MacBook Screen Lines, Flicker or Black Display
Learn how lid angle, external video and visible damage help identify a display problem.
Stop and seek help: Disconnect power if you notice battery swelling, liquid exposure, smoke, a burning smell, severe heat or damaged charging contacts.
Describe the image precisely
Vertical lines, colored blocks, ink-like black patches, a dim image and total blackness point to different failures. Photograph intermittent behavior when possible. Note whether the issue changes as the lid moves.
Try an external display
An external monitor can help distinguish internal display trouble from a system that is not producing video. A working external image does not prove every logic-board video circuit is healthy, but it is useful diagnostic evidence.
Avoid closing a damaged panel
Cracked displays can worsen when pressure is applied. Do not place objects between the keyboard and screen. If the hinge or case is bent, avoid repeatedly opening and closing the lid.
Why the complete model matters
Display assemblies differ by size, year, color, camera hardware and connector design. The serial or model number is needed before ordering a compatible replacement.
