Next you need to peel the ribbon cable off of the yaw arm. It is sticky, but not too bad. I would recommend using a hair dryer to warm it if possible to soften the adhesive.

Carefully peel it off the yaw arm.

Remove the brown ribbon cable from the circuit board first. This is another zif slot with a tab the needs to be lifted with your fingernail.

after the brown cable is removed it is easier to remove the black ribbon cable.

Set the circuit board aside.
