G751jy led backlight problem/mobo

Hello everyone.

The problem is as follows:

I took apart my G751JY down to the last bolt, however when I put it back together the screen was not working. The external monitor works but the LCD screen remains black. Tried holding the power button for 20 - 45 - 60 seconds, does not help. Tried unplugging/plugging in the screen - does not help. Took apart the screen nothing special there. Took apart the laptop again, and on the bottom of the mobo found out that a certain part was fried (see pictures)
The screen is black/does not show signs of life, however when pointed at with bright light I can pick up details.
What caused the problem? (my thought) -When taking the laptop apart i disconnected screen prior to disconnecting the battery (since the battery is internal I unhooked the LED screen connector first and only then saw the battery connector - my mistake I know).

The only problem is the LCD backlight, everything else works great - GPU,CPU, RAM, charging etc. Just the backlight does not.
I need your help to figuring out what kind of part is this and if it is possible to fix it? I know its hard to pick it out from pictures but maybe someone has seen this before. Any ideas will help! Thanks!
