Va salut. Acest tv cu sasiu CP330 nu i se aprinde ledul si implicit nu intra in functiune .In timp ce fac masuratori in sursa, tv-ul intra in functie cu tensiunile normale.Daca il repornesc cat este ''cald,,functioneza perfect, iar daca il las cateva zeci de minute intrerupt de la retea povestea se repeta deci iar nu se aprinde ledul si nu porneste.Am schimbat toti electroliticii din sursa si nimic.Sursa este echipata cu A4601DC si D1555Va multumesc.

Masurati cu mavo ,in momentul cuplarii la retea (atentie,se masoara fata de masa primara) tensiunea la pinul 9 al 4601.Trebuie sa salte peste 12v,altfel nu porneste.Daca nu salta peste 12v,suspect este circuitul de alimentare din retea- r807,808,809 si filtrajul de la pin 9-c817(sigur nu a scapat neschimbat?) precum si integratul -poate consuma curent prea mare.
