Allgemeiner Teil
Allgemeine Hinweise
Vor dem Öffnen des Gehäuses den Netzstecker ziehen! Achtung: ESD-Vorschriften beachten 
Leitungsverlegung
Bevor Sie die Leitungen und insbesondere die Masseleitungen lösen, muss die Leitungsverlegung zu den einzelnen Baugruppen beachtet werden.
Nach erfolgter Reparatur ist es notwendig, die Leitungsführung wieder in den werkseitigen Zustand zu versetzen um evtl. spätere Ausfälle oder Störungen zu vermeiden.
Durchführen von Messungen
Bei Messungen mit dem Oszilloskop an Halbleitern sollten Sie nur
Tastköpfe mit 10:1 - Teiler verwenden. Außerdem ist zu beachten, dass nach vorheriger Messung mit AC-Kopplung der Koppelkondensator des Oszilloskops aufgeladen sein kann. Durch die Entladung
über das Messobjekt können Bauteile beschädigt werden.
Messwerte und Oszillogramme
Bei den in den Schaltplänen und Oszillogrammen angegebenen Messwerten handelt es sich um Näherungswerte!

General Notes
Before opening the cabinet disconnect the mains plug! Attention: Observe the ESD safety regulations 
Wiring
Before disconnecting any leads and especially the earth connecting leads observe the way they are routed to the individual assemblies. On completion of the repairs the leads must be laid out as originally fitted at the factory to avoid later failures or disturbances.
Carrying out Measurements
When making measurements on semi-conductors with an oscilloscope, ensure that the test probe is set to 10:1 dividing factor. If the previous measurement was made on AC input, please note that the coupling capacitor in the oscilloscope will be charged. Discharge via the item being checked can damage the components.
Measured Values and Oscillograms
The measured values given in the circuit diagrams and oscillograms are approximates!

Sicherheits-Hinweis
Die in den Fernsehgeräten auftretende Röntgenstrahlung entspricht den Bestimmungen der Physikalisch-Technischen Bundesanstalt vom 8. Januar 1987.
Die Hochspannung für die Bildröhre und die damit auftretende
Röntgenstrahlung ist abhängig von der exakten Einstellung der
Netzteilspannung +B.
Nach jeder Reparatur im Netzteil oder in der Horizontalablenkung ist die Hochspannung zu messen und gegebenenfalls einzustellen.
Schutzschaltungen im Gerät dürfen nur kurzzeitig außer Betrieb gesetzt werden, um Folgeschäden am Chassis oder an der Bildröhre zu vermeiden.
Beim Austausch der Bildröhre dürfen nur die in den Ersatzteillisten vorgeschriebenen Typen verwendet werden.
Safety Advice
The X-radiation developing in the sets conforms to the X-radiation
Regulations (January 8, 1987), issued by the Physikalisch-Techni- sche Bundesanstalt (federal physiotechnical institution).
The high tension for the picture tube and thus the developing X-ra- diation depends on the precise adjustment of the +B 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.

IC Data Sheets & Specifications
IC 101 - OM 8365
The OM8365H combine the functions of a video processor together with a µ-Controller, US Closed Caption decoder and Teletext decoder. The Teletext decoder has an internal RAM memory for 10 page text. The ICs are intended to be used in economy television receivers with 110° picture tubes. The ICs have supply voltages of 8V and 3.3V and they are mounted in a QFP 80 envelope.
TV-Signal Processor
•Multi-standard vision IF circuit with alignment-free PLL demodulator.
•Internal (switchable) time-constant for the IF-AGC circuit.
•The QSS and mono FM functionality are both available so that an
FM/AM TV receiver can be built without the use of additional ICs
•The mono intercarrier sound circuit has a selective FM-PLL demodulator which can be switched to the different FM sound frequencies (4.5/5.5/6.0/6.5MHz). The quality of this system is such that the external band-pass filters can be omitted.
•The FM-PLL demodulator can be set to centre frequencies of 4.74/5.74MHz so that a second sound channel can be demodulated. In such an application it is necessary that an external bandpass filter is inserted.

