hi guys this board has water damage and it was almost dead in first place i turn it on and now it has all voltages on coils but there is no display. lvds or hdmi post code is 01 SYS_PWRGD = 1.8V RSMRST#=3.2V RSMRST#_R=1.9V how can i find is it cpu problem or what? as i make it alive from total death i really want to repair it ill be grateful of your helps thanks all |

Where was the damage in which area ? measure and post the voltages and resistances across all the coils.. |

not enough information. few measurements. and the resistance of the processor https://comsystem-tlt.ru/obzori/soproti ... processoro |

Does the voltages rise on PL11 & PL16 ? if yes, did you try to flash the bios ? do you have "U18" installed on the board ? |

Check the resistance of USB D+,D- lines, if they are not in low resistance try the attached bios.. |
