I've swapped out the screen on many broken SE's past for a quick and relatively easy fix for my (now vintage?) SE. Sadly, this procedure no longer fixes the digitizer- the screen and everything else works though- it just doesn't react to touch at all. What, besides the screen/digitizer assembly could be the culprit now? Would love to revive this snazzy old phone of mine! Thanks for any help!

I've done this repair lots of times, but finally have damaged my trusty SE's digitizer somewhere beyond the screen assembly. The screen & buttons all work fine but not the digitizer- i've tried two assemblies. What else could be wrong? I guess the connector?
