New 3DS XL won't turn on, no blue light.

So the story behind this, is that I ordered a replacement screen and did the whole process and I've done some of these before with no issues. But when I tried powering it on AT FIRST I got a blue light pop sound, so I reseated the top screen ribbon cable and tried turning it back on, but NOW, I am not getting any light at all from it.

I noticed the 53 pin ribbon cable connector, on the middle left side of the motherboard, looks like one of the pins is gone (picture below), but I am not 100% sure if it is just like that or not. I would just like a second opinion on all of this.

Here's some things I ruled out:

I did not put the battery in backwards I know that for a fact.

I tested with my multimeter and do get power from the daughter board to the main motherboard.

F1 and F2 Fuse are good

And the power button was tested with my multimeter and works.
