Horizontal lines on top and bottom screen

Hi i have huge horizontal semi transparent lines on top and bottom of my 2016 touchbar retina macbook pro 13inch.

Other symptoms includes No audio devices found(cant play sound)

Is there any possible reasons for this? I highly doubt is a software problem.

Looks like you also have the same problem as black bar at the bottom screen!

Sadly your screen is failing! You’ll need to see if Apple will cover it under an extended warranty exception!

Hi Derek and Dan, thanks for replying. thats really disappointing for apple products quality. Apple told me to come in and have a check. Too bad my Applecare expired.

I think the problem caused by loose connection of display to logic board due to heat issues as mentioned by Dan. My mac usually got kept in my car trunk, and i live in a tropical place, temperatures are quite high and humid.

@jason12 - Just to clarify the issue is the diffuser sheets within the screen have curled up in your case the heat did it being stored in the trunk of your car. But I won't tell Apple that ;-} Take a look here MacBook Pro Retina Display Teardown checkout Step 12 which shows the defuser sheets.

I think you can get is fixed under extended warranty! Thats when a defect is found beyond the normal warranty period. Ask the authorized Apple center for a warranty exception I think they will give it to you.

I have the same issue. lines suddenly appeared in menu bar. And i’m out of warranty.

Did they gave you warranty exception?

This seems to be either torn display flex cable or Components out of specs due to age or thermal cycle. Ether way it’s a hardware issue and likely requiring the replacement of the entire clamshell assembly.

@tomchai - So far heat is the only thing that I can equate to this failure. Basically, the defuser sheets become unglued on the back along the bottom and/or top edge so the amount of light is lessoned going outwards though the LCD panel. The two I've seen had the systems cooking in a car and a boat.

Apples efforts to cut thickness with the keyboard and now the display is coming back to haunt them! Between the ribbon cable failures and now the de-lamination of the sheets.

Interesting, first time seeing an optical issue on Macs. Apple really messed up on recent Mac models, problems everywhere.

i have the same issue on my Macbook 15" touch bar. Suddenly horizontal flickering lines appear at the bottom part after long usage. I run hardware check but found no Fault. Ive been using for a year and a half. I have an old macbook pro 2010 but never have this problem. I think its because new models are getting thinner so it cant dissipate the heat properly and its causing this problem

my MBP 13" Touch Bar have the same issue

HI Jason,

Indeed this is likely not a software issue, but it can also have multiple source causes. For the 2016 models, this is unfortunately a common problem.

In most cases, I would suggest possibly a failing GPU which likely means that Apple would have to replace the logic board, or a bad connection with the display port cable, and re-seating it could possibly help.

But from what I was able to gather from the official apple.com forum, is that many people have had this issue, some specifically say it would happen during cold weather.

No solutions found as far as a replaceable part that fails, they blame it on quality. I would take that with a grain of salt as someone might have the answer to the root cause of the horizontal lines issue on the 2016 retina 13” MBP.

Thanks alot for the response, can you share with me the links on apple forums that you went through. I'm contacting apple support too.

I've seen two with this problem and both needed new screens luckily they were under AppleCare+

Other than liquid or heat damage nothing you could have done would cause this. Basically it's a defective part from the get go.

Sorry for late reply Jason, here is the apple forum thread I had read through: https://discussions.apple.com/thread/783...

My MP 2017 is fixed by (unofficial) local store, they spend a lot of time to investigate, and they find out the root cause, I remember they said they just replaced a wire somewhere connect to monitor (hmm, I can’t remember exactly, but the point is “a wire cause this issue”). So I don’t have to replace any hardware else.



This is my screen before repair (horizontal line at the top edge and bottom edge):

Is it the same issue as the flexgate? Did they change the flex cable of the LCD?

Even though what we have is a different issue where we have black lines across the screen instead of the backlight being disabled in Flexgate.

https://ifixit.org/blog/13979/apples-201...

how much is the cost to replace the wire? i’m currently having the same problem. most people took their laptops to apple and they were told to replace the whole screen which gonna cost a fortune.

Hi Khang. Are you in HCMC? Did laptopvang solve that problem for you?

I am in HN and got the same problem but I don't know and where to fix it. Thank you.

cuong - Sorry to tell you this is not a wire issue its a de-lamination of the defuser and polarizer sheets from the backside of the display. The only way to fix this is to replace the full lid assembly.

Thanks Dan. How much do you have to pay for it? I am very upset now...

hey guys an update on my issue, i never went for a fix, the problem went away after i left it to rest for a few days, i believe its an overheat issue. my screen has been working fine for the past few months since reporting this. Not sure it will come back, but this is definitely a faulty hardware, and Apple is not admitting it!

Affected model: 2016 Macbook Pro touch bar

Thanks Jason, I believe you may be onto something there. If I shutdown my MacBook and don't use it for a couple of days when I first turn it on there are no lines either.

Unfortunately I use it for many hours most days so the issue has persisted, I also live in a relatively hot climate. The MacBook is often quite warm for the entire duration of its use.

It's a shame that they cannot seem to get adequate heat management on these MacBooks and they seem to have persistent design flaws in this current iteration, it is my first MacBook and probably my last due to this, despite how much I enjoy Mac OS.

Didn't touch my macbook over the weekend since this problem has been upsetting me lately. Lines are now taking much longer to appear and aren't as dark as they were before. From the beginning, leaving my computer to rest for a couple hours always made lines disappear for a while. Strangely, typing and touching the trackpad make them flicker. The angle of the screen does not seem to influence anything, at least in my case. Anyway, thanks for the update.

