The regulations and safety instructions shall be valid as provided by the "Safety" Service Manual, part number 72010-800.00, as well as the respective national deviations.

Safety Advice

The X-radiation developing in the sets conforms to the X-radiation Regulations (January 8, 1987), issued by the Physikalisch-Technische Bundesanstalt (federal physiotechnical institution). The high tension for the picture tube and thus the developing Xradiation depends on the precise adjustment of the +A power supply. After every repair of the power supply unit or the horizontal deflection stage it is imperative that the EHT for the picture tube is checked and re-adjusted if necessary. To avoid consequential damages to the chassis or the picture tube the integrated protective circuits are allowed to be put out of operation only for a short time. When replacing the picture tube use only the types specified in the spare parts lists.

TUNING IN

TUNING

Your TV set can memorise 99 different channels. During channel tuning any connected satellite receiver or video recorder should be switched to standby. To tune in different channels, follow the instructions below.

Step 1 Press TUNE on the remote control.

A tuning bar will appear. Step 2

Press P+ for approximately one second. The set will scan up through the available channel

frequencies. A cursor moves slowly up the bar until

'S'

a channel is found. The S will now flash on and off. If you do not wish to store the channel, press P+

again until a required channel is found. Step 3

Press STORE to memorise the channel. The programme setting PO1 will now flash on and off.

Step 4 Decide which channel number you want to allocate the channel to e.g. BBC1 = 1. Press the appropriate number e.g. 1.

FINE TUNING

After following the TUNING instructions you should have a clear picture on all channels (subject obviously to the reception quality of the incoming signal). If any channels are not to the standard you would expect, fine tuning may sometimes improve the picture quality. To fine tune follow the steps below:

Step 1 Select the channel to be tuned. If the tuning bar is no longer on screen press TUNE. If it is, move onto step 2.

Step 2 Press HOLD very briefly. An X will appear besides the programme number to indicate that fine tuning has been selected.

Step 3 By briefly pressing P+ or P-, fine tune the picture.

Step 4 When the best possible picture has been achieved, press STORE twice to memorise the settings.

Step 5 To return to normal television viewing press TV.

Note : the X symbol means that the Automatic Frequency Control (AFC) has been switched off. Channels stored with the X displayed may drift off tune and therefore fine tuning should only be used if absolutely necessary.

Step 5 Store the setting by pressing STORE.

The channel is now stored against the chosen channel number. The tuning bar will still be on screen and the S will still flash.

Now tune the remaining channels. Repeat steps 2, 3, 4 and 5 until all channels are tuned in.

To exit the tuning screen press TV.

TUNING INTO A VIDEO RECORDER, SATELLITE RECEIVER OR GAMES CONSOLE

If connecting a video recorder, satellite receiver or games console to the television set via the scart sockets (see page 3 and 14), press 0/AV on the remote control. Alternate presses of 0/AV selects between the AV inputs, AV1 and AV2.

If making the connection via the television sets aerial,

select channel 99 as the dedicated channel by pressing 9 twice.

ST 03 Circuit Description

Circuit Description

1. Power Supply

The power supply is a conventional off line, isolated switch mode system. AC line voltage is applied to the circuit via switch fuse and the main input RFI filter. The degauss coil supply is taken off after the filter then the AC is rectified through a bridge circuit comprising D100 to D103. After filtering by C103 and C104 the DC is now fed to T100 switch mode transformer. TR100 is the switching transistor and it, in turn, is driven by the UC3844 IC100 which is a PWM (Pulse Width Modulation) control IC. In the basic chassis, the UC3844 is run as a fixed frequency PWM controller, the frequency being governed by R105 and C107.

1.1 HT Adjustment

VR100 is used to set the +B, this varies the output voltage by controlling the feedback voltage to the IC100. The +B rail is the line measured when this control is used. This line is set in accordance with the CRT that is fitted. When this rail is set then any variation in power demand by the receiver will be reflected in the feedback winding which, in turn, will appear as an error voltage on IC100-(2). This error voltage will, in turn, vary the PWM output to the switching transistor which, in turn, will maintain the output voltage constant.

