avico, Thank you for posting in the Intel® Communities Support.


In reference to " I can't locate boardview or schematic anywhere,", in the following link you will find the mechanical drawings of the Intel® NUC Kit NUC6i7KYK, please look for the "Intel® NUC Kit Drawings" tab, once you get the chance, please let us know if that information was useful for you:

It didn't help much to me, These files only has 3D board and case designs.
Thanks

No, the OP won't find anything pertinent there.

The development team is telling me that the fried part is a PL528 inductor. 

Hope this helps,

Thanks, thank to you I Know nos that it's a inductor, but I continue whitout Know the value. Thus afternoon I was investigativo about the close circuit labeled 6J=3G that is because the inductor burst. This integrated circuit is called RT6220AGQUF and you can found it by google. Now only has to Know What is the inductor value, if I Don't locate it I Will put some similar to others inductor the board.
Thank you very much.

They're telling me that it isn't an inductor (I presumed that because of the 'L'). They are saying that PL528 is a ferrite bead, 70ohm @ 100MHz 0805 rated for 3A.

Thank you for the info. 

The ferrite bead is connected directly to the power jack (19V). Is this normal? Or maybe some other component caused that voltage thus causing the burst?

So did you run this hot or did it blow on a normal setting?  Just wondering, because I'm starting to worry that high-end NUCs run too hot!

Here's a response from the development team:

Yes, it’s normal that it’s connected directly to the 19V input. It’s part of an input filter for the RT6220 voltage regulator also mentioned in this thread. Replacing the ferrite bead may or may not fix the issue. The ferrite bead could have blown because something else downstream died or shorted and the ferrite bead was the weakest link in the chain so to speak. Assuming the unit is out of warranty at this point, I’d say it’s worth a shot if you feel competent to do the soldering rework. It can’t make it any worse.

Hope this helps,

Wow I wouldn't expect such an "embedded" support from Intel or any other brand. Thank you so much. I bought 5 RT6220, and I managed to solder one of them, but same result. I will try again as soon as I get more precise equipment.

 

Thank you!

I was a part of this team before I retired, so I know where they live (literally).     ;^)

Let me know how it goes...
