BeoSound 1 Type 2581, 2582, 2583, 2584, 2585, 2586, 2587, 2590 Service Center repair guide English, German, French, Italian, Spanish How to service, English 1.1 How to service The product has been developed for simple module exchange to follow the Onsite service strategy. Module exchange is possible On-site, at the dealer or in the service workshop whatever is most convenient in each case. For On-site service a Back-up suitcase must be used. Module exchange This way of servicing is recommended, due to the fact that most of the modules are multilayer based, and most of the circuits are on a single main PCB. For On-site service it is possible to order a Back-up suitcase. Microcomputer If the main PCB is replaced, the entire identity of the set is maintained (security code included). If the main PCB is suffering from an intermittent fault, the display can read out error codes in test mode. CD mechanism exchange The CD-PRO II mechanism can be changed on-site or in service centres. Both the CD-mechanism and the servo/decoder PCB are one single unit for easy replacement and future update. There is easy access for cleaning the lens, and by means of test modes most fault symptoms are identified. Turntable gearbox The gearbox which loads the CD is a block module and must be changed as a complete part. FM antenna The antenna module can be replaced on-site. Speakers All speakers can be replaced (placed behind the removable front cover). There is simple sound level adjustment via the display. Amplifier Part of the main PCB. The only adjustment necessary after module exchange is the speaker sound level. Read out the values for adjustment (in test mode) before replacing the module - if possible. Display & IR The complete display and IR receiver module can be changed by removing the front cover only. Note! If it's necessary to exchange PCB1 (Radio/CD/LF/µP) and PCB3 (Display) at the same time (as a damage due to lightning) both modules must be send to Bang & Olufsen service department to be renamed. 1.2 Durchfьhrung von Reparaturen, Deutsch Durchfьhrung von Reparaturen Das Gerдt wurde fьr einfachen Modulaustausch im Rahmen des Vor-Ort-Service entwickelt. Der Modulaustausch kann vor Ort, beim Hдndler oder in der Service-Werkstatt vorgenommen werden, je nachdem, welcher Ort im Einzelfall geeigneter ist. Fьr den Vor-Ort-Service wird ein Reparaturkoffer benцtigt. Modulaustausch Dieses Serviceverfahren wird empfohlen, da die meisten Module mehrschichtig aufgebaut sind und sich die meisten Schaltkreise auf einer einzigen Haupt-PCB befinden. Fьr den Vor-Ort-Service kann ein Reparaturkoffer bestellt werden. Mikrocomputer Beim Austausch der Haupt-PCB bleibt die vollstдndige Identitдt des Gerдts (einschlieЯlich Sicherheits-Code) erhalten. Wenn die Haupt-PCB einen unregelmдЯig auftretenden Fehler aufweist, kann das Display im Testmodus Fehlercodes anzeigen. Austausch des CD-Mechanismus Der CD-PRO II-Mechanismus kann vor Ort oder in einem Servicecenter ausgetauscht w
