Da, invertorul e pe sursa. Controlerul este BA9741F. Cred ca 3 lampi sunt defecte. Le-am verificat cu testerul,numai una lumineaza bine.  La pornire ledul incepe sa palpaie la intervale de 5 secunde. Cred ca din cauza lampilor defecte intra protectia in functiune. Tensiunile de 12v si 5v sunt ok. Chiar daca decuplez alimentarea invertorului, ledul palpaie in continuare.Asta denota ca lipseste sarcina )sau este mica) la iesire
