What did I fry on my logic board?
So. I was changing out my LCD in my MBA when I ran into a problem. After connecting the LCD connector and the LED ribbon, the display would turn on but the LEDs would not. I was almost positive that the LED ribbon was installed correctly, but after hours of scouring the internet, I think I have come to the conclusion that it was actually backwards. The problem is, I can't test that now because the LCD doesn't work anymore. And I think it doesn't work anymore because when inspecting the LCD connector using the "pro" tweezers I bought, I happen to notice a tiny bit of smoke coming from the connector. At first, the computer wouldn't even turn on, but then I connected the LCD and it the computer turned on. At that time I didn't think to see if the LCD was working too. I assumed I was good. By the time I figured out to install the LED ribbon in the other way, it was too late and now presumably something is fried. My question is, how do I figure out what is fried? The whole logical board? Just the LCD controller? I don't know where to start. Any help is appreciated. Thanks.
EDIT: Below is images of the board.
Is this a good question?
