1.2 How to service, English-German-French
How to service
BeoVision Avant 32 DVD is supposed to be serviced in the customers home!
In order to support the general service strategy, a Back-up suitcase is available which
contains the TV chassis and additional modules.
With this it is possible to easily carry out service in the customers home. Feature
modules are included.
If the TV chassis is replaced, leave the EEPROM in the set. The chip is located on a
separate very small module.
By doing so, the entire identity of the set is maintained.
After having replaced the faulty chassis, please read out error codes, write them
down and let them follow the chassis going for repair.
After that clear error codes.
A manual containing block diagrams, schematic diagrams, PCB drawings and list
of electrical parts can be ordered (part no. 3538975).
This manual makes it possible to replace electrical components.
Serviceanleitung
Das BeoVision Avant 32 DVD ist für den Service beim Kunden konzipiert!
Zur Unterstützung der allgemeinen Servicestrategie steht ein Servicekoffer zur

sich auf einem sehr kleinen separaten Modul.
Durch Beibehalten des EEPROM bleiben alle gespeicherten Gerätedaten erhalten.
Nach dem Austausch des defekten Chassis bitte die Fehlercodes auslesen, notieren
und dem zur Reparatur eingeschickten Chassis beilegen.
Anschließend die Fehlercodes löschen.
Es kann eine Anleitung mit Blockschaltbildern, Schaltplänen, PCB-Layouts und
einer Stückliste elektrischer Bauteile bestellt werden (Bestell-Nr. 3538975).
Diese Anleitung ermöglicht den Austausch elektrischer Bauteile.
Comment effectuer la maintenance
La maintenance du BeoVision Avant 32 DVD est supposée être effectuée chez le
client !
