Horizontal pixel lines in Yosemite

Got this issue today, any updates? I need help plz

I also just got this issue. faint horizontal lines appear every 20 or so pixels, and are approximately 1 pixel wide. This is the retina screen. Even the initial boot-up "Apple logo" shows this.

Any confirmation of the source of the problem?

- software only?

- video firmware?

- hardware defect?

Apple?? Help here!

Yup, me too. Just started yesterday. Weird and so annoying. Apple!

Made an appointment at Apple Store -- going back for repair under warranty. Confirmed hardware defect.

Those are bad news for me, I'm live on Venezuela and my mbp-r is out of warranty (may 2015). In my country we don't have a good apple support. And is too expensive (more than US or other first-word countries).

Bad bad apple.

Keller, that is indeed bad news :-( Sorry! Is there a service center you can ship it to for repair? When I signed for this repair under warranty, I saw the cost: close to $350 for the screen replacement.

When I get it returned, I'll provide more details. Hopefully it will be successful!

Yes d1d, is annoying-frustrating to be in this situation, I have a good (and expensive) computer, and after only one year i got this issue. The worst is that I was very careful with this mac. 😢

Thank you for your help d1d, don't forget me. When you'll get your mbp-r repaired, let me know the cost plz, maybe a friend or familiar, can travel to US this year and carry my mbp-r to an apple service center.

I have an unfortunate issue 😟 mid 2008 MacBook that I upgraded a few months ago to 8GB RAM, new battery, hard drive.. now I've got a single line about 1/3 up the screen that's dead as of about an hour ago. I also am running Yosemite and have an additional monitor.

Has anybody found a fix that doesn't involve taking it into the Apple store?

Thanks!

I have this problem on my mac where horizontal lines run across the screen (pixels not dead, but dimmed, every 2/3 pixels there will be a dead row). This happened after Apple replaced the anti-reflective screen. Urgh! MacBook Pro 13 inch (Retina, Late 2014). Seems like the same problem.

I also seem to have this problem where every 2nd pixel line horizontal is dimmed down just a bit, you have to look closely. but its there! its simply not acceptable on a Retina screen, and there must be some answer to this? It came with an update to the OSX but dosent seem to be there in the black and apple logo startup screen. But appears when i have to login... Come on apple

I have exactly the same issue on my only 1 year old Mac. Manufacturer warranty just ran out... 😟.

The issue just happened from day to the other. Can anyone give advise on what the issue actually was? Hardware or Software fault?

It would be really annoying if there is an issue with the hardware and I have to pay for it. As the macbook only sits on the table and there should be no reason for anything to break with the screen.

FYI - I've upgraded to El Captain and that didn't resolve the issue with lines.

ManuSchi84, I think is a hardware issue, I cannot repair my mbp-r, because I'm living in Venezuela, but the issue is related to the retina screen itself. Another user reported he was sent to apple store and they fixed it replacing the screen. I'm living with issue for almost a 1 year right now.

Thank you for the advise! Much appreciated. It's quite disappointing though in the built quality - my macbook pro is just over 1 year old... now I have to pay to get the screen fixed. Expected more from Apple...

I have this problem on my MacBook Pro (Retina, 15-inch, Late 2013).

I'm from Brazil and here is very expensive to repair. I believe this is a serious hardware problem. Many people with the same problem.

Apple could admit these events 😟

Hi.

I am having the same issue !

Did the screen replacment fix the issue ?
