Salut, acest sasiu a venit cu nenumarate lipituri reci in jurul sursei si baleaj ho lucru care ducea la o pornire foarte greoaie. Am schimbat condensatorii din partea primara si secundara a sursei, decupland finalul linii si montand o sarcina artificiala (bec), tensiunea pe b1=115v. La comanda on, cu sarcina artificiala montata led-ul trece in culoarea verde. In momentul in care montez finalul linii, care este verificat, led-ul, in culoarea rosu, palpaie o singura data, fara ca tv-ul sa functioneze. Am decuplat tensiunile recuperatoare, pe rand, (tensiunea de cadre si tensiunea video) si simptomul este acelasi. Ce credeti ca s-a intamplat? Rog ajutor de la colegi care au intalnit acest defect. Multumesc anticipat!
