Sziasztok!
Került hozzám a felvezetőben említett készülék amelynél a kép erősen brummos. Elkókat átmérve kapacitásmérővel jónak tűnnek, szemre a sasszin látható hiba nincs. Itt leakadtam. Jól jönne egy segítő lökés, mert már lefáradtam.
Ügv.Ckó
My old TV has just broke a day ago, and when i try turning it on, relay is clicking and tv is not starting. I have heard that it probably has magnificying transformer broken.
Üdv!
Tönkrement a táp egy Grundig CUC 7303 tévében.
Eddig cserélve lett a R661 220Ω, D663 Z3,6, T665, C626 47μF/400V és az UC3842N IC is rossz lehet, de még nincs meg, ezért nem tudom még működésre bírni.
A T665 helyett csak 2SC3795 típusú tranzisztor volt itthon. Paramétereit tekintve nagyon hasonlít az MJF18004-hez.
Használhatom-e tartósan a 2SC3795-öt?
Köszi
