electronix_2006 Posted June 14, 2014 Share Posted June 14, 2014 Salut,am un TV Universum FT7132 cu sasiu Finlux5000 care se manifesta cu urmatorul defect:sunetul este bun,OSB este bun dar imaginea nu are luminozitate,posibil lipsa semnal luminanta.Am inlocuit TDA4565,TDA2579A si se manifesta la fel.Daca modifici lumina,culoare,contrast aceste functii sunt active dar imaginea este tot fara luminozitate,se vad doar culorile.Daca aveti un sfat si ma puteti ajuta pentru rezolvarea acestui defect.
