Sigma Board - U53 Burnt + Not Booting up after

Hello All, 

I am a newbie and this is my first post here. The U53 IC on my board with a couple of components around is burnt (see pic). After this, on powering up, the Blue LED glows constantly and the Fan is not running. I tried connecting the HDMI but my monitor does not detect any change at all.

I could read IT8856FN on U53 and it looks like a USB Type C PD 3.0 controller. I had connected the same USB Port in Thunderbolt mode for display.

I request for your help / suggestion on further steps.

Thanks in advance.
