Buna ziua , Am un televizor Color tac model Lt30c am cumparat televizorul defect si l-am reparat .Televizorul a venit insa cu lumina setata la 200% si imi trosneste toata ziua transformatorii de pe neoane pe langa faptul ca se vede lapte...Am nevoie de o mana de ajutor sa intru in service meniul televizorului .Multumesc

tv lcd funai destul de vechi 2005-2006 merge cateva ore 2-3 ore dupa care disparea backlightul,24v de volti este ok,l-am suplimentat cu o alta sursa,acelasi rezultat,dupa ce merge 2-3 ore daca este repornit mai merge 15-20 minute si cade iar,personal banuiesc neoane obosite,albul nu e alb perfect,e cu o tenta de roz,(nu galben ceva obisnuit la unele paneluri)momentan sap in invertor sa refac ceva lipituri,nu de alta dar in rest pare ok invertorul,vreau sa anulez protectia,intrebarea e daca are ceva de suferit daca merge cu protectia eliminata,am gasit acesta varianta si vreau so testez,precizez ca nu sant probleme de sursa care este detasabila la 24v,placa digitala pare ok ,a-m gasit 8conzi de 10mf 16v obositi,vreo 6 pe partea de sunet si 2 pe langa memoria flash,i-am schimbat,mai mult ca sigur neoane obosite sau invertor,totusi ma gandesc sa nu fie si ceva contacte imperfecte pe invertor ce se manifesta cand ajunge la o anumitata temperatura dupa cca 2-3 ore,de merge bine ata timp,sau vre-o componente se ambaleaza termic,inveror darfon v144-001, oz960g, lm339,lm393,fds8958a.mai jos un link rusesc cu ceva metode de anulare protectie,va multumesc http://tel-spb.ru/inv_za.html
