Elite 21ES57 lipsa sonor


Recommended Posts

Se pare ca este un tv fabricat in Bulgaria.Sursa este pe tranzistori.Procesor tda9361ps/n2/5l  ,cadre LA78040.Sunet  AN7522N.Sonorul este foarte slab ,se aude numai cu urechea aproape de difuzor.Am inlocuit de probe ci sunet cu  AN17821A si nici o schimbare.Din cate stiu eu la chinezisme daca eliminai unu...doi tranzistori revenea sonorul.Am nevoie de o schema ,eventual un sfat cum sa procedez.

Pentru ca l-am primit fara telecomanda ,de retinut un cod MFY pt acest tv este 1491.Sonorul se pare ca are ceva pe partea de volume control ,inca nu am depistat ce.  Cum se intra in service la acest sasiu?
