tv color TITANIUM 21TIT TXTI defact sursa alimentare


Recommended Posts

Sa traiti,am un tv color Titanium 21TIT TXTI care in momentul conectarii la retea,face o oscilatie iar led-ul de control se aprinde si se stigne incontinuu.Sursa de alimentare are un circuit integrat TDA 4605. Am verificat tranzistorul final linii si este in regula,l-am verificat gandindu-ma ca pote fi in scurt si blocheaza tensiunea de iesire de pe sursa.Problema esca ca nu am o schema a acestui tv.

poate sa fie un consum suplimentar ( trafo linii sau iesiri recuperate din traf..sau alt consum.) decuplati colectorul acestui tranzistor ( final linii ) si montati intre colector si masa un bec de 60 W. vedeti dac se aprinde. schimbati si c-urile din primarul sursei preventiv.
