The power supply is a conventional flyback power transfer isolated switch mode system. AC line voltage is applied, via an isolating double pole switch, a fuse and RFI filter, to the degauss coil and bridge rectifier. Diodes D100-D103 form a full wave bridge rectifier with the resultant DC voltage filtered by C103, C104 [and C134] and fed to the switch mode transformer T100. IC100 controls the switch mode operation and supply regulation as a fixed frequency pulse width modulation drive to T100 via transistor TR100. R105 and C107 set the oscillator frequency.
C123
Regulation is determined by an error voltage tap off of the transformer T100, pin 11, via diode D105 and VR100 to pin 2 of IC100. Within IC100 this error voltage is compared to a fixed reference and the pulse width output on pin 6 is varied accordingly. If the output voltage falls due to increased load then the 'on' time of TR100 is increased to compensate by varying the PWM signal on its base. Note that the heatsink of TR100 is not isolated and is at a high voltage.
The power supply is overcurrent protected by IC100 sensing the excessive current flowing through TR100. R113, R114, D112, D113, R112 and C113 form a network to set the sense current value. A voltage proportional to the current flowing through TR100 is developed across R113 and R114 in parallel. D112 and D113 limit the voltage applied to the IC sense pin 6. R112 and C113 filter out noise and spikes to prevent erroneous operation. In the event of an over current situation and the sense threshold is exceeded then IC100 will remove the PWM drive to TR100. After a short period of time the drive is reinstated and if the fault has not cleared it will shut down again.
A secondary supply is 110V for the line output stage, this is regulated to 33V across across a close tolerance shunt regulator, D120. A 9V supply is produced by D114/ C115 this is regulated to 5V by IC102
Control of electrostatic discharge and RFI is done by the isolating components C114 and R115.

The TDA8170 IC200 is a power output amplifier designed to drive the vertical scan coils directly with a sawtooth current signal. A sawtooth voltage waveform is fed into pin 1 from pin 7 of IC800. An internal flyback generator supplies a flyback pulse on pin 3, this is limited to 4.7V by R207 and D202 and is used as the vertical timing pulse for the on screen display and as a blanking pulse. C201 and D200 form a voltage doubler for the supply to IC200's output drive circuit.
The line drive signal from IC800 is firstly clamped by D804 then inverted by TR800. the resulting drive signal is fed to TR301 line drive stage. Line drive is then fed to line output transistor TR301 via the inverting transformer T311. TR302 drive both the split diode transformer T300 and the line scan coils on PL351. Line Output stage
The line output stage has to perform a number of functions for the system., firstly it provides power and the waveform to drive the horizontal scan coils on the CRT yoke. Secondly it provides high voltages for the tube EHT final anode along with focus and G2 bias. Thirdly it provides two secondary LT voltages, 15V and 26V and via regulator IC300 a further 12V supply. Fourthly it provides high voltage supplies 150/180V for tube base video amplifiers and also the tube heater supply. C300 is selected for the type of tube fitted as are the scan correction components L300, L301, R300 and R301. The 15V supply across C308 is used for bias for the beam current sensing circuit via R350 that is selected according to the tube used. Transistor TR300 is fed with a pulse from the primary of T300 via R302 & R303. Diode D305 clamps the level to 5V and prevents damage to TR300, from the emitter of TR300 horizontal pulses are utilised for line blanking, synchronisation in the line oscillator PLL and on screen display horizontal timina

