  • Pull up the “A/V OUT DIGITAL” cover and remove the screw above the USB port.

Note: The PH000 bit from my iFixit toolkit fits the screws better than the PH00 described above. The 00 bit is too pointed to bottom out in the screw and therefore does not engage as well.

  • Carefully unhook the “A/V OUT DIGITAL” cover from the hinge.

With the camera I was repairing, to remove the front cover as shown below, it was necessary to first remove the two smaller screws on the opposite end of the body from the “A/V OUT DIGITAL” cover. That is . . . the screws shown in step 5 which in my camera also hold the front cover in place (design change apparently).
