Unfortunately, the situation is the same. The voltages on the board seem correct except for the lack of 3.3v to the EDP at power-up.
Serial number is: YX02EEZY

You have to solve the problem of lack of power, bios cannot replace it.

3.3 v next to the EDP switch is there, but no one controls it. I will look at the diagram again.
I have also tried with a monitor on the HDMI port - no picture.I do not rule out the possibility of damaged memory that is soldered to the mainboard.
Num Lock and Caps Lock are also unresponsive, for this I went to bios or ec dump IT8987E

Hardware wise everything looks normal. Still looking for bios or ec dump.
