What is this burn on my logic board?

downtoretail, that image is very difficult to interpret. You should consider posting a couple of better once. right now it looks like your EMI shields got discolored from some heat. I suggest that you remove it and take a look on how many bad/destroyed components you will find under there.

Wow! Thankyou so much for actually replying - it really means a lot!

I'll google how to do that, thankyou!

Here are some more picture I took: http://imgur.com/VjZACbJ,omECOXe,jt3sAJG...

It looks the same as when someone spills petrol on the floor; that purple-ly swirly look. But it's only near the 2 things that look like vents

The area with the vent holes is where you have your backlight driver as well as your memory IC's. So you definitely need to take a closer look under the shielding.
