Wszystkie napięcia na płycie są. Płyta się uruchamia. Mostek i procesor działają ( delikatnie się nagrzewają). Dysk startuje.
Jednak nie ma obrazu na matrycy. Po HDMI też nie ma obrazu.
Brak napięcia na FUSE3000 - przypuszczam że zasilanie matrycy ( brak schematu w sieci)
Wymieniłem układ U3302 (PS8625).
Sprawdzałem na różnych wersjach BIOS.
KBC wymieniałem.
Brakuje mi już pomysłu. A niestety nie ma nigdzie schematu do tej płyty.
