tv Lg ce29q10et

Recommended Posts

Am un tv Lg ce29q10et,cand incerc sa-i dau drumul (pornesc) nu mai vrea.

Precizez ca ledul rosu sta aprins dar cand apas pe buton sa-l pornesc se aude doar un zgomot (ca si cum ar vrea sa porneasca ) dupa care nimic nu se intampla,ledul rosu tot aprins ramane.

Ce ar putea sa aiba?

Cateva poze cu TV-ul:

Am revenit cu poza full de la sursa:Posted Image

Am dezlipit traful de inalta tensiune.

Pot sa testez (verific tensiunile) sursei fara restul televizorului?,trebuie sa dezlipesc si tranzistorul de putere?

Daca ati scos trafo linii....nu mai are rost sa scoateti si tranzistorul!!!Mai usor era sa scoateti tranzistorul decat trafo....sau bobina prin care se alimenteaza etajul linii!!!Va trebuie cuplata la sursa si partea de procesor,altfel nu are cine sa dea ON/OFF sursei(optocuplorului)
