Broke Calble latch replacing motherboard

[pfeerick]

Now my phone turns on but the touchscreen doesn't work.  Is there some way to fix this? 

I don't know that connectors purpose off hand, but it sounds like from your description that it's the ribbon cable for the touch screen... so you're in a bit of a pickle! I would be pushing the cable flat to the board, and seeing if it still works... not sure the best way to fix it... basically you need something that is keeping the contacts on the ribbon pressed to the board connectors contacts...
