TV Grundig 40VLE 4322 BF

Recommended Posts

Am nevoie de schema la acest TV.  Din mers s-a oprit lumina de fundal , s-a mai aprins odata si gata acum nu am decat sunet iar imaginea s-ar mai vede niste umbre.

Din sursa ies mai multe fire catre display iar c-uriel care filtreaza tensiunea pentru leduri par bune dar sunt la 35v , nu am mai intalnit asa ceva . La altele erau de 100v. ce parere aveti?
