Allgemeine Hinweise

Vor dem Öffnen des Gehäuses zuerst 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 Koppelkonden-

sator 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 like

the chassis, mains switch panel, keyboard control panel, picture tube

panel, deflection unit, loudspeaker and so on.

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 oscillo-

scope, 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-Hinweise

Safety Advices

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 Netzt-

eilspannung +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 ge-

setzt 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.

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-

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.

Service-Hinweise

Chassisausbau

Bevor Sie die Chassis-Verbindungsleitungen lösen, muss die Leitungs-

verlegung zu den einzelnen Baugruppen wie Netzschalterplatte, Bedien-

einheit, Bildrohrplatte, Ablenkeinheit oder Lautsprecher beachtet wer-

den.

Nach erfolgter Reparatur ist es notwendig, die Leitungsführung wieder

in den werkseitigen Zustand zu versetzen, um eventuell spätere

Ausfälle oder Störungen zu vermeiden.

Cable dereseau

Ces appareils ne peuvent être utilisés qu ' avec un cable de connecion

original de réseau avec bobine antiparasite intégré dans la fiche de

secteur. Ce câble de réseau empêche des perturbations de réseau et

est partie de l'autorisation d'appareil. Si nécessaire commandez

uniquement le cable de réseau selon la liste de pièces détachées.

Netzkabel

Diese Geräte dürfen nur mit dem Original-Netzanschlusskabel mit

integrierter Entstördrossel betrieben werden. Dieses Netzkabel ver-

hindert Störungen aus dem Netz und ist Bestandteil der Geräte-

zulassung. Im Ersatzfall bestellen Sie bitte ausschließlich das Netz-

kabel laut Ersatzteilliste.

Nota di servizio

Smontaggio del telaio

Prima di sfilare i cavi di collegamneto col telaio è necessario osservare

la disposizione originaria degli stessi verso le singole parti come la

piastra alimentazione, l'unità comandi, la piastra cinescopio, il giogo o

l'altoparlante.

Dopo la riparazione è necessario che gli ancoraggi e le guide

garantiscano la disposizione dei cavi analogamente a quella data in

fabrica e ciò per evitare disturbi o danni nel tempo.

Service Notes

Disassembly of the chassis

Before disconnecting the chassis connecting leads observe the way

they are routed to the individual assemblies like the mains switch

panel, keyboard control panel, picture tube panel, deflection unit or

loudspeaker.

On completion of the repairs the leads must be laid out as originally

fitted at the factory to avoid later failures or disturbances.

Cavo rete

Gli apperechi devono essere messi in funzioni solo con il cavo originale

il colle gamento di rete e la sua spina di rete deve essere munita di una

bombina d´induttanza. In causa di sostituzione ordinate solo il cavo di

alimentatore che corrésponde alla lista degli accessori.

Mains cable

The TV receiver must only be operated with an original mains connecting

cable with an interference suppressor choke integrated in the mains

plug.This mains cable prevents interference from the mains supply and

is part of the product approval. For replacement please order exclusively

the mains connecting cable specified in the spare parts list.

Nota de servicio

Desmontaje del chassis

Antes de desconectar las conecciones del Chassis hay que observar

la dirección de dichas conecciones a los distintos grupos de construcción

como la placa de conmutación de red, unidad de control, placa del

zócalo del tubo de imagen, unidad de deflección o altavoces.

Después de haber realizado la reparación y para evitar fallos o

pertubaciones posteriores es necesario reponer las conecciones tal

como fueron instaladas originalmente en fabrica.

Information pour la maintenance

Dèmontage de chassis

Avant de défaire les connecteurs du châssis princip, il y a lieu de

repérer auparavant les liaisons correspondant à chaque platine comme

par exemple le C.I. Inter secteur, le C.I. Commande, le C.I. Tube, le

bloc déviation ou les haut-parleurs.

A la fin de l'intervention, les connexions doivent être remises dans leur

position d'origine afin d'éviter par après d'éventuelles défaillances ou

perturbations.

Cable de red

El aparato solo se puede usar con el cable de red original con choque

antiparásito integrado en el enchufe de red. Este cable de red evita

perturbaciones de la red y es parte de la autorización del aparato. En

caso necesario puede pedir el cable de red según lista de piezas de

repuestos.
