Unscrew the ambient light sensor cable bracket

Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.
Use a Phillips screwdriver to remove the two screws securing the ambient light sensor cable bracket to the logic board:
One 1.3 mm screw
One 2.0 mm screw
During reassembly, this is a good point to power on your iPad and test all functions before sealing it up. Be sure to power your iPad back down before you continue working.

拆下环境光传感器排线支架的螺丝

在整个维修过程中，请记录每颗螺丝的位置，并确保它们准确地回到原位。
使用十字螺丝刀拆下将环境光传感器排线支架固定在逻辑板上的两颗螺丝：
一颗1.3毫米螺丝
一颗2.0毫米螺丝
在重新组装时，这是一个很好的时机，可以在密封之前开启iPad并测试所有功能。请务必在继续工作之前关闭iPad电源。
