Persistent horizontal lines appear on iMac screen

It's a costly fix for a problem that only occurred due to a faulty bit of design/engineering from Apple.

Even if we did do the display replacement it won't be a permanent fix as the same problem will come back eventually. It happened to me.

And since the iMac is somewhat of a niche product Apple will employ it's tried and tested formula; Ignore the complaints until we go away. Eventually Apple may even offer an 'acknowledgement' of this issue but it will count jack-squat for those of us affected.

And as for long time iMac users like myself, I will have to think long and hard before purchasing another iMac (which I prob won't) or even purchasing another Apple product.

yes, i would of wanted to do this, however the upper right hand part of the imac gets extremely hot while its on. dont want to take the chance of it catching on fire while not being used.

Anyone experiencing the same thing?

Mine does the same thing. I told them I was concerned it had the potential to be a safety concern and they escalated as such but it was a no go. I burnt my hand on it. They literally told me if it did happen to catch something on fire they would not be liable. Absolutely ridiculous.

much more serious than ridiculous -- i hope you got their employee info -- confirm that advice is quoted in your case notes -- you got a case number (i hope) -- i would call again tomorrow, reference your case number, insist that your notes are up to date (have them read them back to you) -- that call should be logged in any case -- get a screenshot off your Recent Calls to document...

it seems reasonable that you speak to a supervisor over that advice -- i would -- get a confirmed case number and accurate case notes logged -- good luck

The same thing happened to my iMac M1 (A2438) a few days ago. The screen has horizontal lines.

It's out of warranty, so Apple asked me to come and have the repair done (about €700) at my own expense.

Thanks Apple

we have same issue with our M1 IMac 2021, persistent horizontal lines and smoke with burn smell. Apple India denied exception for repair charges and says it’s a paid service. we are unable to use the device now. It’s upgraded one. 16/512. please let me know how to escalate to Apple USA directly. we are in Hyderabad, India. any help would be appreciated.

To Universall ,

we also have same issue with our IMac like yours. we contacted Apple support through chat with USA country in Apple account. but they assigned to India support team. Apple India denied exception and said it would be paid service. please let me know how to directly escalate to USA support. any help would be appreciated. thank you.

The longer Apple waits to address this unfortunate issue, the more once loyal customers will find a solution on their own. Perhaps by buying another iMac and taking their chances it won't recur, perhaps by paying out of pocket to replace the screen assembly (and hope the issue won't recur), by moving to a Mac Mini or back to a PC with an avoidably bad experience under their belts and with a justifiable grudge against a multi-trillion dollar company that it appears has let everybody down.

Which are you / which will you be?

Immediately after the screen fault disaster I purchased a Mini and a very good monitor in order to keep on working.

For a long time I stood waiting hoping Apple would have fixed my M1 iMac screen for free, but it seems they are deaf.

I sold my Macbook as soon as I realize what "they" have become and I went for a Dell 5420 notebook (i5 refurbished 250 Euros) with Debian.

As soon as I'll complete some tasks here I'll roll back to Linux, only iPhone will represent an apple for future here.

It seems that the issue is downplayed with search result manipulation. May be it is just me, but I am not able to access this thread or any related ones with keyword search such as "iMac horizontal lines".

Experienced the same issue for a 2021 M1 iMac, went to the Apple Store for checking and was quoted a service charge since it's out of warranty. I was told that since it's not on the official recall program, the staff are not able to offer any better options at the moment. I will try to find some senior specialist to see what are the other options.

?

It is literally the first search result from Brave, and the second one from DDG.

I'm sorry, I feel your frustration. Of course, what I described is just a workaround, because when lines appear the screen is definetly damaged and you will never be able to run it like brand new again. No more full light. But I think it helps to prevent even more damage to the screen while we are waiting for Apple to be nice and cool to us. I heard that some people got their screen fixed for free.

Is that a must to download use that what TPro Fan control? I do check some users feedback etc. Is more for " technical expert folks " in the sense. A lot claim just temp monitor. The fans will auto switch to default override the software. So you just only try and so far no lines reappear? I think so. As I have mention , I never do anything and happen the lines gone. I don't know. I use as per normal. I never use new software or even play games. I only just surf net , watch youtube videos, and do simple work. When the lines suddenly appear on Oct last year. Daily I using it even now , despite the lines appear at the bottom and flicker. Just that as I have mention suddenly last year Nov the lines gone. Dec whole month never appear. Now Jan suddenly lines are back.

About the replacement screen also just " temp solution " After using one year or so. The lines will appear. A lot already mention is a " Design flaws " according from one Tech used to work in Apple or whatever.

I feel those managed to replace free will not use it, More like trade in or sell to others. I don't know. I just continue using it since the line haven't cover the entire screen. Only still at the bottom but I do see few new lines appear.

Next are you using the latest Mac OSX? If You can make the lines don't appear anymore by " Software ways " indirectly means Mac OSX updates got some stuffs trigger to make the voltage higher near the screen. but the tech mention is a design flaws by Apple come the cable to the screen.

Nevertheless. Obviously this thread will be longer and longer as I expect More M series users going to discover and noticed every M series user encounter this lines issues. Some claim so far use for 3 years no lines. They claim maybe we get " bad batches " I also don't know....

Sorry for My bad Written English. I fee kinda **** off whenever come back here yet Apple never mention anything on us as users concern...

The same happened to my iMac M1. The lines appeared the 1st December and after 10 days they suddenly disappeared. I almost couldn't believe my eyes! The display was perfect again! Unfortunately it only lasted normal a week because the flickering lines are back again!!!
