyone who is not thoroughly familiar with the precautions necessary when working on highvoltage equipment.

2) Always discharge the picture tube to avoid the shock hazard before removing the anode cap.

3) Discharge the high potential of the picture tube before handling the tube. The picture tube is highly evacuated and if broken, glass fragments will be violently expelled.

voltage should be checked. It is recommended the reading of the high voltage recorded as a part of the service records. it is important to use an accurate and reliable high voltage meter.

2. The only source of X-RAY Radiation in this TV receiver is the picture tube. For continuous RADIATION protection, the replacement tube must be exactly the same type tube as specified in the parts list.

2. If any Fuse in this TV receiver is blown, replace it with the FUSE specified in the Replacement Parts List.

3. When replacing a high wattage resistor(oxide metal film resistor) in circuit board, keep the resistor 10mm away from circuit board.

4. Keep wires away from high voltage or high temperature components.

5. This receiver must operate under AC260 volts, 50Hz/60Hz. (AC 100~250 volts, 50/60Hz)NEVER connect to DC supply or any other power or frequency.

PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These characteristics are often passed unnoticed by a visual inspection and the X-RAY RADIATION protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this manual and its supplements, electrical components having such features are

identified by designated symbol on the parts list. Before replacing any of these components, read the parts list in this manual carefully. The use of substitute replacement parts which do not have the same safety characteristics as specified in the parts list may created X-RAY Radiation.

(4) Pin Description

No Name Description

1 SOUND IF INPUT The sound equivalent input impedance is 8k5 ohm // 5pF which has to be

taken into account for proper termination of the ceramic filters. The DC impedance is very high. The minimum input signal for catching is l mV rms.

2 EXT AUDIO INPUT An external sound signal (500mVrms) for example from SCART can be

applied to this pin via a coupling capacitor.

The input impedance is 25kohm. 3 VCO REF FILTER The IF VCO tuned circuit is applied to these pin. 4 Its resonance frequency must be two times the IF-frequency and in between a

range of 64-120MHz.

This range is suitable for the IF standards as 33.4, 38.9, 45.75 and 58.75MHz.

The VCO frequency can be adjusted by I2C bus so a fixed coil can be used. 5 PLL LOOP FILTER The PLL loopfilter is a first order filter with R=390 ohm and C = 100nF in

series to ground.

The loopfilter bandwidth is 60kHz and is optimal for both fast catching and

sufficient video suppression for optimal sound performance.

Sound performance can theoretically be improved by adding a small

capacitor (approx.0- 4.7nF) between pin 5 and ground.

This however must be evaluated further because the normal video signal

response should not be effected. 6 IF VIDEO OUTPUT Although the video output impedance is low it is recommended to avoid

high frequency current in the output due to for instance sound trap filters.

This can be achieved by means of an emitter follower at the video output with

a 1 resistor in series with the base. 7 BUS INPUT : SCL Serial clock line 8 BUS INPUT : SDA Serial data line 9 BANDGAP The bandgap circuit provides a very stable and temperature independent

DECOUPLING reference voltage.

This reference voltage (6.7V) ensures optimal performance of the TDA8374

and is used in almost all functional circuit blocks. 10 CHROMA INPUT The supplied C S-VHS input burst amplitude should be nominally 300mVpp

(assumed is a colour bar signal with 75% saturation and with chroma/burst

ratio of 2.2/1 ). The C S-VHS input is internally clamped to 4V via 50 .

The external AC coupling capacitor with 50 forms a high pass filter.

A recommended coupling capacitor is 1 nF; the high pass filter cut off

frequency is then approximately 3KHz. 11 Y/CVBS INPUT The Y S-VHS signal of 1Vpp ( inclusive sync amplitude) is AC coupled to pin11. 12 MAIN The TDA8374 has a main supply pin 12 and a horizontal supply pin 37. Both 37 POSITIVE SUPPLY pins have to be supplied simultaneously.

Notice that the IC has not been designed to use this pin 37 as start pin.

