How to remove black horizontal lines appearing on the screen of MacBook Pro

Hi. I opened my MacBook Pro this morning and when I turned it on I saw my screen full of horizontal symmetric black lines covering literally everything . The pc wasn’t damaged in any way, didn’t fall, didn’t hit anything, didn’t touch water. Does anyone know what the issue can be and how to fix it? Thank you 🙏🏻

Black horizontal lines on the screen can be caused by various factors, such as a faulty display cable, a damaged LCD panel, or a malfunctioning graphics card. Some possible solutions are:


Resetting the System Management Controller (SMC) and the NVRAM.

Updating the macOS to the latest version.

Booting into safe mode and running Disk Utility.

Connecting to an external monitor and checking if the lines persist.


While I can write more solutions here but it’s better if you check out a professional guide with proper steps dedicated to this issue. You can check out this guide on 10 Working Solutions to fix lines on Macbook Screen
