Faint horizontal gray lines on macbook air screen

Faint horizontal gray lines appeared out of nowhere on my screen. There's nothing I can think of that could've caused this issue (I have never dropped my MacBook, I'm certain it never overheats, and I have not installed anything not supported by Apple).


I haven't encountered performance issues along with the lines, it's just very annoying and distracting to see everything covered in them.


I've found some other posts (2, 3, 4) of people with similar issues and it seems to be a random issue on some MacBooks (I'm certain there are more people with this kind of problem). It's really frustrating given the price you have to pay for one of these. I don't know how much fixing it could cost me.


Has anybody else encountered this problem and has been able to fix it? If so, how?

MacBook Air 13″, macOS 13.5

Troubleshooting Grey Lines on a Screen:


Yes. I've been through something similar...


During the Pandemic...

A little bit of a story for you: My 2017 MBP's screen went dead and I sent it in every time --ending in 11 send-ins. Eventually I wan granted a free upgraded Mac, being I was so patient and respectful to Apple (in recognition of how not all customers are respectful and helpful on a bug). So, send this in 11 times (seems ridiculous, but so) and maybe they'll do the same for you. So, be CoolCalm, and Collective, and you might just luck out like I did. A User Tip of Mine: Send-In Service - Include Handwritten Notes with the Packaging - User Tip


So, what to do...

Get this Diagnosed by Apple:

Your screen is failing. Apple might fix it free of charge, if found to be be faulty device. Set up a Genius Bar Appointment at your local Apple Store. There, it will be looked at and you'll be provided with your options.
