Touch screen not working after screen replacement

Touch screen not working after screen replacement

Just replaced the touch screen on a friend's phone, and it's completely unresponsive, LCD works fine though. Old screen is also completely unresponsive with LCD working. Anything I can do to try and fix this or did I bust the connector on the motherboard itself?

I would closely inspect the connectors for the digitizer on the logic board (look here) as well as the surrounding area for any tiny components that may have been knocked off. Magnification is important here as the parts are tiny.

It's most likely the touch filters located blow the connector. https://youtu.be/kk3mYfngY6c

the touch Ic chip seems to be the issue. have come across this issue in my travels, it is a rather quick repair
