leo 17 Posted March 17, 2015 Share Posted March 17, 2015 la modelul de tv mentionat sursa e cu str w 6753.am gasit arse doua rezistente langa integrat una 2,7 ohm de 3w si una de 220 ohm si o bobina care duce la choper din integrat ..circuitul cred ca e defect asa ca am pus un ups sa verific daca functioneaza asa ..pe condesatorul de filtraj am o tensiune care fluctuiaza ..deci am schimbat si condesatorul de filtraj .diodele de redresare sunt ok verificate ..ce sa mai verific ?

dan cod Posted March 18, 2015 Share Posted March 18, 2015 Normal trebuie sa ramana in primar doar redresarea de 300V iar in secundar doar dioda redresoare pe U1 restulo dat jos.Probeaza pe bec sursa nu pe TV ca poate mai ai ceva defect acolo.

leo 17 Posted March 18, 2015 Author Share Posted March 18, 2015 am scos tot din primar si am eliminat toate diodele de redresare doar cea pt bara de alimentare 123 de v am lasat o ..am schimbat si diodele pt redresare primar si filtraj ..am schimbat si ups (ma gandeam poate e defecta)..tot asa imi face imi fluctuiaza tensiunea pe iesire .a mai ramas chopper ..

dan cod Posted March 18, 2015 Share Posted March 18, 2015 Daca ai facut toate astea corect poate fi chopperul defect dar inainte schimba si dioda pe U1 pune UF5408 Quote Link to comment Share on other sites More sharing options...
