Cześć.
Oznaczenia na płycie Q5WVH LA-7912P rev: 1.0. Brak obrazu po włączeniu, pobór prądu 0,12A. Za pierwszym razem przeprogramowałem biosy, oddałem klientowi. Po tygodniu wrócił z tą samą usterką. Raz na kilka prób płyta się uruchomi, po czym pobór wynosi 0,12A. Podmieniłem ram, procesora nie mam na chwilę obecną na podmianę. Poniżej podaję rezystancję i napięcia na poszczególnych cewkach i proszę o dalsze wskazówki.
