Drop Knowledge

Have an OG Droid that I unfortunately dropped on a friend's kitchen floor, cracking the screen in several places. Had an LG Ally as a backup and am currently using this phone.

Ended up ordering a replacement screen on eBay, since the Droid was still functional, just hard to read in some places. Got everything taken apart, replaced the screen, and reassembled.

Problem is that the phone now powers on, but the backlight of the screen doesn't come on at all, making it virtually impossible to read/make out anything on the phone's screen.

Anyone know what I might've missed/screwed up when putting the phone back together? Currently looking to upgrade anyway, so it's not a big deal, but this is still irking me.
