MacBook Air Flexgate is a display-related issue caused by wear and tear on the flexible display cable that connects the screen to the logic board. Common symptoms include uneven backlighting, stage-light effects at the bottom of the display, screen flickering, or a completely black screen when the lid is adjusted. The problem typically develops after repeated opening and closing of the laptop over time. Repair options may include replacing the display assembly or the affected cable components, depending on the device model and the extent of the damage. Early diagnosis can help prevent further display failures and reduce repair costs.
