Va salut

 

Acest tv. a venit cu sunet slab de tot. Se aude doar pana la 30% volum. De la acest prag volumul nu se mai aude. Am crezut ca este de vina CI.ul final sunet(TPA110D2), pe care l.am inlocuit si tot la fel face. Tensiune alimentare CI 12V, la iesirea pe dif.uri creste doar pana la 6v, apoi descreste. I.mi scapa ceva, ma puteti ajuta cu o idee ?

TV. rezolvat. Din graba nu masurasem atent dif.urile.Au sunat la buzzer, dar nu am bagat de seama ca rez.ohmica a difuzoarelor era 0.00. Acum la o masuratoare mai atenta am observat acerst fenomen si implicit a aparut intrebarea : cum mama dracului sunt puse in scurt amandoua difuzoarele ? Din practica mea e cateva zeci de ani nu am intalnit difuzoare in scurt .Le.am inlocuit si acum functioneaza sunetul normal.
