Need Schematic Intel Nuc DC3217IYE

[totof]

Hello.
I need SCHEMATIC INTEL NUC DC3217IYE

Problem : the pc nuc power on but screen is black (no signal). Voltage 5V, 3,3V, 1,34V (RAM), 1,06V (CPU) are good but 0,02V on another "unknown" coil (coil near CPU coil)

Thanks for attention

No schematic for this board ? :-(

I have the same issue with the same board. Also the coil voltages and the 0,02V
I have also another working example and there I can measure 0,85V on this coil where there is 0,02V. It drops to 0,78V with hdmi attached.
On your photo there is another big coil near the hdmi, but there I find 0V also on the good board.
And on the other side of the board another coil near the battery connector with 1,5v

My broken device was running hot and not always rebooted normal. Therefor was always on, but recently it was powered off for some days, and since then no signal no more.

I was thinking of a bios issue, I tried these steps https://bytespeed.com/nuc-bios-recov...curity-jumper/
but no luck,
Oddly these jumper method is mentioned on the Intel site but the link is not working anymore

under the heatsink there are 3 more coils, on my working board the 1 closest to the powerbutton shows 1V , the other 2 both 0,8V. On the broken board the 0,8V is not present, that is cpu vcore. I suspsect the dual n-channel mosfets are maybe broken.
The working board takes about 550mA, the broken only 250mA.
