Allgemeiner Teil
Einführung
In dieser Service-Manual-Ergänzung sind die Chassisplattenvariante
X1P.190R-3, sowie eine Gerätevariante, die mit dem Chassis LH
ausgestattet ist, dokumentiert.
Hinweis:
Grundlage für den Service sind folgende Service Manuals:
– Service Manual Sicherheit, Materialnummer 720108000001
– Service Manual Chassis LH, Materialnummer 720100526000
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 Section
Introduction
This Supplement of Service Manual describes chassis variant
X1P.190R-3 as well as a set fitted with this chassis LH.
Note:
Basic instructions for servicing are given in following Service Manuals:
– Service Manual Safety, Part Number 720108000001
– Service Manual Chassis LH, Part Number 720100526000
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 LHGRUNDIG 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 Ihr "Product Code" oder Ihre Displayvariante nicht aufgeführt sein, können Sie
eine aktualisierte Version auf dem
GRUNDIG Service-Portal "http://
service.grundig.de" finden.
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 your "Product Code" or
display variant is not mentioned in
the spare parts list please have
look for a current version at the
GRUNDIG Service-Portal "http://
service.grundig.de".
Before changing the main board
please check whether the labels on
the boards are identical.
