am in lucru acest model de schneider sasiu TV9 cu tda8177f in cadre,si nu sant lamurit ce tensiune de alimentare are pe cadre.in schema zice 45v,iar in televizor am 64v.tubul e cu diagonala de 66cm.e posibil sa aiba alimentare la valoarea asta?tensiunea data de sursa e 145v,traful de linii lam schimbat pt ca scotea tensiuni mari.acum functioneaza fara descarcari dar nu sant lamurit cu cadrele.

Salut!pe care pin ai masurat 64v?ca circuitul se alimenteaza pe pinul 2.pe schema parca-i trecut 3.in datasheet ai specificat tensiune de alim.pe pin2=40v fata de masa.

pe pinul 3 are 64v fata de masa.
pinul 3 zice ca-i flayback generator :rolleyes:

nu ai citit atent,acolo e flyback supply,cu alimentare maxim 70v.deci teoretic ar trebui sa reziste.
