Buna ziua.

 

Sunt la inceput de drum in depanare LCD, LED...Tv.ul nu afiseaza imagine, sunet exista.Am verificat toti condensatorii din sursa +invertori cu ESR,am verificat lampi cu Tester si sunt bune toate , am verificat inclusiv cu semnal ,pe rand fiecare lampa si am imagine.Aici m.am blocat.Varog o idee ce sa mai masor, sau poate este un defect tipic la acest sasiu (mentionez ca nu stiu sasiul) .

 

Placa sursei are urmatore le componente active:

CI-SEM 2005

CI-4506GEH

Mos.ul-7N65

inca un ci.de pe care nu reusesc sa identific marca.

2.MBR20100CT

TR.invertor-TM-0917

 

Atasez cateva poze cu placa sursei, si va rog daca se poate as avea nevoie de o schema sa incerc niste masuratori.
