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-Techni­sche Bundesanstalt (federal physiotechnical institution). The high tension for the picture tube and thus the developing X-ra­diation 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 demodula-
tor.
• 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 de-
modulator 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

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.

LA7840 Vertical Deflection Output Circuit
Features
• Low power dissipation due to built-in pump-up circuit
• Vertical output circuit
• Thermal protection circuit built in
• Excellent crossover characteristics
• DC coupling possible General Description The LA7840 is a vertical deflection output IC for TVs and CRT dis­plays with excellent image quality that use a BUS control system si­gnal processing IC. This IC can drive the direct (even including a DC component) deflection yoke with the sawtooth wave output from the BUS control system signal processing IC. Because the maxi­mum deflection current is 1.8 Ap-p, the LA7840 is suited for small and medium screen sets.
TDA6108 Triple Video Output Amplifiers
By integrating three video amplifiers in a single IC, the TDA6108 ICs provides a single IC solution for driving color TV CRTs. Each device in the TDA6108 family contains three video output amplifiers in one plastic DIL-bent-SIL 9-pin medium power (DBS9MPF) packa­ge (SOT111-1). Using high-voltage DMOS technology, this enables each of these ICs to drive the three cathodes of a color CRT di­rectly, providing a significant reduction in the Bill of Materials for new designs. For maximum performance, the TDA610x amplifiers should be used with black-current control, enabling automatic black current stabilization and removing the need for any external align­ments on the CRT board.

TDA8601 RGB/YUV and Fast Blanking Switch
Features
• YUV/RGB and fast blanking switch
• 3-state output
• Selectable clamp: – passive (with diodes) or active clamp
• Bandwidth greater than 22MHz
• Fully ESD protected
• Latch-up free.
General Description The device is intended for switching between two RGB or YUV vi­deo sources. The outputs can be set to a high-impedance state to enable parallel connection of several devices. A HIGH level on SEL (pin 5) selects the video inputs of Channel 2. The IOCNTR control pin (pin 16) defines the 3-state outputs and clamp inputs:
• HIGH = 3-state outputs (also for test; active clamp)
• LOW = passive clamp at the video inputs (diode)
• Sandcastle: the video signal is clamped with an active clamp du­ring the sync pulse.
