Persistent horizontal lines appear on iMac screen

Last year, my monitor is having the horizontal lines about 1/4 from the bottom. Just yesterday, the horizontal lines is between 1/2 to 2/3 of the screen. Not usable anymore unless using another attached monitor.

When will APPLE act and help us on these?

Dear Jotap62,

"The (very expensive) out-of-warranty repair has always been paid for by users (those who choose to fix it)."

Agree! We will want to fix the problem. Since most devices are out of warranty, one must pay for the repair or replacement. That's a valid point!

However, buyers who have paid for their devices need some response from Apple. I am sure no apology, acceptance or roll-back may come from their side! Nevertheless, a simple reaction like 'we made a mistake' will do. This or that way, every buyer wants to move on rather than staring at the faulty screen dancing and flaunting the 'careless' moves of Apple, the company that somehow manages to have many screens worldwide failing to the same issue! That is why this visible anger is appearing here.

An update:

From what I can observe, the lines do not only flicker. Right at the top, where the lines begin, there are reflections of what's on the display below. I am attaching a few screenshots that experts can observe. Also, if hardware experts are monitoring this discussion, do hardware problems look like these? Something on your screen finding reflection on a different part of it?

hello!

i have exactly the same issue since yesterday, I bought my imac (24 inch, M1, 2021) on 5March 2022 and yesterday I experienced these color lines while I left my computer on for awhile… I just bought it for less than 3 years??? and I am still covered under warranty, I am afraid that after repair the same issue is going to come back up again….

If this happened to me if I had an iMac M1, I would be extremely angry about this call. Saying to someone we would have replaced it for Free if you kept it, instead of either repairing or selling it for another one is a slap in the face.

Hi Newcompguy12,

Thank you for sharing the update!

Did you mean Apple might start providing free replacement for iMac screen? I'm still holding my iMac (which got the flickering black lines in May this year; I'm not using iMac at the moment, just let it there). If so, how should I ask for it to the Genius Bar staff?

Thanks!

Sameeee... After almost a year of reporting it, I recently got a call too, but the CS didn't offer me a replacement. lol maybe because the line on my computer is not grave enough to warrant a replacement, mine was just one line on the side, but still. their product is faulty.

I don't know what they will do. I was promised someone higher up the chain would call and or email me to see what they could do. We'll see. I have no idea if the "we would have replaced it" is just something this one person thinks or if it is official policy. I'm expecting that I won't be compensated in any way but if you still have your imac maybe you could get a free replacement. All I know is that I was contacted via email and phone by AppleCare Outreach. I checked the number, and the email address to make sure those were real, and the links did take me directly to Apple log in.

Oh, and if you're asking if they'll replace the display or the whole computer, I don't know.

Hello, I Had Been Using This IMac Since 2021, But There is A Screen Issue Which Was Arises Last Year. This problem Occurred without any physical damage, There Been A permanent Black lines Which was very annoying, Me and Many User Facing This Same Problem. I request Apple Team To Resolve This Problem

I have M3, 24gb RAM 4 ports. I keep my iMac always on, just sleep when not in use. I've been using it today for at least 3 hours straight. Temperature on that spot is 83 degrees. Top left is 83, top middle is 87, top right is 86, right middle is 83, bottom right 81, bottom left 81, middle 94. I'm Processing a large image with Topaz Ai and the fans are running fast since it's processor intensive. These are temperatures. When idle is much cooler. So based on your image, I don't know if you took the temperature on that spot, something is clearly wrong to go so hot that it's causing it to discolor there. Thats not good at all.

I too have the same issue, Apple should recognize this defect and sort out this issue free of cost for all those affected. I am very unhappy with this situation, the screen replacement cost is pretty high. :(

I too now have this problem. I have a 2 port iMac 24" 2021. The lines are starting at the bottom on the right side and stopping about 4/5 of the way up my screen and 2/3 of the way to the left. This is crazy, has anyone gotten apple to repair this even though we are out of the support period?

Hi everyone,

I'm reaching out because I'm having the same frustrating issue with my iMac 24" M1 bought in October 2021. After just three years of careful use, the screen started displaying horizontal lines that flicker and make it difficult to use.

I'm really disappointed to see this happen to such a recent and expensive device. I've tried troubleshooting steps, but nothing seems to work.

Any updates on this issue? If so, how did you resolve it? Any advice or suggestions would be greatly appreciated.

Thanks in advance for your help!

Thanks for letting us know your situation, I too contacted Apple support but they denied free replacement so I paid the full cost for the screen replacement 15 days ago, can someone advise if I can request a refund? I will try to raise a refund request through chat support soon...

Apple also offered me a free replacement recently, but the process has not been finalised (my iMac was captured, meaning it was collected by Apple; now I'm waiting for the replacement). My story is similar to the ones have appeared in this thread. I'll share details once receiving the replacement (just wanna provide a little encouragement to this thread as early as possible, following Michael).
