Model 22PFL3403/10

la actionarea butonului on/off ledul de st-by se aprinde/stinge, se vede ca lampile lumineaza pentru o scurta perioada de timp si atat. Nu afiseaza nimic(sigle/menu....)

Tensiunile surse par a fi ok (+12V / +5V) exista, cei drept inca nu am masurat parte de invertor

Un sfat de unde sa incep ar fi bine venit

Ati spus: lampile lumineaza o scurta perioada de timp. Poate intra protectia invertorului. Incercati sa vizualizati, in scurta perioada, cum se comporta lampile. Cel mai bine ar fi, pentru probe, sa anulati protectia inverterului si sa constatati in ce stare sunt lampile. Si o descarcare la masa poate cauza acelasi defect. Idem contacte la lampi oxidate, coclite etc.
