Buna ziua.Ma poate ajuta cineva cu o idee privind tv de mai sus.A avut defecta sursa,am rezolvat-o,am schimbat cele 2 condensatoare din sursa 10micro/63v,47micro/63v,am schimbat 2sa1013,am schimbat finalul de linii.Acum tv porneste insa cu dunga.Daca ating cu varful testerului de masura pinul 41 al tda 8362 imagina se desfasoara,pe pinii la deflexie am 12,3v iar tv functioneaza pana la o noua oprire.Atunci cand tv nu functioneaza pe pinii de intrare ai Tda 3653 am 0v,iar pe conectorul de deflexie am 2,3v.Am inlocuit toti condensatorii din baleiajul vertical.Tensiunea de alimentare a TDA 3653 este 25v indiferent de stare(cu dunga s-au fara).Ce sa ii mai fac?
