You aren't logged in. (Guest)   1 graetz: 4R416 (4 R 416); Comedia,Reparaturtip  Hallo an alle Forumbesucher. Habe bei diesem Gerät einen interessanten Fehler beobachtet. Möchte mich mit einem kleinen Reparaturtip beteiligen. Fehlerbild: UKW Empfang leicht verzerrt,magischer Fächer reagiert sehr träge. Ursache: Defekter Widerstand,30 KOhm parallel zum Ratioelko, ist unterbrochen. Vielleicht hilft das dem einen oder anderen. Gruß, Florian Langer To thank the Author because you find the post helpful or well done.      Help
