Please help me diagnose Asus FX505DY Rev 2.1
Was a water damage problem, turned out GPU main power rail (vddc_lx2) is faulty. Replaced a MOSFET at PQ9202. Now it's turning on, plt_rst# 3.3v, checked the ram also fine. But, it's turning on with full speed RPM fan after some reset and no display.
spi_CS# pin 1 = 1.8V
spi_DO pin 2 = 0V
spi_WP# pin 3 = 1.8V
GND pin 4
SPI_DI pin 5 = 0.01V
SPI_CLK pin 6 = 1.472V (I'm suspecting this one, I think it should be 1.8v (failure to communicate with APU). Tried to remove the BIOS chip and turn it on, that pin goes to 0.723V)
SPI_HOLD# pin 7 = 1.8V
VSPI pin 8 = 1.8V
Maybe BIOS problem? please check my backup (Backup ASUS TUF Gaming FX505DY REV 2.1.rar).
