If the screen on your MacBook has broken with lines displayed, don’t repair in the first place.Try to diagnose by yourself and find possible solutions. It is possible that accidents like this are relatively cheap and easy to fix. A repair from Apple is not the only option you have, especially when your MacBook is out of warranty.Moreover, if the lines on your MacBook’s screen are caused by accidental damage such as got dropped, Apple will not cover the cost for fixing. In this tutorial, we will help you to diagnose and repair MacBook screen lines.
Step 1: Diagnosing Hardware or Software Cause Screen Lines on MacBook
To diagnose if it is a software or hardware, try connecting the MacBook to an external monitor.If the external monitor displays the screen properly, then your MacBook must have the problem (It's a hardware issue). If both the external monitor and the MacBook still show flickering lines on the screen, it is a software issue.
Step 2: If It is Software Problem
Check any new software you've added, including MacBook OS software updates, to see if they have any known issues with your MacBook model or with software you're using. Restart your MacBook in normal mode, and then run your MacBook with only basic apps, such as email and a web browser. If all works well, add any apps you use that may have helped cause the MacBook screen lines issue one at a time. Continue until you're able to repeat the problem, which narrows down the software cause.
However, if you still have graphics issues without opening any apps, and the graphics issues were gone when running in Safe Mode, try removing startup items from your user account, or create a new user account for testing.
Steps 3: If It is Hardware Problem
1. Try to Use An External Monitor
There are plenty of monitors out there at reasonable prices which will allow you to still use your MacBook. To attach your MacBook to an external monitor you may probably need a Mini-Display to VGA Adapter. You can buy a brand new one from Apple. Alternatively, there are also non-official adapters, but these may not work as smoothly. However, the method of using an external monitor and connecting it to your MacBook is only really a short term fix for MacBook screen lines appearing.
