Guest ivovi Posted April 25, 2014 Share Posted April 25, 2014 (edited) Am un fax Philips la care s-a defectat susrsa de alimentare, am schimbat 3 condensatori care erau umflati dar tot nu vrea sa mearga in sensul ca tensiunile de la iesire fluctueaza mult (14V-16V sau 8V-10V) la fel si tensiunea Vcc de pe uc3842B 10V-14V (aici nu ar trebui sa am o tens stabilizata de 14V?) Unde ar putea fi problema? Mentionez ca sunt novice in ale elctronicii dar mi-ar place sa mai invat cate ceva in timpul liber Multumesc!

Guest ivovi Posted April 29, 2014 Share Posted April 29, 2014 Multumesc de raspuns, dupa ce inlocuiesc ci-ul o sa revin cu un mesaj. Quote Link to comment Share on other sites More sharing options...
Dr.L Posted April 29, 2014 Share Posted April 29, 2014 CI = circuit integrat C = condensator. Trebuie sa inlocuiesti condensatorul, nu integratul Quote Link to comment Share on other sites More sharing options...
