Locate the two connectors at each end of the FPC.

Use the flat edge of a spudger tool or your fingernail to gently pry each connector straight upwards out of its socket, then remove the FPC cable from the unit.

You should now see the yellow-colored strip on the metal base marking the location of the FPC
