Hello, there was also discussion about the scheme of this source where elektrotanya site only gives parts, components and front-to-back pictures. I would be interested in at least the values of the smd components next to the integrated ICM802S = 2S110 (SSC2S110) and the arrangement of the resistor RM81O (which I think that it was 560R). Maybe someone found it. Thanks very much !
Üdv!
Kűzdök egy 51-es Samu KS9A-val. Nincs G2 fesz. Szűrőkondi, foglalat cserélve. Ha kihúzom a foglalatból a kábelt és utána visszadugom, megjön a fesz és a kép és meg is marad bármeddig. Miután így járatom, ki-be kapcsolhatom, rendesen működik. Próbaképp adtam neki a trafó helyett feszt a 180V-ról, nem terhelt be. Szerintetek trafó vagy cső?

A probléma megoldva! Boosterből pótoltam a segédrács-feszt, persze, leosztva.
Mindenkinek köszi!
Kellemes Karácsonyt!
Sziasztok!
A fent nevezett tv került hozzám 4:3-as slim képcsővel, (előélete ismeretlen), szétszedve a sortranzisztor FJL6920 hiányzott belőle. Ezt kipótolva a sortrafóból nagyon halk, kb másodpercenként 2 ciccenés hallható. A tápok nincsenek meg, ill. a B+ táp alacsony értéken pulzál. A sortranzisztort kiemelve, helyére 75W-os égőt betéve, a B+ tápfesz 135V (ez jó), a tv újraindulgat, hallható a hang logójából.
Mi lehet a baj, ebben kérném segítségeteket. Talán hibás a sortrafó, és ez terheli be nagyon a tápot? a sortranzisztort nem öli meg, a sortrafó nem meleg sehol sem.
Köszönettel: Zsoca
