No Touch after Screen remplacement

You either have a defective replacement screen or you damaged something during the repair. Go back through the guides and double check all the steps.

Try these steps:

• Double check that the flex connectors are properly seated
• Visually inspect, preferably with magnification, the condition of the connectors on both the flex cables and the logic board
• Also look to see if any components appear missing or damaged
• Try connecting the original screen to see if the problem is consistent with the screen or logic board.
