Dumitrache_S Posted December 14, 2013 Share Posted December 14, 2013 Buna ziua . La un tv Hyundai model 14B9T61-TXS cu sasiu Beko 12.6 ( nu sunt sigur ) , ( procesor SDA 5535 A070 , jungla NN 5198K dispus oblic pe sasiu , memorie smd 24C04 ) nu pornesc liniile .Am schimbat conzi din sura si din primar si din secundar , am scos finalul linii si am pus un bec , pleaca din st-by si am tensiunile bune , in baza finalului am impulsurile de lini dar oscilograma este dreptunghiulara .Mentionez ca cu finalul lini montat ,cind ai dau start tensiunea din colector scade brusc .Daca aveti ceva ideii ar fi bine venite .Stima Quote Link to comment Share on other sites More sharing options...

BUGHIU Posted December 14, 2013 Share Posted December 14, 2013 Daca puteti masura direct pe colector final linii....nu e in regula!! Ori nu vine impuls corect(defecte de jungla,dreiver);ori vine impuls corect dar oscilatorul linii(BU+bobina primara trafo linii+condi intoarcere linii)blocat/defect!! Cauze: scurt/intreruperi pe tensiunile recuperate....Nu cred ca mai are rost sa intreb de condi din baza BU808DF si nici daca este bun BU808?!?!?

Dumitrache_S Posted December 14, 2013 Author Share Posted December 14, 2013 Am schimbat condul din baza (sata am facut prima oara ) si pe recuperate nu am nici un scurt.Stima Quote Link to comment Share on other sites More sharing options...