(pin 37 supplies the horizontal oscillator, PHI-1 and PHl-2)

(pin 12 supplies the rest of the circuits in the IC)

The nominal supply voltage is 8V. With min/max values of 7.2-8.8V.

Also in stand-by condition the IC must be supplied with 8V.

No Name Description

A voltage detection circuit is connected to both pins.

- pin12 if V12 <6.8V than a power on reset, POR, is generated. The Hout output is disabled immediate.

- pin37 if V37 <5.8V than the horizontal output is disabled immediate.

13 INT CVBS INPUT It is recommended that the CVBS1 int and CVBS2 ext input amplitudes are 17 EXT CVBS INPUT 1 Vpp (inclusive sync amplitude).

This, because the noise detector switches the 1 loop to slow mode (i.e. auto 1mode when FOA, FOB = 0,0) when noise level exceeds

100mVrms (i.e. at S/N of 20dB). 14 GROUND All internal circuits are connected to this ground pin 14. 15 AUDIO OUTPUT The output signal is volume controlled and is active for both internal and

external audio signals. The nominal gain is +9dB and -71dB, which gives

a total control range of 80dB.

The output signal range therefor is 0.14- 1400mVrms

The bandwidth is >100kHz, the DC level is 3.3V and the output impedance

is 250 . 16 DECOUPLING Voltage variations at pin 16, which can be due to external leakage current or

FILTER TUNING crosstalk from interference sources, should be less than 50mV to ensure that

tuning of filters/delay cells remains correct. 18 BLACK CURRENT For correct operation of the loop CURRENT information is supplied to the

INPUT black current input pin. 19 BLUE OUTPUT The RGB outputs are supplied to the video output stages from pins 21, 20 20 GREEN OUTPUT and 19 respectively. 21 RED OUTPUT For nominal signals (i.e. CVBS/S-VHS, -(R-Y)/- (R-Y), TXT inputs) and for

nominal control settings, then the RGB output Signal amplitudes is typically 2VBLACK_WHITE.

22 V-GUARD INPUT/ Vertical Guard

BEAM CURRENT With this function, the correct working of the vertical deflection can be

LIMITER monitored. If the vertical deflection fails, the RGB outputs are blanked to

prevent damage to the picture tube.

Beam current limitinq

The beam current limiting function is realised by reducing the contrast (and finally the brightness) when the beam current reaches s too high level. The circuit falls apart in two functions:

No Name Description

to the luminance input pin 27. The pin is internally AC coupled to the luminance clamp via a capacitor of 50pF; clamping action occurs during burstkey period.

28 LUMINANCE The luminance output signal is approximately l V black-white with typical

OUTPUT output impedance of 25O ohm. 29 B-Y OUTPUT The maximum output impedance of pins 29 and 30 is 500 when PAL/NTSC 30 R-Y OUTPUT signals are identified. When SECAM is identified by the SECAM add-on and

no PAL/NTSC is already identified by the ASM, then the ASM sets the

-(B-Y)/-(R-Y) output switch open (via DEMSW). This enables the -(B-Y)/-(R-Y) outputs of the TDA8395 to be directly connected

to pins 29 and 3O respectively. 31 B-Y INPUT The -(B-Y),-(R-Y) output signals (supplied from baseband delay line) are AC 32 R-Y INPUT coupled, via a coupling capacitor of 10nF or greater, to the -(B-Y)/-(R-Y) inputs;

both inputs are clamped during burstkey period. 33 SECAM REF The SECAM reference output is directly connected to pin l of the TDA8395 for

OUTPUT SECAM decoding ; it also can be used as a reference for comb filter applications. 34 X-TAL 3.58 To ensure correct operation of both: 35 X-TAL 4.43 - colour processing internal circuits,

- sync calibration internal circuits, it is only allowed to have 3.6MHz Xtals on pin34: both 4.4MHz,3.6MHz Xtals are allowed on pin 35. If pin 35 is not used: then it is left open in application (also XA,XB=O,1 ).

