Sziasztok!
A fenti készülék azt produkálja, hogy ha CD-re kapcsoljuk, a lézeregységet a lemez közepe helyett kitolja a lemez szélére, és ott keres fókuszt, persze, hiába. A BA6898 már cserélve, a hiba uaz. Az IC 701 16-os lábán (SL out) ilyenkor a 2,5V helyett 4,5V van. Amíg a tálcát kinyitjuk, betoljuk, a rendes 2,5V mérhető, ahogy a tálca a helyén van, felugrik 4,5v-ra, ennélfogva a BA 2. lábán is 4,5V mérhető, az 1-en kb.1,5V, vagyis még tolná kifelé a lézeregységet, a SL motor állandóan forogna.
Megköszönném a segítséget.
Üdvözlettel
Attila
Sziasztok!
Hátha valakinek új!
Egy órás-rádió hangja halk, torz. A hangszórón a jel jó,a membrán mozog, és ohmikusan is jó. Szétszedve a következőt láttam: (Csatolmány) A mágnes teljes egészében elporlott, csak a lágyvas korong maradt meg. Ilyet még nem láttam! Lézeregységek mágneseinél láttam már hasonlót, de ott csak néhány szemcse vált le, és szorult be a tekercs és a mágnes közé. Eltávolítva tovább működött.
Üdv
Attila
Nagyon megkoszonném annak, aki tenne fel, egy LANEY LG 12 /kombo/ szervízkonyvet. Elore is koszonom...
