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 ustand 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 1:1 - 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! Austausch der Hauptplatte Nach Austausch der Hauptplatte müssen alle Einstellungen im Service Mode nach Tabelle "Grundeinstellwerte" (Punkt 1 im Kapitel "Serviceund Sonderfunktionen" auf Seite 1-7) eingestellt werden.

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 1:1 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! Change of the Main Board After changing the main board all settings in the service mode must be done according to the table "Basic Settings" (point 1 in chapter "Service and Special Functions" on page 1-7).

Geräte- und Display-Varianten
Display- und Product Code 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 des Service Manuals eine Display-Variante 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.

Product and Display Variants
Display and Product Code 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 of the service manual, please look for a vurrent 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.