36 LOOP FILTER One of the important aspects of the PLL is the 1oop filter connected to pin 36;

BURST PHASE it influences the dynamic performance of the loop. DETECTOR

38 CVBS OUTPUT The output amplitude is 1Vpp (transfer gain ratio between CVBS1int or

CVBS2ext or CVBS3ext/Ys-vhs and CVBSout is 1). The maximum output impedance is 250 ohm.

39 BLACK PEAK For the correct working of the black stretcher an external time constant should

HOLD CAPACITOR be added at the black peak hold capacitor input.

40 HOR OUTPUT This open collector output is meant to drive the horizontal output stage.

The output is active low, i.e. the line transistor should conduct during the low period of the output.

41 SANDCASTLE Pin 41 is a combined input/output pin.

OUTPUT/ The pin provides a three level sandcastle pulse. FLYBACK INPUT Both burstkey pulse and vertical blanking pulse are always available, the line

blanking pulse is only present when the external flyback pulse is fed to this pin. The line flyback pulse, fed to this pin is used for two functions:

- input signal for the PHI-2 1oop and

- RGB line blanking. (without flyback pulse blanking occurs only during the

burstkey pulse) To ensure correct working of the delay line and SECAM add-on, the output should not be loaded with more than:

- Sandcastle input delay line TDA 4665

- Sandcastle input SECAM add-on TDA 8395

42 PHI-2 FILTER / The loopfilter is a first order filter.

FLASH PROTECT This pin requires a capacitor (C) only.

No Name Description

A flash protection becomes active when this pin is forced >6V. The horizontal drive is switched-off immediately. Once the voltage is <6V the horizontal drive is switched-on again via the slow start procedure.

43 PHI-1 FILTER The loopfilter connected to pin 43 is suitable for various signal conditions as

strong/weak and VCR signal. This is achieved by switching of the loopfilter time constant by changing the PHI-1 output current. Via I2C bus FOA/B, different time constants can be chosen, including an

automatic mode which gives optimal performance under varying conditions. 44 GROUND To this pin are connected the IC-substrate and horizontal output. 45 EAST-WEST DRIVE not used 46 VERT DRIVE + The vertical drive has a current output. The output is balanced which ensures 47 VERT DRIVE - a good common mode behavior with temperature and makes the output signal

less sensitive for disturbances. 48 IF INPUT The PLL frequency range is 32-60MHz with corresponding VCO frequency 49 64-120MHz.

The IF input impedances is 2 in parallel with 3pF and matches the required

load for commonly used SAW filters.

A DC coupling is allowed, so no series capacitors between SAW filter and IF

input are necessary. 50 EHT/OVERVOLTAGE not used

PROTECT INPUT

51 VERT This pin requires a capacitor to ground of l00nF +, - 5%.

SAWTOOTH The optimal sawtooth amplitude is 3.5V and is determined by the external CAPACITOR capacitor and charge current.

The sawtooth bottom-level is 2V. 52 REFERENCE This pin requires a resistor to ground.

CURRENT INPUT The optimal reference current is 100 . which is determined by this resistor.

53 AGC The AGC capacitor value is 2.2 and has been defined for an optimal

DECOUPLING compromise between AGC speed and tilt for all AGC modes CAPACITOR (negative/positive modulation).

54 TUNER AGC This output is used to control (reduce) the tuner gain for strong RF signals.

OUTPUT The tuner AGC is an open collector output which is acting as a variable

current source to ground. 55 AUDIO Only a capacitor has to be connected to this pin that defines the deemphasis

DEEMPHASSIS time constant.

The signal is internally connected through to the Audio switch.

The deemphasis output is fixed, thus not controlled by the volume, and can be

used for SCART. 56 DECOUPLING This pin requires a capacitor of 10 connected to ground.

