Persistent horizontal lines appear on iMac screen

I just received my repaired Imac. every thing looks beautiful and it is just like new! It only took 3 days total to fix and I paid zero :)

I am very thankful.

Overal process:

1. Kept apple in good consciousness and practiced released judgment and frustration and remained in forgiveness and non-attached frequency. 2 Reached to chat support and requested senior advisor 3. Had a genuine conversion about my appreciation for apple and how there is a case of manufacturing that can be happy to any company and requested for them to investigate this thread - as it is well documented. (Thanks to all of you) 4. She forwarded it to engineers and requested the photos and files from me, and within a few days had been approved for repair.

I trust this can be done for all the other people with the same issue and hopefully in the future if it happened again they can upgrade us to a newer model. May be we can all get an M3 ? :P

Talk soon!

Hi everyone. Please be sure to report this issue directly to Apple via the Support Chat at https://getsupport.apple.com/solutions. They now have an Apple internal tracking number to capture reports specifically for this display issue on the 2021 iMac. If all goes well, this is a pre-cursor to an official out of warranty free repair program.

I learned about this while at the Genius bar with my 2021 iMac. The tech showed me the info on his support device that this issue is being tracked under an official Apple support issue number. It was like EF something. Anyway, DEFINITELY REPORT THIS ISSUE DIRECTLY TO APPLE SUPPORT!

as an apply fanboy, im shocked at their response to this.

first apple product to fail on me, and judging from how fast it went, not the last sadly

It was purchased in Japan around 2022. I have been experiencing similar symptoms since the night before last.

I contacted support based on this thread and was given the opportunity to speak with a specialist.

We are waiting for a response as to what action will be taken at this time.

If it is a product problem, I am sure that similar symptoms will appear again in a few years when I repair it at actual cost...

I feel that this is a trust issue for Apple products.

This is just the beginning. My iMac M1 started with some lines below, slowly filled up over the span of few months and eventually a black screen. If the problem is the quality of the product, a replacement will give you the problem again. Why are we bearing the cost of a product that is below par?

Revised version of post removed by the moderators.

Update: I decided not to replace the display for $648.00 as I felt the imac might have other problems if this happened after only 30 months. I got an estimate of $105.00 on the Apple trade in page I paid about $1500.00 for. The questionnaire specifically asks if the monitor is fully functional, to which I answered no. That knocked the trade in value way down, to that $105.00 number.

I sent in the imac using the kit they sent. About a week later got an email notification that they revised my trade in amount to $0.00. The reason given was that the display was not fully functional, which is why I was trading it in the first place.

I never mishandled the mac, it is surge protected, and I've never broken a computer I own. My last imac lasted 7 years and I only replaced it for compatibility issues with new software/apps and internet compatibility.

I'll reattach the image of the imac I traded in for zero dollars here. Not only were there lines as you see, but they flashed like a strobe. And yes, I took it in to the genius bar where they said it was the display and the only options were using an external monitor or getting a new display for it at $648.00.

I just want to restate I was not satisfied with this experience.

I've been to the Apple Store in Shanghai and the repair fee without Apple Care is about RMB 4,891 which is even more than the recycle fee lol. They said that the solution could only be screen replacement and they have no idea why the problem came out. Cuz there are so many user suffering the same problem I wonder if Apple should be responsible for this problem.

I was quoted around $700-800 at apple store MBS. I spoke to a third party vendor. He told me the problem lies with the monitors, probably defective. My screen has completely blackened out and I am relying on an external monitor to do my work. It has got nothing to do with software. low quality monitor issue

Is Apple not aware of this issue or just trying to ignore? I am also located in Singapore, went to Apple Service Center last Sept 2023 and was quoted of SGD900++ to fix the issue. Very expensive and this is not caused randomly by any mishandling, this is really an issue on Apple's hardware and design of this iMac model.

I did not proceed to have it fixed, I just bought a second hand monitor and attached to this iMac for just $100.

But then again, Apple should not ignore this. How we can make this a trending topic in Social Media? Once this trends, I am sure Apple will do something as that will affect their future sales.

Any suggestion to make this trending? Maybe we can post a video in Youtube and TikTok?

In case Apple Requires proof of my case you can look up Case number 10********92. They can look this up from their back end and get clarity.

This should be very clearly proven so we can ALL get this resolved forever! :)

I had the same issue with my iMac 24" M1 2021 after using it for 2.5 years.

After reading all the threads related to this issue, I've contacted Apple chat support and tried to negotiate a free repair for this widespread issue.

Apple chat support said that they don't have the authority to do this and ask me to contact phone support. Phone support said the same thing and asked me to take the iMac and go to Apple store. And Apple Store support said they can't do anything unless the issue appears in this Apple Service Programs list, and he suggested me to leave a message in Apple Feedback.

What happened next was that the rim became super hot when the iMac was switched on even though I've already turned the brightness of the screen to the lowest. There's a burn mark at the rim on the left-hand side and I believe there's a short circuit inside.

The screen blacked out after 3 weeks and it is now completely dead.

Nearly a year after reporting this problem to Apple I got a call today from someone about this issue. They knew the date I took in my computer to be assessed and knew about this forum which is where they get a lot of their info. The call was from an official Mac number, I checked.

Anyway it just made everything way worse. We went through the problem, what I did, what the Apple store told me, how much it was going to cost for a new display and why I decided just to get a new Imac. We also went through how the official Apple site tell you to send in your "old" Mac for credit toward your new one and how when I did that they adjusted my credit/refund down to zero because of some alleged smudges on the display.

So the caller had asked me if I still had the computer and told me if I did they could have replaced it for free.

So if I had held on to the defective item for a year, not chosen to get the credit for it which they denied anyway, I could have got a free replacement, which seems to be them acknowledging responsibility on some level.

But no, this call just served to tell me not only did they sell me a bad product, then deny the credit they indicated was due, but now are taunting me with "you could have had a new one for free." Ha ha. Wow.

To be clear, the caller was very nice and helpful and was doing her job trying to gather info, but I don't get why Apple would run things this way.

@jot hey - here is how:

1. I used the normal support channels, to speak to the support through chat
2. In the chat conversions, I requested to be transferred to a senior representative regarding a special situation that I need the highest level to be able to help me.
3. I was then scheduled a call with a "senior representative who I Katherine"

Key points:

1. I kept doing forgiveness work, releasing apple and the situation and I became willing to let it go if they are not willing - so I wasn't coming from an angry voice tone, but from a calm, and genuine voice tone of wanting to fix this together
2. I made sure I am being calm and I expressed gratitude to apple and told her how I spent over 7K in the past year alone,
3. She already had seen this thread and she knew and agreed something is not right.

Realizing Apple is a multi-billion dollar company and they really do stand behind their product, now there is enough evidence here for them to help those of us in need.

I am now communicating with a senior advisor from Apple (Katerine) she sounds very professional and empathic and she acknowledges that something strange is taking place with so many cases.

I am forwarding the pictures and data to file a case and trusting the engineers who will review the case will take responsibility and hopefully this will be resolved not just for me but for all of us, please keep all your evidence posted here so they can see the pictures.

unfortunately I'm having the same problem. Such a beautiful product at such a high price (at least in Brazil). Apple. please: let's recognize serial failure and provide the usual good customer service. thanks.
