#1 Acer Predator Helios PH317-55 płyta LA-L181P identyfikacja elementów po zalaniu

Cześć, trafił do mnie laptop Jak w tytule, płyta główna GH51G LA-L181P rev: 1A. Laptop po zalaniu widocznym na zdjęciu. Po oczyszczeniu uruchamia się, ale nie wyświetla obrazu, stoi na poborze 1,2A, nagrzewa się bardzo mocno SRKMA FH82HM570, nie jestem w stanie utrzymać palca na rdzeniu, czy to normalne czy raczej uszkodzony na skutek zwarcia w wyżej wymienionej strefie?
Proszę o pomoc w identyfikacji skorodowanych elementów, są to kondensatory (oprócz jednego rezystora 4R7), chyba, że wartości uF nie są istotne w tym miejscu?
Pozdrawiam

Nie podłączaj zasilania do płyty zanim nie wymienisz skorodowanych elementów.
