Use the flat end of a spudger to lift the display cable connector up out of its socket.

Only pry up on the display connector itself and not the socket on the motherboard.

At this point during reassembly after the display is connected, turn the phone on and verify that the display functions correctly. If it does, turn the phone off and proceed with reassembly.

If it does not work, check that everything is assembled correctly and the connectors are clean. For further troubleshooting, visit our Answers Forum.
