Salut. Sunt nou pe aici. Am un tv Royal care se manifesta astfel: cand il pornesc se aude un "fasait" in zona trafo inalte, nu se vede nimik pe ecran, si nici sunet. Am schimbat un C618 de pe linia de 115V care era cam umflat, dar nimic, tot asa se manifesta. Este posibil sa fie defect trafo inalte? O seara placuta. Schema http://forum.microprocesoare.ro/index.php?topic=156.0

Tv contine urmatoarele: TDA8305A, PCA84C640P/030, tda4650, tda183410
