TV Platinium

Recommended Posts

TV Platinium model RML-21LM03TXT , am o problema cu acest TV , i-am gasit rezistenta din sursa carbonizata de la un soc de curent + 2 diode din puntea redresoare , le-am inlocuit si am inlocuit si circuitul 3S0680RF , si nu imi porneste sursa , tensiunile in primar sunt bune , dar in secundar nu am nici macar un volt pe toate liniile. Ar trebui sa schimb cumva si octocuplorul ? Daca puteti sa imi trimeti o schema si o sugestie va rog .

Mai mult ca sigur trebuie schimbat optocuplorul si nu numai acolo sigur sunt si printre rezistente macar una arsa,pentru schema dati mai multe detalii despre sasiu si anume:procesor,jungla,cadre,sunet,memorie etc.

Este cu stv2248 , baliaj vertical stv8131 si tranzistor final D2499 . 

Vedeti daca se potriveste schema data de domnul dan-a2 cu sasiul dstra.