TP401. Demodulated video signal with sound carrier. 2v/div and 20us/div
TP404. Signal on VIDEO A with colour bar input to the SCART connector, TV switched to AV. 0.5V/div and 20us/div
The Tuner can be one of two versions depending upon the transmission system. For the UK PAL I the tuner is a Salcomp1590R. For all other European PAL and SECAM systems the tuner is a Salcomp 1490R. Both tuners are pin compatible the difference being that the UK version is UHF only. For European systems the 1490R is a multiband tuner. Both tuners are of the voltage synthesis type with the tuning voltage being controlled by the system micro IC500. AGC control of the tuner is determined by the demodulator IC400.
On the 1490R tuner band switching is determined by the system micro and the interface transistors TR500/ 1/2. These transistors act a voltage switches controlled by the PA4, PA5 and PA6 ports of the system micro. SAW Filter options
Tuner If outputs are balanced and can be fed into a number of balanced input SAW filters, SAW450, SAW600 and SAW601. The number and type of SAWs fitted is determined by the system to be received. In the basic chassis SAW601 is fitted. However this can be a different type of SAW depending on the system being received. The later version of the NICAM stereo TV uses SAW600 and IC601 to filter out the 6.5Mhz NICAM carrier
IF outputs from the selected SAW filter are fed into pins 19& 20 of IC400, an STV8224 dedicated IC. In most cases the only adjustment is tank coil L401. However, when SECAM LL is used additional components around this section of circuit are fitted. Demodulated video and intercarrier sound are fed out on pin 3 of IC400. Filter circuits separate video and audio carriers using ceramic filters CF400 and CF401.
CF400 is the normal 6Mhz ceramic filter. CF401 and switching components are added for dual sound systems and CF400 or CF401 can be selected. Audio carriers are sent to input pin8 for demodulation. The video signal has the audio carriers filtered out and it is split into pin 10 of IC400 and out as Video-B to the Scart connector, after buffering by TR700. External video and Audio signals enter IC400 on pins 12 and 16 respectively. IC400 performs signal routing under the control of the system micro with audio out on pin 14 and video on pin11 as Video-A
The STV8224 also carries out the function of AGC control for the tuner. The threshold level is set up on pin 24 of IC400.
IC400 Pin4 is low for TV and high for external input. It can be forced to external by connecting Pin 4 to 11V via a 5K6 resistor
Internal audio is fed out from pin14 of IC400 to the audio power amplifier IC550. The volume level is set in IC400 by the micro controller operating on pin 13 of IC400.

TP503. IC500 Pin 35. I/R data from remote control.
The ST6365 is a dedicated microcontroller for TV applications. It has many features such as dedicated voltage synthesis tuning control, AFC control and an on screen graphics display generator. Also there is a dedicated IR serial data input port for remote control. An I2C bus is used to communicate with other controllable ICs. An 8Mhz ceramic resonator is connected to pins 31 & 32 with two 100pF capacitors, C507 & C508, for the main timing clock. All functions are controlled and timed from this clock. Local control via the key buttons is via the matrix on ports PB0/1/2/4/ 5
The tuning voltage is present on pin 1 as a pulse width modulator, it is inverted by TR410 to a 33V pulse width variable square wave. It is converted into a 0-33V ramp by a three stage integrator R505-R507 and C500 - C502. Within IC500 is a 14 bit counter giving 16384 steps that allow a resolution of 2mV over the 32V tuning range. Coarse tuning is achieved by pulse width modulation of the 7 most significant bits and fine tuning by Bit Rate Multiplication of the 7 least significant bits.
For channel selection purposes the output of the tuning voltage synthesizer can be changed by either the remote control or local keyboard. The AFC feedback control voltage is generated by IC400 and fed back to pin 9 of the controller. As the tuning oscillator drifts up or down an error voltage is developed on pin 2 of IC400. This error voltage can be negative or positive with respect to the optimum voltage, it is fed to pin 9 of IC500 and digitised. If the digital value is optimum then no change takes place. If the value is higher or lower than the optimum then the resultant error value is added to or subtracted from the value in the tuning voltage register. Port PB6 is a mute input and performs this function when text is displayed or when no signal is present to the text circuit and no sync coincidence takes place.
Port PA0 detects a signal on pin 8 of the SCART connector and switches to the incoming vision and sound. Port PA1 monitors the blanking signal on pin 16 of the SCART connector and also from text and its own OSD output. Port PA2 is the control line for SAW450 for Band switching
Ports PA4 to PA6 are the band switching selection
Port PA7 switches on LED500.
Pins 22-25 are the on screen display output RGB drives. Pins 26 & 27 are the sync inputs for the on screen display generator timing
Pin 33 is the hardware nower on reset.
Pin 34 is the SECAM detect switch.
Pin 35 is the IR input serial port.
Pin 36 is the BG/DK system selector switch
Pin 37 is available as a stand-by line for external use. In normal stand-by the controller shuts down all circuits that provide drive to output stages, thereby placing the TV in quiescent current consumption mode.
Pin 39 drive the sound mute transistor TR550. Pins 40 & 41 are the dedicated 12C bus

