Is the lcd broken or just loose connector?

I dropped my phone, and now the screen only works (kinda) at about 3/4 of its width. The question is: Is the screen broken, or might it only be a loose connector that could be fixed by opening the case and re-attaching it properly?

The glass shows no sign of damage.

Also, I would be grateful if you could point me to a disassembly guide for the phone (note the Moto E 2nd Generation is not built the same as Gen 1)

Cheers,

Lucas
