nelutuPO Posted January 9, 2015 Share Posted January 9, 2015 Buna seara, am un tv cu sasiu 11AK56-4 la care pleaca liniile 10 sec dupa care pilpie led-ul de 3 ori si trece in standbysi nu mai pleaca decit repornit de la retea. Am ridicat UG2 si are dunga orizontala cit are inalta. Inlocuit CI BV , dioda BA159 , 100Mf/50 V , Q602 , tensiunile -/+ 14 V corecte. Va rog un sfat. Stima Link to comment
ruscanusorin Posted January 9, 2015 Share Posted January 9, 2015 Cat timp pornesc liniile , recuperata de 8 volti exista? Link to comment
dan cod Posted January 9, 2015 Share Posted January 9, 2015 Eu as pune osciloscopul pe BV in 10 secunde este ce vedea. Link to comment
Florinel TV Posted January 9, 2015 Share Posted January 9, 2015 posibil defect ic bv si cel montat tot defect Link to comment
nelutuPO Posted January 9, 2015 Author Share Posted January 9, 2015 Osciloscopul il am defect ireparabil ( cazut jos si kaput ) iar in privinta CI BV am pus 3 diferite si la fel. Da tensiunea de 8 V este ( am avut odata cu Q602 BC639 defect si nu aveam tensiunea de 8 V ) Link to comment
dan cod Posted January 10, 2015 Share Posted January 10, 2015 Nasol fara osciloscop.Poate sa lipsească si impulsurile de V. Link to comment
