#1 Xbox 360 Winchester nie reaguje na włącznik

Konsola nie uruchamia się, zero reakcji na włącznik, wstępna diagnoza brak napięcia 3,3V. Wymieniłem układ U5A1 jednak nadal bez zmian, nie ma żadnej reakcji na włącznik.

Model płyty X879957-004.

Dioda led na zasilaczu cały czas świeci na pomarańczowo.

Poniżej pomiary których udało mi się dokonać względem masy już z nowym układem U5A1.

Witam czy może mi ktoś powiedzieć czy wszystkie napięcia są odpowiednie czy może jakiegoś brakuje? Co może być jeszcze przyczyną, że konsola się nie uruchamia.
Jest może gdzieś dostępna rozpiska napięć standby, które mogę jeszcze dodatkowo pomierzyć, aby zdiagnozować usterkę. Byłbym wdzięczny za pomoc.
