Use a pair of tweezers to slide the digitizer cable horizontally out of its connector on the game card reader board.

Before inserting the cable during reassembly, make sure the ZIF connector locking flap is flipped up.

With the cable parallel to the board, gently slide it into its connector.

Don't force the cable into the connector. If it doesn't insert, ensure the locking flap is flipped up, reposition the cable, and try again.

If your touchscreen doesn't work after the repair but your Game Card reader does, make sure this cable is properly inserted. If your Game Card reader also doesn't work, check the Game Card connector in the next step instead.
