defect sursa tv Arctic sasiu E1


Recommended Posts

Salut pe toti meseriasii in domeniul electronicii.Am un televizor ARCTIC cu sasiul Z50.190-05,avand sursa TDA16846 si tranzistor K3567.A functionat bine o vreme dupa care s-a oprit.La pornirea din butonul frontal care alimenteaza tv-ul cu curent, led-ul albastru palpaie permanent, timp de 10-15 secunde dupa care se stinge.S-a inlocuit integratul TDA16846 si tranzistorul K3567 si tot nu porneste.S-a decuplat alimentare linii si s-a pus un bec de 60wati si in momentul cuplarii tv la priza de curent ,becul se aprinde cateva secunde,dupa care se stinge.Rog toti cunoscatorii in domeniu sa ma lamureasca si pe mine cam ce defect ar putea avea tv-ul meu.Cu stima si respect. :jytuiyu