1.2 Over Current Protection

The power supply is totally overcurrent protected by sensing the current through the switching transistor. The combination of R114, R113, D112, D113, R112 and C113 all act to provide conditioning of the sensing voltage for the IC100 current sense input. As current flows across TR100 collector-to-emitter junction (source drain for stereo) a voltage proportional to the current is produced across R114 and R113. This voltage is fed to Pin 3 current sense pin of IC100. When the predetermined threshold voltage is reached because of excess current drawn IC100 limits the current to protect the PSU and other circuits. After a period of time it will try to restart, if the fault has not cleared then it will shut down again. D112 and D113 are there to prevent the voltage developed rising to an unacceptable level on the sense pin of the IC. R112 and C113 provide a degree of filtering of the sense waveform. T100 also provides the isolation from the AC line to the chassis of the TV. All secondary supplies are isolated so that the main - and external connections are at ground potential, therefore, safe to the user. Warning! The heat sink on TR100 is live.

1.3 Supply Regulation

The 5V supply for some of the main ICs of the system is supplied from the secondary winding of T100, the 9V output is fed into a fixed 5V voltage regulator. The 33V tuner tuning volts is derived from the +B line using a band gap close tolerance shunt regulator D120. R115 and C114 are isolation components linking the non-isolated to the isolated side of the chassis for RFI and electrostatic purposes.

2. Tuner and Demodulator Circuits

The tuner TUN600 can be one of two models depending on what transmission system is being viewed. For the U.K. using PAL System I the tuner is a Salcomp 1590R. For all other European PAL and SECAM systems the tuner is a Salcomp 1490R. Both tuners are pin for pin compatible, the only difference is that the 1590R is UHF only and the 1490R is a multi band tuner. Both tuners are voltage synthesis types and tuning voltage is controlled by the system microcontroller IC500. AGC control of the tuner is determined by the demodulator IC400.

2.1 SAW Filter Options

The IF output of both types of tuner is a balanced output and is fed into a number of balanced input saws - SAW450, SAW600 and SAW601. As to which or how many saws are fitted is determined by the options fitted and the system to be received. In the stereo chassis SAW 600 is fitted. However, this can be a different type of SAW depending on the system being received. A system table is presented on the circuit diagram giving the specific type of SAW to be fitted in the 601 position for each system.

2.1.1 SECAM L/L (option) If the chassis is fitted with SECAM L/L the addition of SAW450 is

required for the sound.

2.1.2 Stereo SAW

Should the full stereo option be required then SAW601 is replaced with SAW600 and SAW450 stays as it is if SECAM L/L is also required.

2.2 Vision IF Demodulator

Taking the basic case the outputs from whichever SAW600 or 60 is fed to the IF input of the demodulator IC400-(19), -(20) which is an STV8224. Under most applications there is only one adjustable component in this circuit and that is L401 tank coil. However, when SECAM L/L option is required an additional trim capacitor is required along with R416, C412, D532, R417 and R425. The incoming signal is demodulated in the STV8224. The demodulated video and intercarrier sound are then fed out on pin 3 STV8224. The combined signals are fed into the filter circuits for separation of sound and video. The separation is achieved by the use of ceramic filters. CF400 and CF401 are the filters that perform this task.

2.3 Dual System Sound Options

It will be noted that there are two ceramic filters, CF400 and CF401. Both sets are required if dual system operation is required. Details are to be found in the system table on the diagram for each option. The separated signals are then fed back into the IC400 where the sound is demodulated and the audio processed. The video and audio are then routed by the internal switching of IC400. The routing is controlled by the microcontroller. The external video and audio from the Peri connector are also fed into this IC.

2.4 Tuner AGC Control

The STV8224 also performs AGC control for the tuner. The operational threshold for AGC action is controlled by the microcontroller, the threshold level is set up on IC400-(24).

