Witam
Proszę o pomoc dotyczącą zasilacza ORTP-760(SM-2)-Q20 w w/w Samsungu.

Po włączeniu na złączu CN01 pojawia się 55V i od razyu spada do 0V. Poza tym na ty złączu jest nieznacznie zaniżone 12 i -12.
Wymienione diody i ZD01, ZD03 (wstawiłem diody Zenera na 4,7V i 9,1V), D07 (UF4007) i KA5Q1265RF.

DVD uruchamia się lecz brakuje dźwięku. Po podaniu 30V na CN01 DVD pracuje poprawnie.
