Buna, am o problema la un 11AK30 cand e folosit pe retea de cablu apare o dunga orizontala care se misca peste imagine si un barait puternic peste sunet. Daca il conectez la un receptor de satelit cu iesire antena TV merge OK.Pare ca un bruiaj de retea, care ar putea fi problema ?

Am cuplat la un receptor satelit cu iesire RF antena si merge perfect, presupun si eu ca tensiunea de retea intra un pic si in secundar.Am schimbat condensatorul de 4,7nf dintre secundar si primar si maine o sa-l testez sa vad daca rezolva problema.Altceva ce mai poate fi ? decat izolatia trafului din sursa presupun.Daca nu merge probabil o sa fac un izolator galvanic cu 2 conzi pe antena.
