Sony sasiu FE2


Recommended Posts

Am in atelier un astfel de aparat la care a fost transformatorul linii si tranzistorul final linii defecte.Fara aceste componente si cu sarcina bec+rez. sursa bilbiie rar(becul se aprinde si se stinge regulat cam la o secunda).Daca deconectez pinul31(VP3)de la TDA 9394H/N1/5/0583 sursa lucreza corect.Am pus traf linii si tranzistor final linii noi si cu pinul 31 conectat tv-ul porneste cu inalta dupa care se opreste alternind asa la infinit la acelasi interval ca si cu bec+rezistenta.Daca elimin pinul 31 sursa nu se mai opreste,apare rastru cu perna pe EW,fond albastru si cursa inversa iar ledul da eroare 5-IKR.Rugamintea mea este daca ma poate ajuta cineva cu schema interna a acestui circuit integrat pt. a ma asigura daca defectul este in el sau in alta parte.Multumesc!
