If you have not already done so, disconnect the two bottom-LCD ribbon cables from the main board by prying up the black latches and pulling the cable out to the side.

The ribbon cable (marked in blue) for the touch screen is particularly thin and fragile; be careful to avoid bending it more than necessary.

Flip up the latch and remove the touch screen cable.

Flip up the latch and remove the top-screen ribbon cable.

Pry up on the orange cable to disconnect it from the main board, much like the antenna cable on the Wi-Fi module.