SOUND The pin acts as a low pass filter needed for the DC feedback loop. DEMODULATOR

Circuit Description

Vision IF amplifier, AFC, video demodulator

The IF signal from the tuner is fed through a SAW filter to the differential IF input (pin 48 and 49). The first IF stage consists of 3 AC-coupled amplifiers with a total gain control range of over 66 dB. The reference carrier for the video demodulator is obtained by a PLL carrier regenerator (eliminating notch filter compromises, as in reference tuned circuits for passive carrier regeneration). Only an oscillator coil is needed( pin 3 and 4) that can be aligned via l2C-bus to the double IF frequency.

The AFC information is derived from the VCO control voltage of the IF-PLL and can be read via I2C-bus. Bit AFB toggles when the picture carrier is exactly at the desired IF frequency (= half the aligned IF-PLL frequency). AFA is active in a window around this point. For fast search-tuning applications this window can be increased by a factor 3 (AFW bit).

Tuner A.G.C.

The automatic gain control (A.G.C.) circuit operates on top sync level at negative modulated signals or on peak white level at positive modulation, selected by MOD bit. The tuner A.G.C. is controlled via pin 54. The tuner A.G.C. take over point (T.O.P.) can be set over a wide range: 0.8 mVrms .. 80 mVrms IF input signal amplitude. The tuner AGC output may have to operate above Vcc of TDA8374. Therefore pin 54 is an open collector output, that can operate from 0.3 up to Vcc+ 1 Volt (at > 2 mA sink current)

PLL sound demodulator

The IF-video output at pin 6 (2Vpp) is fed through a sound bandpass filter and connected to the intercarrier sound IF input pin 1. An alignment free PLL tunes itself to the sound carrier and demodulates it. The non volume-controlled front-end audio signal can be obtained from the deemphasis pin 55 (amplitude 300 mVeff).

Source select switch

TDA8374 input switch can select one of the following sources ;

pin 13 front-end : CVBS l int pin17 : CVBS 2 ext

pin 11.pinlO : Y s-vhs, C s-vhs Selected signal is available at the CVBS output pin 38, in case of Y/C input Y+C are added. It drive teletext and the TDA8395 SECAM add-on. For S-VHS applications, the Y,C input can be selected, independent of the CVBS source switch. TDA8374 Y,C inputs are selected, while the source switch outputs CVBS l int or CVBS 2 ext on CVBS out.

Horizontal synchronization and protection

The synchronization separator adapts its slicing level in the middle between top-sync and black level of the CVBS signal. The separated synchronization pulses are fed to the first phase detector and to the coincidence detector. The -1 loop gain is determined by the components at pin 43 (C+RC). The coincidence detector detects whether the horizontal line oscillator is synchronized to the incoming video. The line oscillator is a VCO-type, running at twice the line frequency. It is calibrated with the X-tal oscillator frequency of the colour decoder and has a maximum deviation of 2% of the nominal frequency, so no alignment is-needed. Calibration is done at start up( the TDA8374 must first know what colour X-tals are connected, bits XA and XB) and after synchronization loss ( -1 coincidence detector “Sync Locked” bit SL).

The second phase detector -2 locks the phase of the horizontal driver pulses at output pin 40 to the horizontal flyback pulse at input pin 41 .

This compensates for the storage time of the horizontal deflection transistor. The - 2 loop filter (C) is externally connected to pin 42. The horizontal phase can be given a static off set via I2C-but (HSH “horizontal shift”) A dynamic correction is possible by current feedback into the - 2 loop filter capacitor.

To protect the horizontal deflection transistor, the ho rizontal drive is switched off immediately when a power failure ( “ Power-On Reset “ bit POR ) is detected. The power failure may have corrupted the contents of the internal data registers, so the TDA8374 should be started up again.

The TDA8374 has a separate supply input (pin 37) that only used as a clean supply voltage for thehorizontal oscillator circuits.

V ertical synchronization

The vertical sawtooth generator drives the vertical output. It uses an external capacitor at pin 51 and a current reference resistor at pin 52. The TDA8374 vertical drive has differential current outputs for DC-coupled vertical output stage, like the TDA8356 . At TDA8356 input pins l and 2 this current is converted into a drive voltage via a resistor.