2.5 SECAM L/L’ Vision IF (option) In the event of SECAM L/L’ option being required, then additional

IC450 needs to be fitted as does SAW450. This is in order to demodulate the AM sound of SECAM L/L system. Audio switching is then re-routed between IC450 and IC400, this is all done under the system microcontroller software in IC500. The switching network comprising TR450, TR451, TR452, D450 and D451 is for the purpose of switching the SAW transducer with variation in band switching. Because the sound and vision carriers are transposed between Band 1 and Bands III, IV and V, then the balanced IF output has to be switched to the right transducer on SAW450. The switching is again controlled by the system microcontroller IC500. The transducer that is not being used is short circuited by its respective diode.

3. Peritel Output

The video out to the Peri connector is taken off before the filtered signal is fed back into IC400. It is then fed to a buffer circuit TR700 and then to pin 19 of the Peri connector.

4. Video Chroma Processing

IC800 is the video and chroma processing circuit. All controls are totally under software control. Customer controls can be adjusted from the front panel. The raster correction controls are only accessible in factory set-up and troubleshooting mode set by the system microcontroller. The customer controls are accessed in this mode, or by the conventional remote control. The composite video is fed into IC800-(2). Separation of luma and chroma signals is carried out internally by the sampled data method using clocks generated by the external crystal. This method is used for all decoding processes in the chip. The sample clock is phase locked to the subcarrier for correct colour ident.

5. Delay Line

The sample component chroma signals are now fed to a digital, 1 picture line length delay line. The same sample clock is fed to the delay line IC801 as is fed to the IC800 so that phase relationship is maintained within the whole system.

5.1 RGB Matrix and Sync Separator

After passing through the delay line it is returned to IC500-(26), -(27) and then mixed with the luma and fed into the matrix circuits to produce the RGB output. The luma signal is also fed through a short delay line

GRUNDIG Service 2 - 1

Page 10

Circuit Description ST 03

which is integrated on to the IC800. The sync separation and time base circuits are also integrated on to this chip. Incoming video is stripped of its line and field sync pulses. The horizontal and vertical syncs are then derived from the composite sync waveform.

6. Time Base Generator

The line sync is fed to the line time base generator circuit. The line time base is derived from the master clock oscillator and divider circuit. The line pulses from the divider are fed into both PLL circuits along with the sync and flyback pulses. These combine together to produce the line drive for the line output circuit. Two PLL time constants are used to give good lock for both fixed, gen-locked syncs, such as from terrestrial transmission and from weak or variable sync such as VCR. All controls for the line time base generator are integrated and are accessed via the I

C bus under microcontrol from IC500. These are set

up in the factory by a test software.

6.1 Vertical Time Base

The vertical time base is again generated on chip by the use of the master clock in conjunction with the separated field sync. The divider circuit count is controlled by the sync pulse. The counter produces the pulses to generate the vertical ramp which is in turn fed to a buffer and then fed out to the field output circuit. In the event of no valid sync being present then a direct injection mode is used to continue the function of the ramp generator. This direct mode then enables vertical scan to be maintained in the event of no signal being present.

7. RGB Drivers

The RGB video signals are fed out on IC800-(17), -(18), -(19). These signals are then buffered by the emitter follower circuits TR801, TR802 and TR803 before being fed to the tube base panel. External RGB signals are also able to be fed into this IC on pins 22, 23 and 24. These pins are normally fed with RGB levels of 700mVpp signals for nominal display. The choice of display is determined by the switch pin on IC800-(21). This is controlled by the output of the teletext chip blank signal or the blanking signal from the microcontroller for on screen graphics display or the PERITEL pin 8.

7.1 Auto Grey Scale Tracking

The system also incorporates an automatic grey scale tracking system. This removes the need for manual adjustments to set up background luma levels in high-light and low-light areas on CRTs. For correct tracking the auto grey scale works on the principal of taking measurements of the dark current during the field blanking period and also inserting a peak white signal in that period and setting those thresholds to control the output stages of the chip. This ensures that the tube characteristics are constantly being matched by the video output so that grey scale and picture colour integrity is constantly maintained.

