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 wie z.B.
Chassis, Netzschalterplatte, Bedieneinheit, Bildrohrplatte, Ablenk­einheit, Lautsprecher usw. 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.

General Section

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.

GRUNDIG Service Chassis 16.1

Sicherheits-Hinweise

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.

Service-Hinweise

Chassisausbau

Bevor Sie die Chassis-Verbindungsleitungen lösen, muss die Leitungs­verlegung zu den einzelnen Baugruppen wie Netzschalterplatte, Bedien­einheit, Bildrohrplatte, Ablenkeinheit oder Lautsprecher beachtet wer­den.
Nach erfolgter Reparatur ist es notwendig, die Leitungsführung wieder
in den werkseitigen Zustand zu versetzen, um eventuell spätere
Ausfälle oder Störungen zu vermeiden.

Safety Advices

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 +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.

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 ver­hindert Störungen aus dem Netz und ist Bestandteil der Geräte­zulassung. Im Ersatzfall bestellen Sie bitte ausschließlich das Netz­kabel laut Ersatzteilliste.

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.

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.

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

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.

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.

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.

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.
