The MacBook Pro M1 13-inch (A2338 – 2020) uses an ultra-thin LCD flex cable routed through the hinge, connecting the logic board to the Retina display panel.
Due to its folding design, the cable may suffer microfractures over time, resulting in flickering, intermittent display, or complete backlight failure.
Symptoms include screen turning off when the lid is opened at certain angles (known as “Flexgate”), or flickering when adjusting the hinge position.
Replacing only the LCD flex cable is a cost-effective solution when the LCD panel, camera, and sensors remain intact, avoiding full display assembly replacement.
The repair involves carefully removing the display, isolating the faulty cable, and replacing it with an OEM-grade part using specialized adhesive and anti-static tools.
