N3DSXL only turns on with blue light then shuts off.

Hey all. I am repairing a N3DSXL and replaced the bottom screen with a replacement from ebay. Unfortunately, the 3DS won't turn on when I try to boot it up. It turns on with the blue power light and the bottom screen can't really turn on and a slight 'pop' is heard.

Here is the screen I replaced it with:

I did take it apart several times more to check for loose ribbon cables but, no dice. Any ideas what it might be? The screen seems to differ also in that it has one less gray-ish connector on the top. But, that's just what the replacements seem to look like. Everything is connected properly and I didn't forget to connect anything. Could I have connected one of the ribbon cables found underneath the motherboard incorrectly?

Thanks!
