pe bobina releului sunt 5v cind e in stanb by....in momentul cind dau sa il pornesc tensiunile toate dispar.....si ledul se stinge complet....efectiv tv moare total

 

Pai si nui putin 2,56v in loc de 3,3 , hai 3,18v dar nu sub , atunci procesorul nu se alimenteaza corect si de aici toata problema cu pornirea

am schimbat releul ca facea figuri,ceva conzi si acum in pinul 16 am 3,2v. iar u1 este 83v,la fel 3v3 stanby e prezenta ....dar in pinul 4 tot 0v.....si partea ciudata e ca daca i dau plecare din standby,ledul clipeste si apoi incet incet dispar toate tensiunile...efectiv moare cu totul....
