Introduction
The control board is an essential part of the display as it is the component that acts as the nerve center that the CPU sends signals through. When those signals aren’t being processed by the control board, that can cause the system to crash.
Before starting the steps be sure to power off the display and disconnect it from any external power source.
What you need
Step 1

- Place the Cinema Display so that it is lying on its face and the feet are pointed away from you.
- Remove the three screws (9.52 x 4.43mm) that connect the back foot to the hinge using the Hex Key.
- Remove the back foot from the hinge mount by grabbing the foot and pulling upwards.
