Üdv. Mester urak!
Előzmények: T4 biztosíték kiolvadva, DC/DC konverter IC10 KA5M0280R (FPS) ic tönkrement. Cseréltem, de KA5M0380R-re, mert csak azt kaptam. Működik, de nem stabil a Vscw feszültség, cca. 80-118V között lüktet. ( Az elkókat kicseréltem.)Azt szeretném kérdezni, hogy lehet-e valamilyen átalakítást végezni az áramkörön, hogy ezzel az ic-vel is rendesen működjön, vagy esetleg más hiba lehet? Van egy szerintem söntstabilizátor IC (IC9) az áramkörben, esetleg az a ludas? Hogyan lehetne azt beazonosítani? 3B és 560 felirat van rajta. A TL431-es sorozatban csak 2B feliratost találtam.
Cseréltem IC9-et TL431AC-ra, most már stabil. Ez volt a hunyó.
Sziasztok. Hozzám került egy LG 32LB650V típusú 3D LED TV ami bekapcsol, de nincs háttérvilágítás. A táp panelen a szervízdoksi alapján a feszültségek jók kivéve a LED kimenetet. 117V-nak kellene lennie de én 0V-ot mérek. Bekapcsoláskor a standby LED 7-et villan. A diódákat kimértem, a kondikon nem látok "púposodást". Lehet LED panel hiba?