7.2 Beam Limiter

The RGB output gains are also affected by the beam limiter circuit on IC500. This is to prevent the tube from being damaged or its life expectancy being shortened by excessive beam current. The sensing of the beam current is performed at the bottom end of the DST secondary supplying the EHT focus and G2 voltages to the tube. The reference point is pin 7 on the DST, this current is sensed as a change in voltage developed across resistors and fed to the beam limit sense IC800-(9). This voltage is measured against a reference which represents maximum beam current. When the sensing level exceeds the reference then the gain on RGB output amps is reduced, thereby reducing the beam current. Saturation control, brightness and contrast are adjusted via the remote control but the nominal levels are preset in the factory by the I

C bus using the microcontroller and test software.

8. System Microcontroller (IC500)

The ST6365 is a dedicated microcontroller for TV control applications. It has such features as dedicated voltage synthesis tuning control, AFC control and on-screen graphics display generator. Also it has a dedicated infrared remote control serial data input. This microcontroller has a dedicated I

C port for communication to other controllable ICs. The controller clock frequency is 8MHz and this clock speed is achieved by connecting an 8MHz ceramic resonator across the oscillator pins 31 and 32 with two 100pF capacitors, C507 and C508, to ground from each pin. The timing for all functions performed by the microcontroller including I

C bus are taken from this clock.

8.1 Voltage Synthesis

The on-chip voltage synthesis tuning peripheral has been integrated to allow the generation of a tuning reference voltage. The peripheral is composed of a 14 bit register that represents the tuning voltage at pin 1. This voltage is generated using pulse width modulation and bit rate multiplier techniques. The 14 bit counter gives 16384 steps which allow a resolution of approximately 2mV over a tuning voltage range of 32V. Coarse tuning is achieved by PWM of the 7 most significant bits of the counter, whilst fine tuning is achieved by BRM (Bit Rate Multiplication) of the 7 least significant bits of the counter. The resultant digital pulse train is fed into the base of TR410. This inverts the pulse train which is then fed into the 3 stage integrator which integrates the pulse train into a DC voltage.

8.2 AFC Control

The output of the voltage synthesizer can be changed either by the remote control or the local keyboard. The tuner oscillator is kept on frequency by the application of AFC. The AFC acts on the voltage synthesizer via a feedback path. The AFC is generated by IC400. This voltage is fed back to the AFC pin 9 on the controller. As the tuner oscillator drifts either up or down so the signal applied to IC400 deviates from the optimum. As a result an error voltage appears on IC400-(2). This voltage can be either positive or negative with respect to the optimum voltage. This error voltage is fed to pin 9 of the microcontroller. This voltage is then digitized. If the digital value is optimum then no change is made to the synthesized digits. If the digital value is either side of optimum, then the resultant AFC value is either added to or subtracted from the synthesizer value.

8.3 Analog Controls

Pins 2 and 5 on the microcontroller are PWM D-A converters. However, these are only 6 bit resolution which is perfectly acceptable for the analog functions they perform. The D-A on pin 2 is used as the electronic volume control for the sound. The D-A on pin 3 is used for the multi-level voltage control for audio and video switching of IC400 and IC450. The D-A on pin 4 is used to produce the threshold level for the AGC to the tuner. The final D-A on pin 5 is as yet uncommitted. The microcontroller has 3 I/O ports as well as the dedicated peripheral pins, some of the I/O ports also have dedicated functions and are listed as their dedicated function, i.e. the AFC on pin 9 is bit 3 of port B.

8.4 Key Pad Interface

Bits 0-2 and bits 4-5 of port B provide the matrix for the crosswire keypad.

8.5 Sync Detector/Mute Control

Bit 6 of port B is a sense pin which mutes the sound when text is displayed and incoming signal is lost. Normally the microcontroller will mute the sound when the aerial is removed or tuning is off station because it detects no line lock coincidence. However, in out-of-hours sync mode, the text chip set detects lack of sync coincidence and mutes the sound. Bit 0 on port A senses the status of pin 8 on the peri connector for switching video and sound to incoming signals on the peri connector.