Geometry processing

With the TDA8374 is possible to implement automatic geometry alignment, because all parameters are adjusted via the I2C bus. The deflection processor of the TDA8374 offers the fo11owing five controls;

- Horizontal shift

- Vertical slope.

- Vertical amplitude

- Vertical S-correction

- vertical shift

Colour decoder

The colour decoder contains an alignment-free X-tal oscillator, a dual killer circuit and colour difference demodulators. Together with the TDA8395 SECAM add-on a multi standard PAL/SECAM/NTSC decoder can be built with automatic recognition. Which standard can be decoded depends on the external Xtals used. Two Xtal pins (34and 36) are present so normally no external switching is required. The I.C. must be told which X-tals are connected (bits XA and XB). This is important, because the X-tal frequency of the colour decoder is also used to calibrate many internal circuit.

The burst phase detector locks the Xtal oscillator with the chroma burst signal. The phase detector operates during the burst key period only, to prevent disturbance of the PLL by the chroma signal. Two gain modes provide:

- Good catching range when the PLL is not Locked.

- Low ripple voltage and good noise immunity once the PLL has locked The killer circuit switches-off the R-Y and B-Y demodulators at very low input signal conditions (chroma burst amplitude). A hysteresis prevents on/off switching at low, noisy signals.

Color standard pin34 pin35 XA XB PAL4.43/SECAM + NTSC-4.43 none 4.43 1 0 PAL4.43/SECAM + NTSC-M 3.58 4.43 1 1

Integrated video filters

The TDA8374 has alignment-free internal luminance delay, chroma bandpass and chroma trap. They are implemented as gyrator circuits tuned by tracking to the frequency of the chroma Xtal oscillator. The chroma trap in the Y signal path is by-passed when Y/C input is selected (S-VHS ). For SECAM an extra luminance delay is build-in, for correct delay of the luminance signal.

RGB output and black current stabilization

The colour difference signals (R-Y, B-Y) are matrixed with the luminance signal (Y) to obtain the RGBout output signals (pins 21,20,29). In the TDA8374 the matrix type automatically adapts to the decoded standard (NTSC,PAL) . Linear amplifiers are used to interface external RGBrn signals (pins 24,25,26) from the SCART connector. These signals overrule the internal RGB signals when the data insertion pin 26 (FBI) is switched to a level between

1.0V and 3.0V.

The contrast and brightness control and the peak white limiter operate on both internal and external RGB signals R,G and B each have their own, independent gain control to compensate for the difference in phosphor efficiencies of the picture tube: so called “white point” adjustment. The nominal amplitude is about 2V black to white, at nominal input signals and control settings.

TDA8374 has a black current stabilization loop, that automatically adjust the black level to the cut-off voltage of the picture tubes three gun cathodes. Since no current is flowing when the voltage the cathode is equal to the cut-off voltage of the tube, the loop stabilizes at a very small gun current. This “black current” of the three guns is measured internally and compared with a reference current, to adjust the black level of RGBout. The black level 1oop is active during 4 lines at the end of the vertical blanking. In the first line the leakage current is measured (max. acceptable 1l00 A). In the next three lines the black levels of the three guns are adjusted. The nominal value of the ‘black current is 10 A. The ratio of the ‘black currents’ for the 3 guns tracks automatically with the white point adjustment, so the back-ground colour is the same as the adjusted white point.

At switch-on of the TV receiver the black current stabilization circuit is not yet active and RGBout are blanked. Before the first measurement pulses appear, O.5 sec delay ensures that the vertical deflection is active, so the pulses will not be visible on the screen. During the measuring lines RGBout will supply 4V pulses to the video output stages. The TDA8374 waits until the black current feedback input (pin 18) exceeds 200 A, which indicates that the picture tube is warm-up. Then the black current stabilization circuit is active. After a waiting time of about 1.0 sec, the blanking of RGBout is released.