Internal adjustment, repairs or component replacement should only be carried out by qualified and skilled personnel. Persons utilising this service manual must have a basic knowledge of television receivers and their operation. It is assumed that such persons have an understanding of switch mode power supplies and can comply with current workshop practice relating to such power supplies and printed circuit boards and the danger of:-
This receiver operates on UK mains electricity supply of 240V AC 50Hz. The mains lead supplied with the receiver is fitted with a standard 13A UK plug (BS1363) fitted with a 3 amp fuse (BS1362).
Safety regulations demand that the receiver must be restored to its original condition in the respect of seals and power insulation and that safety components are replaced by original manufacturer's parts. Safety components are clearly marked upon the service manual by A.
The G1000 series TV's were manufactured by a factory in France. Spares are suplied by Grundig International or its distributors. As many different tubes were used these are not supplied as spares and in the event of a tube failure the whole TV may be replaced by the supplier as a spare part; check before advising the customer.
In early versions when fine tuning was used the software did not return to AFT mode and tuning drift occured. Retune the channels without entering the fine tuning mode.
Leakage in C816,817,818 may cause a blank screen, check DC levels.
White blank screen check 150/180V rail, Reduced width and twice line speed indicates a micro failure (IC500). NICAM. This service manual was produced for the standard mono chassis, NICAM was added later and not all of the information was available at that time. Apologies for any gaps in part numbers, where there is no part number a standard component may be used. Please ensure that safety components are always replaced by the original Grundig part.
While every car has been taken to ensure accuracy please accept my apologies for any errors that I did not spot. During production changes have been made to the printed circuit and components, mainly SM have been moved about. In particular three pin diodes have been changed to the cylindrical glass diode type of construction favoured by Grundig, Germany.

The text chip set is the Texas Instruments two chip Videotext decoder set Depending on what system is required Eurotext or Unitext determines what IC650 will be, with accompanying component changes. IC651 is the data slicer and timing signal generator. Timing signals are all generated with respect to the master clock that is derived from crystal XT650. At 13 875 MHz this is twice the text data rate.
The master clock is synchronised to the clock run-in signal at the beginning of each data packet. The resultant data is then outputted to IC650 along with the data clock and other timing signals. IC650 then decodes the data and produces the text display for the screen. If the TV signal is present the all of the timing signals are locked to the incoming syncs.
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 stable form. All commands and customer selection are transferred via the I2C bus from the microcontroller
RGB outputs are fed to IC800 in parallel with OSD and SCART inputs with the fast blanking signal to switch input pin 21 of IC800. For Eurotext the outputs are fed directly to IC800 whilst buffers are used for Unitext.

