Buna ziua!Acest tv are sasiu TH TDA11105B PCB.Am gasit D1555 (final linii)in scurt ,nu am avut la fel am pus 2SD2527DF.

Inainte am facut testul cu becul ,tensiunile sunt OK, am verificat conzii.Par a fi in regula.Dar tv face urmatorul fenomen,vrea sa porneasca ,apar impulsurile pe baza la BU,dar face un sunet trrrrrr de 3 ori  cu pauza,si nu porneste inalta.Eu banuiesc trafo linii ,in orice caz am masurat si tensiunea pentru microprocesor si nu are 5V are mai putin,dar am dat de la o sursa externa si acel sunet trrrrr a disparut ,dar inalta tot nu vine ,

si am masurat ca tensiunea de 180V este doar 60V.Acel sunet trrr se aude din  in trafo linii.

Ce parere aveti?Va multumesc!

Eventual o schema mai buna daca are cineva ca al meu abia se vede.
