Am gasit BU808DF defect. L-am inlocuit, si condensatorul de 10 mF, le-am pus noi, a functionat 2-3 zile bine (fara sa se incalzeasca). Acum tranzistorul este okay, dar nu mai porneste frecventa liniilor. Daca scot tranzistorul, am 15625Hz iar in CI STV2248 pin 48 am 2,8V si 15625Hz. Daca cuplez un tranzistor nou, tensiunea creste la 7,8V in pinul 48 si nu mai exista frecventa (deloc). Am intarit lipiturile in jurul transformatorului de linii si pe langa el. Nu am vazut nicio lipitura rece. Ajutati-ma.
