Touch Screen not Working After Replacement

Hi ,

I’ve recently went to replace my 5s’ cracked screen to a new on only to discover that the touch on the new screen was completely unresponsive. Thinking I had a dud screen, I sent it back and got a refund.

I tested my original screen with my phone again and the touch worked fine.

Ordering a new screen again, I went to install it today and again the touch is completely unresponsive! The new screen is an original apple screen so I doubt it is faulty the second time, however I doubt my phone is faulty due to it working fine with the cracked screen.

Honestly any help on this would be appreciated, because im stumped.