8.6 Peritel Monitor/OSG Control

Bit 1 on port A monitors the blanking signal on pin 16 of the peri connector and also the blanking signal from text and OSD sources. Bit 2 of port A acts as the control line for the switch that acts on SAW450 as described in section 2. Bit 3 is usually linked to ground, however for System PAL BG/SECAM L/L’ this link is omitted.

8.7 Band Switching and LED Driver

Bits 4 to 6 of port A are the band switching outputs which drive the band switches. Bit 7 of port A is connected to the LED D500. Pins 22 and 25 are OSG display pins whilst pins 26 and 27 are the sync input pins. Pin 33 is the hardware power-on reset. Pin 34 is the SECAM L/L SAW selector switch. Pin 35 is IR input line. Pin 36 is BG/DK system select.

8.8 Standby Control/ Sound Mute

Pin 37 is available as a standby line for external use. In normal standby, the controller shuts down all circuits that provide drive to output stages, thereby placing the system in quiescent current consumption mode. Pin 39 is the sound mute output which drives the sound mute transistor TR5 and TR7. Pins 40 and 41 are the dedicated I

C bus.

9. Output Power Stages

This section describes the power output stages for video, audio, line and field scanning system.

9.1 Field Output (IC200)

The TDA8170 IC200 is a power output amplifier designed to drive the vertical scan coils on the CRT yoke. The saw-tooth waveform is fed into pin 1 from pin 7 of IC800. Internal to IC200 is the flyback generator. The flyback generator produces a pulse equivalent to the field blanking period during which time no visible video appears on the screen. The saw-tooth voltage waveform is converted to a current waveform that drives the field scan coils. The flyback part of the waveform is also used to generate the vertical sync pulse for the OSD. The circuit R207, D202 and R208 slice the waveform to give the vertical sync pulse and to limit it to a voltage of no greater than 4.7V.

9.2 Line Output Stage

The line output stage has to provide a number of things for the system. Firstly, it provides the power and the waveform to drive the horizontal scan coils on the CRT yoke. Secondly, it provides the voltages for the tube, EHT final anode drive, focus voltage and G2. Thirdly, it provides two secondary low tension voltages, 15V and 26V, and after passing through a fixed voltage regulator, IC300, 12V. Fourthly, it provides on the primary side of the transformer the 150/180V supply for the tube base video output amplifiers and, finally the voltage for the heaters on the CRT of around 6.3V. The tuning capacitor C300 is selected by the type of tube fitted as are the correction circuits L300, L301, R300 and R301.

9.3 Line Driver

The line drive signal from IC800 is first clamped by D804 then inverted by TR800. The resulting waveform is fed to TR301 line driver stage. The drive is applied to the line output transistor TR302 across the line driver transformer T311. TR302 drives both the diode split transformer T300 and the line scan coils connected to PL351. The field coils are also connected to PL351.

9.4 12V Regulator Circuit

The 15V generated off the low side secondary of the diode split LOPT is used in the beam current sensing circuit prior to it being fed into the 12V fixed regulator IC300. From the primary side of the diode split there is a circuit which is used to produce a low level line flyback pulse. This is the circuit around TR300. The flyback pulse is used by the IC800 for synchronization in PLL’s and also for the line blanking during video for line flyback period. Also from this circuit is supplied the horizontal sync pulse for the OSD of the microcontroller.

9.5 Flyback Pulse Circuit

The flyback pulse is fed into TR300 via two high value resistors R302 and R303. The high values are because at the take-off point the flyback pulse could be in excess of 1kV. The capacitor C306 is a speed-up capacitor to improve turn on and off characteristics of TR300. The diode D305 clamps the incoming flyback pulse to 5V so that the output at the emitter of TR300 does not rise above 5V and that the base of the transistor is not spiked by excessive transient voltages.

10. Video Output Stages

The video output transistors TR900, 901, 902 are driven directly from the buffer transistor circuits at the output RGB of IC800. The gain of the stage which determines the video voltage swing applied to the tube cathode is set by a register in IC800. The actual gain control known as contrast is also a register in IC800 as is the brightness control. The capacitors connected across the emitter resistor is to give a little extra gain at the HF end. The transistors TR903, 904, 905 are the dark/light current sense transistors and feed the dark current sense on IC800-(20) for auto grey scale.

