#1 VTX3D Radeon HD 6770 1GB DDR5 - brak obrazu

Witam,

jest to pierwsza karta graficzna, którą chciałbym spróbować naprawić. Karta pochodzi z komputera w którym doszło do zwarcia w gnieździe pamięci RAM. Wentylatory GPU startują, sama karta nagrzewa się. Wiem że opłacalność naprawy jest żadna, ale jest to sprzęt przeznaczony do nauki.

Pomierzyłem rezystancje na cewkach; wszędzie jest wysoka z wyjątkiem L700 (33Ω). Wizualnie nie widać żadnych uszkodzeń. Chciałbym zrobić próbę zwarciową na zasilaczu serwisowym, ale nie mam pewności w którym miejscu mogę podać napięcie.

Będę wdzięczny za pomoc i wskazówki.

Oznaczenie płyty: 109-C01037-10; MODEL C010