TP806. IC800 pin 20. Auto grey scale feedback signal.
IC800 is a complete Y/C processing circuit. All controls are software adjusted and stored in registers. Consumer adjustment is limited to the front fascia controls. Raster correction controls are only accessible in factory set up and trouble shooting mode set by the system microcontroller, also the consumer controls are accessed in the mode.
Composite video is fed in to pin 2 (VIDEO IN 2). Separation of luminance and chrominance 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 IC. The sample clock is phase locked to the subcarrier for correct colour ident. Delay Line.
Sampled chroma signals, designated R-Y and B-Y, are fed to a digital CCD delay line IC with an accurate delay of 1 picture line. CCD delay line clock is derived from the 17.7Mhz crystal XT800 and is phase locked to the colour signal. Two outputs of separated R-Y and B-Y are from pins 7 and 10 respectively.
RGB matrix and sync separator.
After passing through the delay line the colour component signals are matrixed with luminance to produce RGB outputs. Luminance delay is within IC800. Composite sync is stripped of the incoming video in a sync separator circuit within IC800, from these pulses the sandcastle waveform is constructed. Line syncs are fed to the line timebase circuits. Line time base is generated by a master clock oscillator which is phased locked to line syncs. Two phase locked loops are used with differing characteristics for broadcast signals and VCR replays. All controls for the line time base generator are integrated into IC800 and are accessed via the I2C bus under microcontrol from IC500. These are set up in the factory by test software.
Vertical timebase is also integrated into IC800. A divider counter is controlled by the field sync pulses separated from the video signal. This counter produces pulses that generate the vertical ramp. As the counter is driven by a clock then in the event of no signal it is able to count 625 in two stages to artificially produce line and field drive signals, this is done to avoid tube damage in the case of no vertical drive ramp.
RGB drive signals are fed out on pins 17,18 and 19 of IC800. They are buffered to the tube base by transistors TR801, TR803 & TR803. External RGB signals and fast blanking come into IC800 on pins 21-24 as a nominal level of 700mV. Standard RGB video signals come from the Scart connector and are mixed with switching data from the main microcontroller IC500 for On Screen Display and/or the Teletext drive circuits. The fast blanking signal cuts off the analogue RGB and composite video signals in order to insert or key in the OSD or Teletext. It is sent by both the microcontroller and Teletext IC's.
The sensing of the beam current is performed at the bottom end of the EHT transformer, pin 7. 15V positive bias is fed via R350 and is reduced by the negative voltage generated by the G2 and Focus return current which is proportional to the TV tube beam current. Beam current sensing is done on IC800 pin 9, and is measured against an internal reference. When the sensing level exceeds this reference the gain of the RGB output stages is reduced, thereby reducing the beam current.

There are two signal inputs to this circuit from the tuner/ IF stages. TV video from the IF demodulator and the 6 0/6 5Mhz EM and NICAM intercarriers IC1 an ITT MSP3410 decodes standard FM sound and NICAM as well as carrying out the functions of Volume and tone controls and spatial sounds from the I2C bus A clock is generated on pins 62 and 63 at 18.432MHz. TV video is buffered by TR700 to IC4 via TR8 and SCART2 video to IC4 is via TR20, IC4 selects TV or SCART2 by using the SCART2 enable control signal from IC500 and the Scart menu. The resultant video output signal from IC4 is split, one part is fed back to the input of IC400, pin 11 as 'SAT VID O'. The other signal 'VID PERI O' is sent to pin 19 of SCART1 as an output. SCART1 video input is also routed to IC400, pin 12. In this way, SCART1 (VCR) can record the signals on SCART2 (Satellite). The audio switching is routed by IC1. SCART1 stereo audio input signals go to pins 52 & 53. SCART2 stereo audio input signals go to pins 49 & 50. SCART1 audio output signals come from pins 36 & 37. SCART2 audio output signals come from pins 33 & 34 TR12 to TR13 are SCART muting switches.
0.12 m
Control signals CTR out 1 and CTR out 2 control audio muting as in the case of tuning and TR9 mutes all audio outputs when the TV is switch off and residual voltages are still present in the power supply capacitors.
TV stereo or the selected SCART audio inputs come out of IC1 pins 28 & 29 to the stereo audio amplifier and internal speakers.
Note that either of two audio amplifier IC's TDA2007A or TDA2615 may be fitted.

Video output transistors TR900, TR901 & TR902 are drive directly from buffer transistors on the output drive signals of IC800 in the Y/C processing circuit. The level of the signal applied to the tube base is set in a register within IC800. There are also two registers for the signal parameters within IC800 for contrast (Y & C) and brightness (Black level) Emitter capacitors C900-C902 are present to provide extra gain at high frequencies to overcome loss by tube electrode capacitances

Transistors TR903, TR904 & TR905 are dark/light current sense transistors and combine to a single path for current sensing in auto grey scale mode.
Auto Grev Scale.
When a video output transistor is driven on by a peak white the voltage drop causes the sensing transistors to conduct producing a collector current proportional to the beam current. When the video output transistor is turned of by a black level then the current from the sensing transistors reduces to a lower level. This gives two current values on the Dark-I line representing residual dark tube current and maximum beam current.
