INTRODUCTION

This is a 110 chassis capable of driving 28-29,32,33 tubes at appropriate currents. The chassis have, Frequency Controlled Tuning (PLL), and control system for multi-standard (Pal,Secam,BG,DK,L/L ,NTSC,M,N ) TV receivers with on-screen-display (OSD) for all relevant ,I/I control functions. The system is based on the one-chip I2C bus controlled video processing/deflection IC TDA8885 which also controls sound. German stereo and Nicam is detected and processed by the MSP 3410 G. Dolby sound is processed by MSP 3452 G, virtual dolby by MSP 3411G, BTSC Stereo by MSP 3420G (or MSP 3440G ) IC by s option. All sound processors also control the sound volume, balance, tone and spatial stereo effect. The user-interface is menu based control system with cursor keys. Only for some functions the colour keys are needed: This means that some of the functions can also be operated from the local keyboard (i.e. Vol -, Vol +, P -, P+ and Menu). Teletext is done by the microcontroller on-chip teletext module.Fastext/Toptext(8page),One page are optional.
2. SMALL SIGNAL PART WITH TDA8885
The TDA8885 combines all small signal functions required for a colour TV receiver.

stop at very weak input signals. The first PLL has a very high statically steepness so that the phase of the picture is independent of the line frequency. The horizontal drive signal is generated by an internal VCO, which is running at a frequency of 25 MHz. This oscillator is stabilised to that frequency by using the 12 MHz frequency of the crystal oscillator as a reference. The time-constant of the first loop can be forced by the IC-bus (fast or slow). If required the IC can select the time-constant depending on the noise content of the incoming video signal. The horizontal output signal is generated by means of a second loop, which compares the phase of the internal oscillator signal with the phase of the incoming flyback pulse. The time-constant of this loop is connected externally and can be used as input for a dynamic horizontal phase correction. To obtain a smooth switch-on and switch-off behaviour of the horizontal output stage the horizontal drive signal is switched-on and off via the soft-start/soft-stop procedure. This function is realised by means of a variation of the TON of the horizontal drive pulse. When the soft-start procedure is completed the horizontal output is gated with the flyback pulse so that the horizontal output transistor cannot be switched-on during the flyback time. An additional function low-power start-upfeature. For this function a supply voltage with a value between 3 of the IC is the and 5 V must be available at the start-up pin (required current 5 mA typical). When all sub-address bytes have been sent and the POR and XPR flags have been cleared, the horizontal output can be switched-on via the STB-bit (sub-address 24H). In this condition the horizontal drive signal has the nominal TOFF and the TON grows gradually from zero to the nominal value as indicated in the softstart behaviour. As soon as the 8 V supply is present the switch-on procedure (e.g. closing of the second loop) is continued. The presence of the 8 V supply voltage is indicated by the SUP bit in the IC -bus output byte 02. The circuit generates a vertical sync pulse. This pulse can be selected on pin 49 via the bits CMB1 and CMB0. In the 100 Hz input processor versions the vertical sync pulse is available on pin 63 and the horizontal pulse on pin 56. Via the I C-bus adjustments can be made of the horizontal and vertical geometry. The vertical sawtooth generator drives the vertical output drive circuit, which has a differential output current. For the E-W drive a single ended current output is available. A special feature is the zoom function for both the horizontal and vertical deflection and the vertical scroll function. When the horizontal scan is reduced to display 4 : 3 pictures on a 16 : 9 picture tube an accurate video blanking can be switched on to obtain well-defined edges on the screen. Overvoltage conditions (X-ray protection) can be detected via the EHT tracking pin. When an overvoltage condition is detected the horizontal output drive signal will be switched-off via the slow stop procedure but it is also possible that the drive is not switched-off and that just a protection indication is given in the IC-bus output bytes. The choice is made via the input bit PRD. When PRD = 1 and an overvoltage is detected the drive is switched-off and the STB bit is set to 0. Switching on of the drive is only possible when the XPR flag is cleared. The IC has a second protection input on the j2 filter capacitor pin. When this input is activated the drive signal is switched-off immediately and switched-on again via the slow start procedure. For this reason this protection input can be used as flash protection The drive pulses for the vertical sawtooth generator is obtained from a vertical. countdown circuit. This countdown circuit has various windows depending on the incoming signal (50 Hz or 60 Hz and standard or non-standard). The countdown circuit can be forced in various modes by means of the IC-bus. During the insertion of RGB signals the maximum vertical frequency is increased to 72 Hz so that the circuit can also synchronise on signals with a higher vertical frequency like VGA. To obtain short switching times of the countdown circuit during a channel change the divider can be forced in the search window by means of the NCIN bit. The vertical deflection can be set in the de-interlace mode via the IC bus. 2.5. Chroma and Luminance processing The circuit contains a chroma bandpass and trap circuit. The filters are realised by means of gyrator circuits and they are automatically calibrated by comparing the tuning frequency with the reference frequency of the decoder. The luminance delay line and the delay for the peaking circuit are also realised by means of gyrator circuits. The centre frequency of the chroma bandpass filter is switchable via the IC-bus so that the performance can be optimised for front-end signals and external CVBS signals. During SECAM reception the centre frequency of the chroma trap is reduced to get a better suppression of the SECAM carrier frequencies. 2.6. Colour Decoder The colour decoder can decode PAL, NTSC and SECAM signals. The internal clock signals for the various colour standards are generated by means of an internal VCO, which uses the 12 MHz crystal

