Buna ziua, am un un LCD MINI TV "NEWTRON" care din gresala a fost alimentat la 24v, in loc de 12v, din ceia ce am reusit sa identific: sa ars o siguranta fuzibila F2, a puscat un condensator de 470uF/16v si unul din tranzistori din invertorul ccfl. Luminand ecranul cu o lanterna cu led, se vede imaginea. Am schimbat piesele defecte, tranzistorul original este pe capsula SOT-89 si inscriptionat SM/DKL, pe care le-am schimbat (ambele) cu 2sc5770, la alimentare unul din tranzistori se incalzeste puternic si nu porneste invertorul. Posibil sa nu fie tranzistori cei echivalenti cu cei originali ?? Cum as putea rezolva problema cu invertorul ?? Va multumesc!
