Am acest tv cu urmatorul defect,se aprinde,dar cand apas pe p+ se aprinde cifra 1 da sa porneasca si ma arunca inapoi in standbay,si se aude ceva dubios in zona trafului de linie ,am schimbat ceva condesatori+trafo linii dar tot persista problema, TEA2029C,TDA8390A,SAA5231,STV5342,BU508AF,, TDA8170,pe sasiu mai scrie MIVAR TV 3796, model spania,ce poate fi,un ajutor.

Incearca sa pui bec in locul finalului linii si vezi daca mai arunca sursa in standby > si masoara tensiunea pe bec !!