frequency as a reference. Under bad-signal conditions (e.g. VCR-playback in feature mode), it may occur that the colour killer is activated although the colour PLL is still in lock. When this killing action is not wanted it is possible to overrule the colour killer by forcing the colour decoder to the required standard and to activate the FCO-bit (Forced Colour On) in subaddress 21H. The IC contains an Automatic Colour Limiting (ACL) circuit which is switchable via the IC-bus and which prevents that oversaturation occurs when signals with a high chroma-to-burst ratio are received. The ACL circuit is designed such that it only reduces the chroma signal and not the burst signal. This has the advantage that the colour sensitivity is not affected by this function. The SECAM decoder contains an autocalibrating PLL demodulator which has two references, viz: the divided 12 MHz reference frequency of the crystal oscillator which is used to tune the PLL to the desired free-running frequency and the bandgap reference to obtain the correct absolute value of the output signal. The VCO of the PLL is calibrated during each vertical blanking period, when the IC is in search or SECAM mode. The reference frequency of the colour decoder is fed to the Fsc output (pin 49) and is used to tune an external comb filter. The base-band delay line is integrated. The demodulated colour difference signals are internally supplied to the delay line. The colour difference matrix switches automatically between PAL/SECAM and NTSC, however, it is also possible to fix the matrix in the PAL standard. 2.7. PICTURE IMPROVEMENT FEATURES In the TDA 8885 series various picture improvement features have been integrated. These features are: -Video dependent coring in the peaking circuit. The coring can be activated only in the low-light parts of the screen. This effectively reduces noise while having maximum peaking in the bright parts of the picture. -Colour Transient Improvement (CTI). This circuit improves the rise and fall times of the colour difference signals. The function is realised by using delay cells with a length of 300 ns. -Black-stretch. This circuit corrects the black level for incoming video signals, which have a deviation between the black level and the blanking, level (back porch). The time constant for the black stretcher is realised internally whitewith sufficient contrast values -Blue-stretch. This circuit is intended to shift colour near towards more blue to obtain a brighter impression of the picture -White-stretch. This function adapts the transfer characteristic of the luminance amplifier in a nonlinear way dependent on the picture content. The system operates such that maximum stretching is obtained when signals with a low video level are received. For bright pictures the stretching is not active. -Dynamic skin tone (flesh) control. This function is realised in the YUV domain by detecting the colourss near to the skin tone. The correction angle can be controlled via the I2 C-bus. 2.8. RGB output circuit and black-current stabilisation This IC has a very flexible control circuit for RGB input signals, which has the following features: Including 3 RGB input, one is dedicated for OSD signals one for scart1,the other one is for RGB applications. The RGB-1 input which is intended for OSD signals and which can be controlled on contrast and brightness. By means of the IE1 bit the insertion blanking can be switched on or off. Via the IN1 bit it can be read whether the insertion pin has a high level or not To obtain an accurate biasing of the picture tube the Continuous Cathode Calibration system has been included in this IC. Via the I2 C-bus a black level offset can be made with respect to the level which is generated by the black current stabilisation system. In this way different colour temperatures can be obtained for the bright and the dark part of the picture. The black current stabilisation system checks the output level of the 3 channels and indicates whether the black level of the highest output is in a certain window (WBC-bit) or below or above this window (HBC-bit). This indication can be read from the I2 C-bus and can be used for automatic adjustment of the Vg2 voltage during the production of the TV receiver. The control circuit contains a beam current limiting circuit and a peak white limiting circuit. The peak white level is adjustable via the I2 C-bus. To prevent that the peak white limiting circuit reacts on the high frequency content of the video signal a low-pass filter is inserted in front of the peak detector. The circuit also contains a soft-clipper, which prevents that the high frequency peaks in the output signal become too high. The difference between the peak white limiting level and the soft clipping level is adjustable via the I2 C-bus in a few steps.

