Disconnect the right ribbon cable. Hook your fingernails behind the right and left notches of the black connector part, and pull it towards the white ribbon cable with even and L/R balanced force until loose. FRAGILE ! The cable will slide out easily.
For reassembly : notice this cable is ON TOP of the black connector wedge. Insert the cable as intended, and push the black wedge back in place, again balancing force left and right.
