Locate the 30 mm, Phillips head screw in the upper-left corner of the midplate and remove it.

There are two 30 mm, Phillips head screws on the bottom side of the midframe. Locate and unscrew them.

There are two more 30 mm, Phillips head screws hidden on the right side of the midframe. Locate them and carefully remove them.

The ribbons are in close proximity to the hidden screws. Be careful not to nudge them in any way.

Once all the screws have been removed, gently lift the midframe to reveal the circuit.
