Apple launched the 13-inch MacBook Pro Display Backlight Service Program to address an issue affecting certain MacBook Pro models where the display backlight may exhibit unexpected behavior. Specifically, impacted devices may show vertical bright areas along the bottom of the screen or experience a complete backlight failure. This issue, often referred to as the “stage light effect,” is caused by a flex cable problem that connects the display to the main logic board. Over time, repeated opening and closing of the MacBook lid can strain the cable, leading to malfunctions.
