validae Posted November 10, 2013 Share Posted November 10, 2013 Verifica tranzistorul final linii, sa nu fie strapuns si de asemenea schimba condensatorul electrolitic din baza lui, daca e uscat nu mai comanda bine tranzistorul.Mai verifica si lipiturile la trafo linii si nu numai, chiar cu lupa, poti avea lipituri reci care au cedat in timp.
