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!

Spare Parts Lists ................................ 3-1…3-10

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.
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!

Chassis L5C-14"…20"GRUNDIG Service

Displayvarianten

Je nach Verfügbarkeit werden Dis­plays verschiedener Hersteller ein­gebaut. Dies führt zu unterschiedli­chen Chassis-Bestückungen, sowie
zu Änderungen in der Software. Bei
Ersatzteilbestellungen und Soft­ware-Updates achten Sie bitte auf
das eingebaute Display, sowie auf
den "Product Code". Angaben dazu
finden Sie auf der Geräterückseite.
Sollte in der Ersatzteilliste eine Dis­playvariante nicht aufgeführt sein,
wenden Sie sich bitte an die techni­sche Hotline.

Überprüfen Sie vor Austausch der
Hauptplatte, ob die Aufkleber der
Platinen identisch sind.

Display Variants

Depending on availability displays
of different manufacturer are built
in. This results in different chassis
mountings as well as a different
software. On spare parts orders as
well as software updates take care
of the fitted display as well as of the
"Product Code". Therefore you can
find information on the labels on the
rear side. If a display variant is not
mentioned in the spare parts list
please contact the technical hotline.

Before changing the main board
please check whether the labels on
the boards are identical.
