Default [Q] Replaced screen assembly issue

Hi all,

I've recently replaced my N7105 screen assembly. I am able to turn the phone on, but the screen remains entirely blank. However, it responds to touch and appears to be working - only no image is displayed on the screen.

I suspect I've damaged a component on installation of the new screen, or have incorrectly connected it to the logic board. The replacement screen was from etradesupply and I imagine is almost definitely not an official Samsung component - is their any chance of driver incompatibility?

I've demonstrated the problem and displayed the connectors in this short video:

If anyone has any suggestions, I'd be very grateful.