Tuning

The AFC information of the TDA8374 is not available as an analogue voltage. Automatic following (=frequency tracking, AFC) can be done via the I2C-bus by software. The TDA8374 AFC window is typically 80 kHz wide. This value is made higher than the 62.5 kHz tuning step, to prevent an automatic following loop from continuously adapting the tuning frequency.. With this AFC window ( 40 kHz) the maximum tuning error is less than 62.5 kHz. For high speed search-tuning-algorithms, the AFC window can be widened to 240 kHz via bit AFW.

TDA8395 SECAM decoder

The TDA8395 is an alignment-free SECAM colour decoder, including a Cloche filter, demodulator and line identification circuit.

The Cloche filter is a gyrator-capacitor type. Its frequency is calibrated in the vertical retrace period. The calibration reference( pin 1 ) is obtained from the TDA8374 color X-tal oscillator (pin 33). Pin 7 is a decoupling for the Cloche reference. The voltage change at this pin due to leakage currents should be lower than 10 mV, during field scan, resulting in a capacitor of minimal 100 nF. Pin 8 is the reference capacitor for the PLL. The voltage variation during field scan at this pin should be lower than 2 mV , resulting in a capacitor of 220 nF.

The sandcastle input (pin 15) is connected to TDA8374 pin 41 and is used for generation of the blanking periods and provides clock information for the identification circuit. The CVBS source select output (TDA8374 pin 38) supplies SECAM chroma to pin 16 of the TDA8395. This is demodulated by a PLL demodulator, that uses the reference frequency at pin l and a bandgap reference to obtain the desired demodulation characteristic.

If the digital line identification in theTDA8395 detects SECAM, pin 1 will sink a current of 150 (A out of TDA8374 SECAMref pin 33. When the TDA8374 has not detected PAL or NTSC, it will respond by increasing the voltage at pin 33 from 1.5V to 5V. Now the TDA8374 color difference outputs pin 30 and 29 are made high-ohmic and the TDA8395 output pin 9 and 10 are switched on. These outputs will be disconnected and high-ohmic when no SECAM is detected for two frame periods, the decoder will be initialized before trying again.

Base band delay line TDA4665

TDA4665 is an integrated double baseband delay line of 64 S. It couples to the TDA8374 and TDA8395 without any switches or alignments. The TDA4665 consist of two main blocks:

- Two delay lines of 64 sec in switched capacitor technique

- Internal clock generation of 3 MHz, line locked to the sandcastle pulse The TDA4665 operates according to the mode demanded by the colour transmission standard:

- For PAL it operates as geometric adder to satisfy the PAL demodulation requirements

- In NTSC mode it reduces cross-colour interference (comb-filtering)

- For SECAM it repeats the colour difference signal on consecutive horizontal scan lines.

A sandcastle pulse is connected to pin 5. The top pulse voltage (should not exceed 5 V) can be directly coupled to the 5 V sandcastle output of the TDA8374. The R-Y and B-Y colour difference signals (from TDA8374 pins 30 and 29) are AC-coupled and clamped by the input stages at pins 16 and 14. An internal 6 MHz Current controlled oscillator is line locked via a PLL to the sandcastle pulse at pin 5. This clock drives the delay lines to obtain the required 64 sec. Sample and hold low pass filters supress the clock signal. The original and the delayed signals are added, buffered and fed to the output pins 11 and 12. These are AC-coupled to the R-Y and B-Y colour difference input pin 32 and 31 of TDA8374.

The TDA4665 needs a 5 V supply voltage on pin l for the digital part and on pin 9 for the analog part.

TDA8356 vertical deflection.

The TDA8356 is a vertical deflection circuit. It can be used in 90 deflection systems with frame frequencies from 50 up to 120 Hz With its bridge configuration the deflection output can be DC coupled with few external components. Only a supply voltage for the scan and a second supply for the flyback are needed. The TDA8356 can drive max.2A.

