Persistent horizontal lines appear on iMac screen

Hey everyone! I have a great news.

Thanks to all of you and the thread creator for the evidence, and thanks to Apple for the integrity and standing behind their products.

I was able to get authorization for my case for repair as they are willing to honor it for repair beyond the warranty.

I am now able to go to the store and have it fixed without cost. Will confirm once it's done but I got verified by customer service that I can take it in.

Guys, as an update I was able to get Apple Support to grant me a free display replacement. I posted a full update on the interaction here: tiny.cc/5spyzz. It may be a strategy you can try on your own.

I don't want a new machine from Apple. I want to make sure my existing machine doesn't degrade further. Any advice is welcome. It may help M1 iMac users who haven't encountered this issue yet avoid it.

SAME problem here. In August (2024) the first lines appeared at the bottom of the display, increasing in November and in December becoming the same as yours. Sometimes they decrease, sometimes they blink a lot and the lateral (exactly at the height of your lines) gets extremely hot, even burning my finger superficially when touching it. Looking at an open screen you can see that this area is exactly a meeting point of two flexible power supply cables for the display. I strongly believe that their overheating is the cause of the problem.

I have already sent a lot of feedbacks, spoken to support and still have not had any satisfactory answer because it is no longer covered by the warranty, which is extremely disappointing and seems to me to be a manufacturing problem.

I have the same problem, M1 2021

Apple refused to replace..it’s definitely a manufacturing defect and they don’t seem to be releasing a service program! Given that we spend so much money on apple products they want half the value of the machine for a manufacturing defect! Disappointed!

I am having this same problem on my 2021, M1 iMac. The display is showing lines on the bottom half of the screen that look like interlacing lines. It started intermittently about a year ago and it would go away after a shut down, or restart. Current age of the iMac is about 4 years, with occasional use, about once a week.

I have also contacted them but they refused a replacement..They are asking me to pay for the display! Is there any communication that you have which will help me get a replacement!! I have told them about the threads and even media articles regarding this but they didn't care.

Spoke to a senior in Apple..but they outright refused a replacement. Called them twice about this but in vain...They said apple already has access to the support links and they will reimburse if they come up with a service program..but if I need to replace the display I have to pay INR 50,000! I'm so disappointed with the service!

I, like many others apparently, have the same issue with lines appearing on the screen. I took it in for diagnosis and it was determined that the problem was hardware related. The remedy is to replace the screen for a cost of about $700. I will probably buy a non-Apple monitor to hook up externally at a cost fair less than the repair.

Hi

i contacted Apple India 3-4 times for One time exception consideration, however, they are denying stating device is way out of warranty (3 yrs from date of purchase).

How to escalate to Apple USA?

pls explain

Hi,

I also Have same issue, contacted Apple India about same for 3-4 times over last 7 months but Apple is knowingly accepting that it’s on customer, Apple can provide repair at cost ~₹ 55000-60000 ($800-900 USD).

as per Apple support, They aren’t coming up any service program.

The advice I got from the Apple store in Leawood, Kansas is to buy a Mac Mini and new monitor. They said that the trade-in value for my computer is $0. Apparently, there haven't been enough reports of this problem for them to deem this a manufacturing flaw and offer a solution to its customers.

If there ever is a fix it will be announced here: Apple Service Programs - Apple Support

So make a bookmark of that site and check it frequently. Also anyone who has this problem and has not taken it into an Apple Genius bar should so they know the extent of the problem.

So I took the computer to the local Apple Service provider and they are charging $921 USD... yes.. NINE HUNDRED AND TWENTY ONE... basically more than a new imac mini.. So i just called Apple Support.. and same story.. you have to pay for the new display... THIS IS BAD, this when this thing pops up it's going to be a mess for them.. this is clearly a design problem that they did and we have to pay for. DO NOT buy an iMac until they assure they are going to fix this issue, your mac could fail at any time and there is no waranty that even if you fix it, it wont happen again. My guess is that Apple is not talking about it becase there are too many iMacs around, and it will be impossible for them to recall or to do free repais. This is bad, very bad.. it really makes me thing about investing my money in Apple products if they are not responsable for their mistakes.

Black lines have appeared at the bottom of my 2021 M1 Mac screen. I’ve read reports that these lines tend to increase over time. The device is still usable, but I’m concerned as it is already affecting my experience. I need a solution — it can’t be that a device like this lasts only four years.