Please someone share actual solutions without Apple care services, as my MacBook is out of warranty. I’m having same issues from past 1 week.

I'm having the same issue too. After using my Macbook pro 2016 for awhile, the black horizontal lines will start to show up.

Also having the same issue. Is there an update on this? Started two days ago. I think I didn't help my case with the MacBook having a case. Turned it off for a couple of hours and it seemed to go well...Maybe I should leave it off a couple of days?

Well, strangely enough the lines on my macbook pro didn’t appear in the past few days, even with very heavy usage. The only thing different that I did that I can think of is that I built a new PC so the external monitor I used to plug to my macbook is now being used on the new machine. Thinking back, the problem may have first appeared when I started using an external monitor.

I live in Brazil and the cost of a new display assembly is R$3500,00 (~1000USD) according to Apple. I chose not to have the screen replaced as I’m not fully confident this is a display problem.

I have the same issue and I have narrowed it down to the dGPU. Every time the dGPU is active (external monitor, any app that uses dGPU), these lines appear.

If I remove the event causing dGPU use (disconnect monitor, exit apps using dGPU), the lines disappear quite quickly. I can reliably replicate this and monitor GPU usage in iStat menu.

Strangely, the external monitor itself doesn't show these lines, which is weird. I would have that a failing GPU would output glitches to all displays its driving.

Luckily, I have extended warranty and will take it to the Apple store for repairs.

Hello Gustavo,

I am also from Brazil and I am having the same issue with my MacBook Pro 2017 Touch Bar. Did you manage to fix the problem?

Regards.

Well, in my case the problem solved itself (knock on wood). It's been more than a month since the lines last appeared. The only thing different that I did was to ditch the external monitor. Nothing else. Let's see how long this lasts. Got a quote for R$3500 to replace the display in an authorised service provider, but wasn't entirely sure the display was to blame so I didn't go ahead with the repair.

Same. 4 months after the end of warranty. I contacted Apple Support to claim a warranty exception so they said this problem is not one which Apple will consider an exception. They also said in future Apple can consider a refund if they confirm the range of the problem, for now the only thing I can do is repairing for myself and spend a lot of money.

I’m having the same issue now on the bottom of my screen for 1 weeks in my macbook pro 13 inch 2017(tb) , and i’m out of warranty. If i use it without repairing it, will it damages more? because i don’t want to spend too much money on it. Should i go to unofficial store to repair it as apple stores cost more? I’m from India.

Recorded my display misbehaving today:

https://www.youtube.com/watch?v=p6FficHt...

At least in my case, these lines only appear after a while (~30 min or more). If I shutdown the computer and turn it back on right after, lines will still be there. However, if I wait a couple minutes before turning it back on, they won’t be there. The angle of the display doesn’t matter at all. Leaving the macbook on for long periods of time does make the problem worse. In this case, lines get darker and sometimes appear at the bottom as well. Ventilation seems to be working just fine and I can hear the fans kicking in during intensive tasks. Today when the lines appeared I placed my macbook in front of an AC unit and the lines faded slowly, so the problem is most likely heat related.

I had warranty left (since I bought my MBP 2016) from JBHifi Australia and proceeded to get it repaired when I had this problem. Took about 7 weeks to repair for me and luckily it was under warranty, otherwise the parts used totalled $523.75AUD. I’ve been using it again for another month now and these lines has began to appear again. So I honestly don’t know what to do, repair seems to do absolutely nothing and I’m too poor to either get a new MBP (for editing purposes) or get another repair.

Hi Guys,

If your macbook pro is the 13” 2016 touchbar model, you can take advantage of this:

https://www.apple.com/support/13-inch-ma...

Just tell Apple that you got an intermittent backlight issue and I got my screen replaced for free.

Tried that too, Apple Service Center didn't even considered this issue to be back light problem, and asked fo $600 for screen replacement.

How did you convince them that it is backlight problem??

No need to show any photo. Just tell them that it’s intermittent. They will do a serial number check and if it’s eligible they will take in for repair for free.

Happening on my MacBook 15” Retina mid 2016 and when i stopped using it for a few weeks when i went on vacation, when i returned the problem did not appear for a few days. Then it came back again after I used the computer heavily and has not stopped happening since. I think its related to thermals and appears when the computer runs hot.

I hope Apple acknowledges this problem and creates a service/recall or extended warranty program. They need to know that there are already a lot of units affected. This is also happing on my 2 friends MBPs - a Retina 13” and a 15”.

To make the issue happen? I think when the computer runs how by running a lot of apps or running heavy performing tasks

I think I found the cause, it’s a deformed display cable caused by heat.

This is a picture of the right display cable.

Here is another one, you can see a slight bump here.

And this is what it should look like normally, like the left display cable.

Unfortunately, it cannot be repaired manually, seeing it as a manufacturing defect, Apple should take action.

%#*@. Are you going to go to the Apple store? Please keep us updated. I will open mine soon. I am really hoping this is not the case for everyone with the problem. Thank you for keeping us posted on this. My laptop is out of warranty (2017 Macbook pro) and I replaced the display myself so I know they probably wont touch it...

Thankfully the lines don't always show up. Hopefully it does not get worse over time...

I'm not sure what I should be looking at. Can you point where is the deformation? And is it possible to change that part with an aftermarket part to fix the issue? Hopefully without having to replace the whole display assembly
