balasmihail Posted August 6, 2019 Share Posted August 6, 2019 A venit un prieten cu acest televizor defect. La verificari am gasit traful driver si tranzistorul aferent defecte. Cu tranzistorul am rezolvat, dar traful imi creaza probleme fiindca infasurarea primara este partial carbonizata si nu pot afla numarul de spire. Are cineva din ,,greseala" acest traf sau poate sa-mi spuna ce numar de spire ar trebui sa fie in primar ? Quote Link to comment Share on other sites More sharing options...

balasmihail Posted August 6, 2019 Author Share Posted August 6, 2019 Problema este ca nici spatiul nu-mi permite sa montez altul de dimensiuni mai mari. Nu stie nimeni rezistenta ohmica a primarului, ca atunci m-as putea descurca. Quote Link to comment Share on other sites More sharing options...

balasmihail Posted August 10, 2019 Author Share Posted August 10, 2019 Inca odata multumiri pentru nostalgic, televizorul functioneaza perfect. Singura observatie este la numarul de spire din secundar, unde sarma era intacta, acesta fiind de 46 si l-am pastrat tot la fel. Quote Link to comment Share on other sites More sharing options...
