1.posibil ca alimentarea bv sa se faca din transformatorul de linii ,.2.daca ati scos bu808 ati anulat etajul cu transformatorul de linii . deci este normal sa nu aveti tensiune pe acel condensator .3. incercati sa urmariti cum se face pornirea /oprirea st-by4.daca montati bu808 apar tensiunile la trafo linii ?
