The board is perfect, all clean! Turn on, fan goes maximum, but no post

RTC_RESET_L - 3.26V
SHP_INTRUDER_L - 1.65v
PCH_INTVRMEN - 2.5v
SHP_SRTCRST_L - 3.26V

PPBUS_G3H - 8.6
PP3V42_G3H - 3.4v
PPVRTC_ - 3.3V
PP5V_S5 - 5v
PP3V3_S5 - 3.3V
PP3V3_SUS - 3.3V
SMC_ONOFF_L - 3.37v

SMC_ADAPTER_EN - 3.3V
SMC_PM_G2_EN - 3.4V
PM_BATLOW_L - 3.3V
PM_PWRBTN_L - 3.4V
PM_RSMRST_L - 3V (board turns off when I check)

Is a clean BIOS a good test?

Do you get CPU core voltage?
PLT_RESET_L comes on?

"SHP_INTRUDER_L - 1.65v"
Supposing you mean PCH_INTRUDER_L, this denotes a problem with PCH.
You can try to heat it, using quality flux.

CPU - 1.65v
PLT_RESET_L - 3.3v

Yes, it was PCH_INTRUDER_L =D

I tried to warm it up, but it worked.
