#1 Asus TUF FX505DY REV 2.1 - po zalaniu, brak obrazu

Cześć,

CPU AMD Ryzen 5 3500U
GPU AMD Radeon RX 560X
KBC IT8225E-128
BIOS MXIX MX 25U12873F

Laptop trafił do mnie po zalaniu martwy.
Zalanie występowało w rejonie KBC oraz układu RT3663BCGQW, który to wymieniłem od razu wyczyściłem wszystko i wymieniłem podejrzaną drobnicę w koło. Po tych zabiegach laptop wstaje próbuje się uruchomić, reaguje na włącznik, ładuję baterie lecz nie ma obrazu.
Bios i RAM podmieniałem bez efektu.
Na termowizji nagrzewa się procesor równomiernie, GPU nie startuje. Wentylator od GPU cyklicznie próbuje wystartować lecz za chwile przestaje. Natomiast wentylator od CPU po chwili wchodzi na maks obroty.

Napięcia które występują:
PL8901 8,6V
PL8601 1,22V
PL8701 5V
PL8702 3,3V
n.8 BIOS 1,8V
PL8104 1,03V
PL8101 1,15V
PL8102 1,15V
PL8103 1,15V
PL8301 0,9V
PL9401 0,9V
PL8401 1,8V

Na cewkach od GPU brak napięć.

Proszę o pomoc w dalszej diagnozie.
Pozdrawiam.
