Introduction
The display assembly includes the screen bezel, hinges, camera/microphone module, WLAN and WWAN antennas, and the LCD (liquid-crystal display) screen. You may opt to replace the entire display assembly, rather than its individual components to save time. Some common symptoms of a faulty display assembly include a blank, black, or flickering screen, hinges that are stiff, loose, or dislocated, or webcam issues that cannot be resolved by fixing the laptop’s settings.
Make sure to disable the internal battery, power down your device, and disconnect from any external power sources before you begin.
