Ghost Touches / No touch response after repair

Hi guys,

I just replaced the charging port on my Xperia X compact. With the replacement all set, i reassembled the phone. It would charge properly, but the screen wouldnt respond.

After a second disassembly to check all connections (all in place) I am experiencing ghost touches all over the place.

Any ideas for a fix?

Please note: Had to remove a plastic cover for the screen-connectors with the first dissassembly. Figured this might be an issue but had the same troubles when holding screen and mainboard “separately”.

Thanks for your help!
