Persistent horizontal lines appear on iMac screen

I am reaching out to share an ongoing issue I, along with several other users, have been experiencing with our iMac 24-inch models, and to seek a collective resolution.


Problem Description:

  • Persistent horizontal lines appear on the screen, which significantly hampers the usability and visual appeal of the device.
  • This problem arises without any physical damage, and despite the stationary nature of the device.


Steps Taken:

  • Connected to an external display: The external display works fine, indicating the issue is with the iMac's internal display.
  • Reinstalled the OS: The problem persisted post reinstallation.
  • Avoided operating the iMac for a week: No change in the situation.


Concerns:

  • The cost of screen replacement is high, and there's no assurance that it will resolve the issue permanently.
  • The quality concern is alarming especially for a brand that positions itself as a premium segment player.
  • The support received thus far has been unsatisfactory, with no definitive solutions provided apart from a costly screen replacement suggestion.





Please do not ask us to visit to service center and replace the screen for 650USD + , problem happens mostly after warranty.

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

I have the same problem.

iMac 24" 2021 was bought in Aug 2021. Now with just two and a half years.

Lines started to appear near the bottom of the screen and went up until fill up about 70% of the screen with ghosts of the dock app icons at the bottom.

My second monitor is working perfectly.

Very strange...

I had purchased my iMac M1 in July 2021... And today, 7th April 2024, I was surprised to see this lines on the screen... Even more surprised to see so many folks have got affected with same issues... in hardly 2 years of usage.


So much for the Apple Long lasting durable product ... can be thrown out of the window. Spending so much amount for display replacement can be equal to buying a new PC/Mac itself...


All the more ridiculous now to spend more money on buying an external monitor in hardly 2-3 years to continue using existing bad-screen iMac or end up buying a new one altogether :(


And since it's not in warranty.... Apple will care a **** to have this rectified / resolved / addressed !!


If anyone has found any way forward with software update or any other way to resolve this issue, pls let me know !!