CIRCUIT DESCRIPTION

(Refer to the Schematic Diagrams while reading this description) A) POWER SUPPLY
The chassis incorporates a Motorola switch mode power supply using a MC44608 regulator controller IC. The circuit provides power to the receiver in both stand-by and normal operation modes. The DC voltages required at various parts of the chassis are provided by an SMPS transformer controlled by the IC MC44608, which is designed for driving, controlling and protecting switching transistor of SMPS. The transformer produces 150V for FBT input, +/-14V for audio output IC, S+3.3, S+5V , +5V, +3.3V for controller and MSP and 8V for TDA8885. START UP The switch on the mains supply is fed through the mains filter network L107 and L108 , the surge limiter resistor R100 , the bridge rectifier diode D132, and reservoir capacitor C116, producing approximately 310Vdc to feed the switching MOSFET Q102 via the primary winding of TR101 pins 3 and 5. This process occurs in models without PFC ( Power Factor Correction ) circuitry. In models with PFC, the PFC circuitry based on the Motorola IC MC33260 is also effective and an approximately 380Vdc is produced to feed the switching MOSFET Q102. The MC33260 is a controller for Power Factor Correction pre-converters meeting international standard requirements in electronic ballast and offline power conversion applications. Designed to drive a free frequency discontinuous mode, it can also be synchronised and in any case, it features very effective protections that ensure a safe and reliable operation. The voltage to run the switching MOSFET Q100 is fed through L102 coil and this MOSFET runs MC33260 to run the PFC circuitry. Start up resistor R101 feeds from a 500V coming from the mains through the adder diodes D104, D135 to pin 8 of IC106 (MC44608), the IC uses 9mA current source and connects it internally to VCC at pin6 allowing a rapid charge enough for start up. Then IC106 responds with the oscillator starting to oscillate at a 40khz frequency fixed by the IC manufacturer. The IC then produces, pulse width modulation pulses, at this frequency on pin 5 to drive the base of the switching MOSFET Q102, that will then switch current on and off through the primary of TR101, which will in turn provides voltages in the secondary windings. The secondary winding voltages being proportional to the length of time that Q102 is turned on in each cycle. The voltage produced between pins 8 and 9 of TR101 is rectified by D105 developing approx. 12 volts on C110, which takes over from the start up resistor to supply pin 8 of IC106. This voltage is also used for Demag. pin (pin 1) of IC106 and VCC pin ( pin 8 ) of IC 107 ( MC33260 ). The Demag. pin at pin1 of IC106 offers 3 different functions: Zero voltage crossing detection (50mV), 24mA current detection and 120mA current detection. The 24mA level is used to detect the secondary reconfiguration status and the 120mA level to detect an Over Voltage status called Quick OVP.

MODE TRANSITION This chassis automatically selects stand-by mode when switched on.(For some special models this case is changed by software, according to the customer requests, such that TV selects the mode which was selected when the TV is turned off, whether directly power-off or first stand-by then power-off) The concept IC MC44608 is designed to detect the transitions between the stand-by and normal mode and to manage each mode in an optimal way. In stand-by, the device monitors a pulsed mode that enables to drastically reduce the power consumption. The LW latch is the memory of the working status at the end of every switching sequence. Two different cases must be considered for the logic at the termination of the SWITCHING PHASE: 1. No Over Current was observed 2. An Over Current was observed These two cases correspond to the two signals NOC in case of No Over Current and OC in case of Over Current. The effective working status at the end of the ON time memorised in LW corresponds to Q=1 for no over current, and Q=0 for over current. To enter the standby mode, secondary side is reconfigured using Q107 loop. This starts with the micro-controller pin 27 becomes high; as the standby port becomes s high Q516 conducts and Q105 becomes off, then Q107 conducts and the high voltage output value becomes lower than the NORMAL mode regulated value. The shunt regulator IC116 is fully OFF. In the SMPS standby mode all the SMPS outputs are lowered except for the low voltage output that supply the wakeup circuit located at the isolated side of the power supply. In that mode the secondary regulation is performed by the zener diode D123 connected in parallel to the TL431. The secondary reconfiguration status can be detected on the SMPS primary side by measuring the voltage level at pin8 of TR101. In the SMPS standby mode the 3 distinct phases are: The SWITCHING PHASE: Similar to the Overload mode. The current sense clamping level is reduced. When VCC crosses the current sense section, the C.S. clamping level depends on the power to be delivered to the load during the SMPS standby 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 STARTUP PHASE is similar to the Overload Mode. The MODE latch remains in its set status (Q=1). The SWITCHING PHASE: The Standby signal is validated and the 200uA current comes out of the Current Sense pin 2.
SMPS SWITCH OFF When the mains is switched OFF, so long as the electrolytic 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 VCC voltage is also reduced. When VCC is less than 6.5V, the SMPS stops working.

inverted for this IC, is fed from pin63/64 of IC200. The outputs of IC600 are used for vertical deflection.
B.C.L CIRCUIT (BEAM CURRENT LIMITER) Beam current limiting is employed to protect the circuitry in the receiver, the CRT and to prevent excessive X-ray radiation in fault conditions. The current drawn by the CRT is monitored by the current drawn through the winding of the fly-back transformer that produces the EHT for the CRT anode. The end of the winding (Pin 10) is returned to IC200 Pin 34, here according to the beam current info, low or high, brightness and contrast of the picture is set not to load the CRT with edge and maximum ratings. The beam current drawn by the CRT passes through Q602 and develops a voltage on the collector proportional to the current (V=IxR). The voltage on the collector will vary depending on the beam current being drawn reducing the brightness and contrast of the picture. If the voltage is sufficiently negative (indicating very high excess beam current) the output will be reduced, reducing the picture brightness and contrast.