The vertical drive currents of TDA8374 pins 47 and 46 are connected to input pins l and 2 of the TDA8356. The currents are converted into a voltage by a resistor between pins 1 and 2. Pin2 is on a fixed DC level (internal bias voltage) and on pin l the drive voltage can be measured (typical 1.8 Vpp).

The drive voltage is amplified by ‘A’ and fed to two amplifiers ‘B’ and ‘C’, one is inverting and the other is a non inverting amplifier. The outputs (pins 4 and 7) are connected to the series connection of the vertical deflection coil and feedback resistor . The voltage across feed back resistor is fed via pin 9 to correction amplifier ‘D’, to obtain a deflection current which is proportional to the drive voltage.

The supply voltage for the TDA8356 is 16V at pin 3. The flyback generator has a separate supply voltage of 45V on pin 6.

The guard pulse is useful to synchronize OSD.

Horizontal deflection

The circuit contains horizontal drive, line output transformer. The horizontal driver pulses from the TDA8374 are amplified in the horizontal drive circuit, to get sufficient base-drive current for the high voltage switching transistor Q401. During the horizontal scan period( =52 s) Q401 will conduct, and a sawtooth current flows from +110/123V through the primary winding of the FBT to ground. After this time Q401 is switched off and the energy stored in the FBT during the scan period will be transformed to the flyback capacitor C410. This energy transfer will take place in a cosine shape because the primary of the FBT and C410 from a resonant circuit. The time the energy is transferred from FBT to C410 and back to the FBT, is called the flyback time and will take place in about 12 s. The flyback peak voltage is about 8 times the scan voltage.

In series with the horizontal deflection coil there is a (damped) linearity corrector coi1. During the scan there is some loss in the resistance of the deflection coi1. In the first part of a line the linearity corrector stores some energy in a permanent magnet until it is saturated. This improves the linearity of the horizontal scan speed. The required S correction for the picture tube can be adjusted with the value of C411.

The beam current limiting information (BeamCurr) is derived from the foot of the H.V winding of the FBT. This is connected via resistor to +8V. As the beam current increase, the voltage on line BeamCurr decreases. BeamCurr is damped by a integration filter before it is fed back to TDA8374 pin 22. The TDA8374 will decrease the contrast (and eventually the brightness) to limit the average beam current.

Video amplifiers

Three TDA6106Q integrated video amplifiers drive cathode of the picture tube directly. They are protected against CRT flashover discharges and ESD (electro static discharge).

The three video amplifiers, have a beam current output I black, used by the TDA8374 black current loop to control the black level on the cathodes. The outputs can be connected together because the black current 1oop sequentially controls the black level for each cathode.

The amplification of the TDA6106Q is set by the resistors between pin 3 and 9 and between pin 3 (negative-input) and the TDA8374 output. There are no alignment any more on the CPT panel, because of the automatic black current stabilization and because the white point adjustment can be done in the TDA8374 via I2C bus.

Power Supply STR-S5707

(1) VIN terminal, start-up circuit

A start-up circuit is to start and stop a operation of a control IC by detecting a voltage appearing at a VIN terminal (pin-9). At start up of a power supply, when a voltage at the VIN terminal reaches to 8V (typical) by charging up C807 by the function of a start-up resistor, R803, a control circuit starts operating by the function of the start-up circuit. After the control circuit starts its operation, power source is obtained by smoothing voltage appearing at winding of pin6-7 of T801.

(2) Oscillator, F/B terminal voltage (Pin 7)

A oscillator generates pulse signals which turns a power transistor on and off by making use of charge and discharge of C1 and C2 incorporated in the Hybrid IC. Constant voltage control of a switch-mode power supply is performed by changing both ON-time and OFF-time except when the load is light (ex. remote control stand-by mode of TVs). The ON-time is controlled by changing a current charged by C1, which is as the result of that the detection winding of pin5-7 of T801, which detects a change of voltage in a secondary side, connected to the sensing terminal (Pin 7) has the current in accordance with an output signal from an output voltage detection circuit (an error amplifier) built in. As an AC input voltage to the power supply gets the higher and a load current the smaller, the current flowing to the SENS terminal gets the larger, and the ON-time gets the shorter.

