13" MacBook Pro 2017 - Blinking horizontal lines at the top of the screen

I have this problem too on my 2018 MBP. Went to an Apple store, the genius said it would be $500 without even running a diagnostic. The thing is I'm not sure it's a completely a hardware issue though, because it runs perfectly fine with safe mode and also…with bootcamp. Also, Apple Diagnostics doesn't detect any problem.

I tried to install big sur beta, the problem didn't go away. I'll see if the problem goes away by the final release of Big Sur. If it doesn't, I will only run windows on my Mac. But at some point, I'll probably buy a real windows pc, as they're far cheaper while being just as reliable, if not more.

I'm using a MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports) and have the same issue. It works fine for the first 15-20mins and then the lines start to appear. It only gets wider and wider as I continue using it. Tried resetting SMC, NVRAM, ran diagnostic test (found 0 issues), booted in safe mode (issue still persisted meaning that it's not a software issue) and nothing works!

Looks like a lot of 2017 macs are having the same issue. Apple should start a service program to fix this similar to the 2016 backlight issue!

Hi! I'm having the same issue with my 2017 macbook pro 13' with 4 USB C ports. I'm a full time student heading to grad school and was expecting this computer to last at least 6-8 years. Now after 3, it's acting up. I can only see what's on my screen normally when I close my computer 1/2 way. I too would love for an apple representative to answer this question and give some answers regarding a repair program! Especially considering that there are 8+ pages of people reporting the same problem a the time of writing this.

I know this is NOT a software issue as I have connected to a desktop/ second screen and the desktop remains free of lines while my MBP does not. It's definitely a hardware/ connectivity issue.

Yes, I don't think it has anything to do with the screen itself because lines vary depending on the usage. It is not consistent; one thing I would also recommend to keep the charger plugged in. I have a strong feeling since these laptops are a couple of years old, batteries are not strong enough to keep up all the system running, and once you unplug the charger, something happens with the video card.

Same problems horizontal lines an ghosting on my Macbook pro tb 15" 2016 , Obviously flex cable related . this only happens when open the lid past 80 degrees. If I go down les that 80 degrees no problem . No problem with external monitors also so gpu is not the problem .

This laptop had every problem you can imagine, hoping sound coming from the screen hinge, sticking butterfly keys, and now this horizontal lines on screen .

I will take it today to see want apple techs have to say . I paid also apple care , but now its out of warranty.

I also have the same issue with my 2017 MacBook Pro with retina and Touch Bar it gets really hot then the horizontal lines start with over lapping I have to turn off and let cool for a long while the it goes away but reappears after about 20 to 30 minutes of use it is disappointing to have spent so much money to get a laptop that really serves no purpose if you can only use 30 minutes when we are expecting to use as long as we would like to

I have a 2017 13inch 4 port Macbook Pro, 3.1 GHz i5. The exact same problem is happening to me. A set of thin, horizontal, black lines at the top of my screen that flicker. Not visible when I take a screenshot of the area, or if I use an external monitor. I'm disgusted that Apple acknowledges this problem in the 2016 models but not the 2017 models.

I'm also facing the same issue with my 2017 13inch 4-port macbook pro! Discovered this thread only after I posted my question on it here: https://discussions.apple.com/thread/251356447?page=1

The Genius Bar has said it's a chargeable repair and I'll have to replace my display. They acknowledge it's something that happens, but pretty much ends there. I understand they are also trained to deal with such complaints in this manner.

I'm feeling so frustrated after hours on the phone with apple but with no solution except to pay a hefty price to replace my entire display - with no guarantee the problem won't come back either. The other alternative I've heard is to trade it in.

I just hope apple will acknowledge this problem for the 2017 models soon :(

I have the same problem. Vertical black lines at the bottom of the screen. Seems like temperature dependant and appear after 2-3 hours of use. If you put some ice behind the lines will disappear... magic. thank you apple. 2k eur mac book pro 2017 touchpad

I have this same problem. I believe it is the T-CON overheating. This is why the horizontal line disappears overnight after I shut down my macbook pro but starts to get darker again after using it for a few minutes.

I have the same issue on this model. I know for sure the problem is not software related as the lines disappear at a smaller angle, but reappear when the screen is at 90 degrees or more.

Hi erichsien,

Thanks for the reply. I know your machine is important to you. It looks like you have already contacted Apple Support. Apple does offer mail-in repair options that may work for you, so you do not have to wait until stores open. If you think that could be a solution for you, Contact Apple Support.

Take care!
