Help! Nexus 7 2013 repair failure! Broken motherboard

So last night i dropped my tablet and the screen had cracks all over it, well i watched a bunch of tear down, and screen repair videos on youtube, then tried to take it apart to fix it myself. But when i tried to remove the silver motherboard ribbon cable, the white connector broke off of the motherboard. :crying: :crying:

Note that warranty expired several months ago.

What should i do? is replacement motherboard and screen assembly worth it?
