Witam wszystkich,
MSI Katana GF76 11UC-468XPL, MB: MS-15821 rev. 2.0
Laptop się uruchamia, ale brak obrazu na matrycy. Pobór prądu jest w granicy 2,300A i stoi.
BIOS przeprogramowany, brak poprawy.

Napięcie na cewkach:
PL13 - 3,34V
PL18 - 5,05V
PL20 - 1,79V (czy nie powinno by w okolicy 1,05V?)
PL14 - 1,21V
PL12 - 3,45V
PL21 - 0,27V
PL9,10,11 - 0,69V
CHOKE1 - 1,09V
CHOKE2 - 1,01V
PL2 - 1,83V
PL7 - 1,78V
PL3,4,5,6 - 1,79V (czy tutaj napięcie też nie jest za wysokie?)

Proszę o pomoc w usunięciu usterki.
