coman ion Posted December 29, 2013 Author Share Posted December 29, 2013 Multumesc pentru scheme!Fa totusi o verificare simpla:baga un semnal de la un dvd sau de la iesirea de casti a telefonului direct pe intrarile finalilor (punand evident un cond de separare) si vezi daca iese ceva.Poti merge cu acest semnal si mai inapoi,pe intrarile driverelor u7,8,9.
