    Asus TUF B450M Pro S missing Vddq fan spin no lights

    Board was fine when I put it into storage in antistatic bag, was helping a friend build a system with spare parts. Used a R5 1400 (tested) and it didn't post. Tried to downgrade bios with flashback, now no lights at all, just fan spins.
    I saw a video of a similar issue on an Asus Mobo, long story short he has no VDDQ and it was due to a bad transistor driven by P_VDDQ_SIO_EN_10. I don't have any post card or ddr voltage tester but I can see I have no voltage at VDDQ or SIO_EN either. Am I walking the right path to fix this? Is the SIO chip bad perhaps?
