MSI GV72 MS-16j91, dead, no SUS_ON

[t34v2]

MB: MSI MS-16J91 ver 1.0
CPU: i7-7700HQ SR32Q
PCH: SR30W
GPU: nVidia N17P-G0-A1
KBC: ENE KB9028Q C

No response to the power button (3.3V present on the button).
After pressing the button, the +3VSUS/+5VSUS converters should appear, but this does not happen.
KBC does not issue the SUS_ON signal (PU4 pin6 and pin20 = 0V).
+3VALW and +5VALW present.
Choke11 (+3VSUS) = 0V, 4kΩ
Choke10 (+5VSUS) = 0v, 11kΩ
I inserted another KBC programmed for this board - the same result.

I have placed KBC chip to another board and reprogrammed it (Acer) and it works, that exludes KBC failure.

KBC measurements:
22 = 3.29V
95 = 0V
100 = 0V
108 = 0V
110 = 3.29V
117 = 0V
121 = 0.05V
127 = 0V

114 = 3.29V (When PWR button is pressed 0V)

RTCVCC (D13) = 3.01V

PU2: (AC connected, battery disconnected)
5 = 3.29V
6 = 2.74V
11 = 3.29V
12 = 3.29V
24 = 5,98V

PU4:
pin6, pin20 = 0V (SUS_ON)

EC_RST KBC pin#37 = 1.55V
LID# pin#53 = 3.29V

Is EC_RST KBC suposed to be 1.55V?

Im looking for help to figure this out. Thanks!

I have figured it out.
EC_RST# should be 3.3V. Voltage drop on this line was caused by damaged diode ED12.

Board works now.