(3) Function of INH terminal (Pin 6), control of OFF-time

Signal to the INH terminal is used as inputs to COMP.1 and COMP.2 inside of the control IC. A threshold voltage of COMP.1, VTH1 is set at 0.75V (Ta=25°) and an input signal to a drive circuit becomes almost 0V (the power transistor is in OFF mode) when a voltage at the INH terminal reaches the VTH1. A threshold voltage of COMP.2, VTH2, is set at 1.5V (Ta=25°). When the INH terminal voltage reaches VTH2, an output from COMP.2 reverses (the power transistor is in on mode).

Quasi-resonant operation

By inputting the voltage of winding of pin6-7 of T801 which is synchronized with the energy discharge time of a secondary winding, pin14(or 15)-16 of T801, to the INH terminal through D805 and R809, quasi-resonant operation can be achieved.

When the power transistor turns off and a voltage higher than VTH2 is applied to the INH terminal, C3 immediately discharges and then starts charging again. Even after the discharge of energy of a secondary winding is completed, VINH does not immediately increases. When it gets lower than VTH1, the transistor turns on.

Stand-By Mode

While being in remote control stand-by mode, the output voltage is kept on providing to the secondary side and the power transistor operates at A class mode.

By connecting INH terminal (Pin 6) to the GND, the OFF-time of the power transistor is fixed at set time ( T OFF = 50usec at Ta = 25 ) of the built-in oscillator, and only ON-time changes depending on input and output conditions of the power supply. Therefore, it enables to hold an oscillation frequency in light mode below 20KHz (typical).

(4) Drive circuit

The STR-S5707 applies the proportional drive system in order to minimize turn-on and saturation loss, and storage time.

(5) OCP (over-current protection) function

Over-current protection is performed pulse by pulse by directly detecting collector current of the power transistor. Detecting voltage is set to -1V below a reference point of GND (ground).

(6) Latch circuit

It is a circuit which sustains an output from the oscillator low and stops operation of the power supply when over-voltage protection (OVP) circuit and thermal shutdown (TSD) circuit are in operation. As the sustaining current of the latch circuit is 500 A maximum when VIN terminal voltage is 4V, the power supply circuit sustains the off state as long as current of 500 A minimum flows to VIN terminal from a start-up resistor. In order to prevent a malfunction to be caused by a noise and so on, delay time is provided by C1 incorporated in the IC and, therefore, the latch circuit operates when the OVP or TSD circuit is in operation, or an external signal input is provided for about 10 sec or longer. In addition, even after the latch circuit start operating, the constant voltage regulator (Reg) circuit is in operation and the circuit current is at high level. As a result, VIN terminal voltage rapidly decreases. When VIN terminal voltage becomes lower than the shutdown voltage, VIN(OFF) (4.9V typical), it starts increasing as the circuit current is below 500 A. When it reaches the ON-state voltage, VIN (ON) (8V typical), VIN terminal voltage starts decreasing because the circuit current increases again. When the latch circuit is on, VIN terminal voltage increases and decreases within the range from 4.9V typical to 8V typical and is prevented from abnormally rising. Cancellation of the latch is done by decreasing VIN terminal voltage below 3.3V. The power supply can be restarted after disconnecting an AC input to the power supply once.

(7) Thermal shutdown circuit

It is a circuit to trigger the latch circuit when the frame temperature of the IC exceeds 150 (typical). Although the temperature is actually sensed at the control chip, it works against overheating of the power transistor as the power transistor and the control IC are mounted on the same lead frame.

(8) Over-voltage protection circuit

It is a circuit to trigger the latch circuit when VIN terminal voltage exceeds 11V (typical). Although it basically functions as protection of VIN terminal against over-voltage, since VIN terminal is usually supplied from the drive winding of the transformer and the voltage is proportional to the output voltage, it also functions against the over-voltage of secondary output which causes when the control circuit opens or in some other events.