10.1 Auto Grey Scale

When the video output transistor is driven with peak white which equals max. beam current then the voltage drop across the diodes increases thereby making a difference of potential between base and emitter causing the transistor to conduct. This produces an output by the collector proportional to the high beam current. As the output transistor

is turned off at black level, so the reverse happens with the sense transistors until we are left with a voltage that represents the dark tube leakage current which is a dark reference current for the tube.

10.2 Tube Base Interconnect

Connection to the tube base is via two connectors CN901 and CN902 for the main connectors, then by single connectors for the focus and G2. The final anode voltage is applied directly to the connection on the side of the tube bulb. The tag coating connection is made by a single tag to the tube base panel ground.

11. Teletext Options

The text chip-set being used is the Texas Instruments 2 chip Videotext decoder set. Depending on what system is required Eurotext or Unitext determines what IC650 will be. A table of components that change are shown in the "Text Table" on the schematic. IC651 is the data slicer and timing signal generator. The timing signals are all generated with respect to the master clock which is derived from the crystal XT650. The value of this crystal is twice the data rate of the text signal

13.875MHz. This clock is synchronized to the clock run-in signal at the front of the data packet. The data is then output to IC650 along with data clock and the other timing signals. IC650 then decodes the data and produces the text display for the screen. If the TV signal is present then the whole thing is locked to the incoming sync signal. If the TV signal is not present then the system generates its own sync so that text stored in memory can still be displayed in a locked form. All commands and customer selection are engaged via the I is attached to the microcontroller I The RGB outputs are then fed to the input for external RGB on IC800. The control signal for the blanking function is taken to switch input of IC800-(21). For Eurotext the outputs are directly fed to IC800 whilst buffers are used for Unitext.

12. Power Supply to MSP 3400/3410

Power is supplied to the MSP from pin 4 of plug PL102. This is an 8V supply derived from the chopper transformer and is therefore available when the receiver is in standby. The 8V supply is regulated to 5V by IC3 and applied to the MSP via RFI filters (L2, CT2 and L4, CT4) to pins 18 and 57 of the MSP. The 8V is supplied to pin 39 via the RFI filter L3, CT3. The reason the 8V line operates in standby is because this locks the internal audio switches into pre-set positions when the 5V voltage is removed so as to reduce the standby power. TR4 is open circuit during standby.

12.1 MSP Operation

The ITT MSP3410 decodes FM, dual-channel and NICAM sound; the MSP3400 does not do NICAM. The intercarrier input is applied to pin 58 for all systems except France where an additional filter may be required. The input is then to pin 60. The MSP is controlled by the clock and data lines (I internal clock from the crystal on pins 62, 63 at 18.432MHz. Reset components are on pin 24. Note there are no adjustments on the MSP as all processing is done digitally. Note, the volume control is now an

C operation as is treble, bass and balance.

13. Second Peritel and Mute Circuit

Video from the second peritel is supplied from pin 20 of Peritel 2. This is then buffered by TR20 and applied to IC4-(1). IC4-(2) carries video derived from the tuner and IF amp. The switch position is controlled by IC4-(10). The microcontroller (pin 5 DA4) controls the switch position. The output of IC4 (pin 15) is applied to the times-2 gain stage TR1, TR2 and out to Peritel 1, input of IC400 -(10) and so to the picture tube if there is no input from Peritel 1. Mute Circuits TR5 and TR7 mute the loudspeaker channels. TR12, 13, 10 and 11 mute the two Peritel audio outputs. The mute circuit is driven by port zero and port 1 (pins 4 and 5) of IC1. Pin 5 mutes the speaker channel and pin 4 the Peritel channels. TR9 detects when the receiver is switched off and mutes all audio outputs.

14. Audio Amplifier

The audio amp generates 6+6 watts of RMS power into 8R speakers. The power is derived from a 21 volt winding on the chopper transformer.

C) from the microcontroller. The IC generates an
