Guest inginer001 Posted July 6, 2009 Share Posted July 6, 2009 Salut.Am un monitor CRT, LG.Modelul este 7UF, F1770.Problema se manifesta in felul urmator.Cand pornesc monitorul, se aude un clickuit ca de releu, timp de 1-2 secunde si apoi nimic.Ecranul nu se aprinde.Problema a aparut in timp ce functiona. Dintr-o data s-a intrerupt.Daca ma puteti ajuta cu vreun sfat in privinta depanarii.Multumesc. Quote Link to comment Share on other sites More sharing options...

bogdanb1 Posted July 6, 2009 Share Posted July 6, 2009 incercati sa ascultati sunetul scos de sursade aici incepe reparatiatiuit, pocnet ceva... apoi urmatoarea oprire va fi finalul de cadre. de aici , cu el scos se va verifica daca sursa debiteaza si cit .si trafo linii trebuie privit cu atentie- conturnari pt cele externe cele interne se vad in functie de ce "zice" finalul de cadre sau alte masuratori specifice. colegii forumisti va vor safatui cum veti verifica sursa, cu ajutorul unui bec 220V 60 w sau un pic mai mic, asta pt punerea in sarcina simulata. sa va uitati si ce scrie pe finalul de cadre. atentie tranzistorul, sau ce veti gasi, este superior celor din teveuri. frecventa. cind veti cumpara piese atentie magazinele sint pline de tot feluri de tranzistori facuti in pivnite si inscriptionati ca la gradinita - trebuie luat ceva cu sigla unei firme pe el.sfaturile mele sint orientative. completati le cu experienta dvs si cu alte sfaturi.exemplu final cadre monitoare bu1215. echivalenta bu1015.
