Ma numesc Mihai(micrist) si am un televizor Daewoo DMQ 2166TXT placa CP330. In timp ce priveam o emisiune imaginea sa strans devenind o linie orizontala.L-am oprit i-am desfacut capacul ca sa pot masura ceva tensiuni in etajul de cadre TDA 3653B dar cand l-am repornit ecranul nu se mai lumina. Nu am schema. dar am masurat ceva tensiuni in etajul de cadre( nimic nu e ars integratul nu se incalzeste) tensiunile par normale. De asemeni tensiunile pe tranzistorii din etajul video RGB(pe gatul tubului) sunt mari semn ca probabil etajul nu primeste semnal.Pe anod este tensiune inalta iar tensiunile de pe traful de linii par a fi normale.

Va rog frumos ma puteti ajuta cu o schema si eventual cu un sfat.([email protected]) scuze sunt nou si nu prea stiu cu se procedeaza.

 

Multumesc anticipat,

Mihai
