Once the LCD panel and rear camera are removed, you can begin removing the Power, Mute, Volume cable (hereafter called the PMV cable for short).

The PMV cable starts near the end of the control board cable that runs between two of the battery units, and runs in a complicated path along the side and corner of the iPad. (see photos 1 and 2)

The end of the PMV cable is wrapped in tape. Begin by removing this tape to expose the silver rectangular connector on the end of the cable. (see photo 3)

Use a plastic opening tool or small screwdriver to lift free the rectangular connector.
