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

water damage was mostly around PU2 that doesn't let it to turn on
and allitle around pu8 (pr121) that doesn't make cpu voltage

i thought SYS_PWRGD = 1.8V means that all voltages are good
also HWPG= 3V
Voltages on all coils are good

resistance for pl16=32ohm and pl11=148
its amd E1 cpu

Does the voltages rise on PL11 & PL16 ?

if yes, did you try to flash the bios ?

do you have "U18" installed on the board ?

yes i flash some bioses and same result

PL11=0.90V
PL16=0.84V

no there is no u18

and my board is UMA

Check the resistance of USB D+,D- lines,

if they are not in low resistance try the attached bios..
