Remove the long flex cable (red box)

Note the exact orientation--the horizontal metal stripe (see the green box) is offset and must be reinstalled exactly the same way

Be careful with the flex connector latches which are quite fragile. Slide them parallel to the cable using a fingernail or a guitar pick.

Remove the two 90 degree flex cables (orange boxes), again being sure to record their exact orientation and location.

During reinstallation of the 90 degree cables, it is easier to install them in the top and bottom circuit boards first.

Disconnect the flex cable on the far right (blue box).