•Switchable DC transfer ratio for the luminance signal.
•Only one reference (12MHz) crystal required for the µ-Controller,
Teletextand the colour decoder.

•Internal base-band delay line.
•Indication of the Signal-to-Noise ratio of the incoming CVBS signal.
•A linear RGB/YUV/YPBPR input with fast blanking for external
RGB/YUV sources. The synchronisation circuitcan be connected to the incoming Y signal. The Text/OSD signals are internally supplied from the µ-Controller / Teletext decoder.
•RGB control circuit with ‘Continuous Cathode Calibration’, white point and black level off-set adjustment so that the colour temperature of the dark and the light parts of the screen can be chosen independently.
•Contrast reduction possibility during mixed-mode of OSD and
Text signals.
•Adjustable ‘wide blanking’ of the RGB outputs.
•Horizontal synchronization with two control loops and alignmentfree horizontal oscillator.
•Vertical count-down circuit.
•Vertical driver optimized for DC-coupled vertical output stages.
•Horizontal and vertical geometry processing.
•Horizontal and vertical zoom function for 16:9 applications.
•Horizontal parallelogram and bow correction for large screen picture tubes.
•Low-power start-up of the horizontal drive circuit.
µ-Controller
•80C51 µ-controller core standard instruction set and timing.
•1 µs machine cycle.
•64 - 96Kx8-bit late programmed ROM.
•12Kx8-bit DataRAM (shared between Display, Acquisition and
Auxiliary RAM).
•Interrupt controller for individual enable/disable with two level priority.
•Two 16-bit Timer/Counter registers.
•One 16-bit Timer with 8-bit Pre-scaler.
•WatchDog timer.
•Auxiliary RAM page pointer.
•16-bit Data pointer.
•Stand-by, Idle and Power Down modes.
•14 bits PWM for Voltage Synthesis Tuning.
•8-bit A/D converter with 4 multiplexed inputs.
•5 PWM (6-bits) outputs for control of TV analogue signals.
•18 general I/O ports.
Data Capture
•Text memory for 10 pages.
•Inventory of transmitted Teletext pages stored in the Transmitted Page Table (TPT) and Subtitle Page Table (SPT).
•Data Capture for US Closed Caption.
•Data Capture for 525/625 line WST, VPS (PDC system A) and Wide Screen Signalling (WSS) bit decoding.
•Automatic selection between 525 WST/625 WST.
•Automatic selection between 625 WST/VPS on line 16 of VBI.
•Real-time capture and decoding for WST Teletext in Hardware, to enable optimized µ-processor throughput.
•Automatic detection of FASTEXT transmission.
•Real-time packet 26 engine in Hardware for processing accented, G2 and G3 characters.
•Signal quality detector for video and WST/VPS data types.
•Comprehensive teletext language coverage.
•Full Field and Vertical Blanking Interval (VBI) data capture of WST data Display.
•Teletext and Enhanced OSD modes.
•Features of level 1.5 WST and US Close Caption.
•Serial and Parallel Display Attributes.

MSP 34x0G Multistandard Sound Processor Family
The MSP 3410G family of single-chip Multistandard Sound Processors covers the sound processing of all analog TV-Standards worldwide, as well as the NICAM digital sound standards. The full TV sound processing, starting with analog sound IF signal-in, down to processed analog AF-out, is performed on a single chip. This new generation of TV sound processing ICs now includes versions for processing the multichannel television sound (MTS) signal conforming to the standard recommended by the Broadcast Television Systems Committee (BTSC). The DBX noise reduction, or alternatively, Micronas Noise Reduction (MNR) is performed.
Other processed standards are the Japanese FM-FM multiplex standard (EIA-J) and the FM Stereo Radio standard.
The MSP 3410G has optimum stereo performance without any adjustments.
The MSP 3410G has built-in automatic functions:
The IC is able to detect the actual sound standard automatically (Automatic Standard Detection). Furthermore, pilot levels and identification signals can be evaluated internally with subsequent switching between mono/ stereo/bilingual; no I2C interaction is necessary (Automatic Sound Selection).
The MSP 3410G can handle very high FM deviations even in conjunction with NICAM processing.
