I got horizontal lines over the display! During the warranty period they replaced the board ( it blacked out ) and now this is happening. They refused to replace the device saying out of warranty and asked to replace it :-|. They were not even sure that changing the display will fix the issue. I am hesitant to replace the screen as I am better off to buy a new one rather keep repairing the faulty product.

Is there any way to fix it?

Tried
- Reinstall the OS
- External Display = Works fine
- Reseating those 3 cables

Lines kind of flickers, may be some lose cables?

Please help

It is not essential to get this fixed but I would like to if possible. I have tried the eraser method, the Vaseline method, and hand sanitizer. Any ideas?

Just wondering if anyone has been able to remove the cap covers on the hinge, and what the process was like?

Thank you,

Or not (as I suspect) as the aluminum chin and the whole glass and display are meld and integrated into one?

Thanks

I wonder if anyone can help me with an issue I am encountering following the installation of a new logic board. The original logic board had failed with no power to the iMac. I purchased a new sealed logic board from a third-party reseller and completed the insulation as per the self-repair instructions. When I turn the iMac on I am presented with the black screen showing an exclamation mark and the restore URL on it. When I try to restore the via usb-c and with my M2 MacBook Air and using DFU, I get the iMac to turn on and start the restore but after few minutes I get the following error messages;

The Mac "Mac" could not be restored. An unknown error occurred (53). 0634.0035

&

The System cannot be restored on this device.

The operation couldn't be completed.

(AMRestoreErrorDomain error 53 - Failed to handle message type StatusMsg (FDR failure)) [AMRestoreErrorDomain - 0x35

(53)]

Has anyone encountered this before or know the possible issue?

Thanks

This iMac M3 has not been turned on for probably a month, however the iMac is unable to turn on now. Between that month, there is a few days where my office had multiple rapid power surge/outages because of faulty breakers. The iMac has never been turned on in during those surges/outages, however the plug has never been disconnected from the wall.

While I have absolutely no knowledge of iMac troubleshooting, I have tried everything that forums have said (power cycle, safe mode, etc.) yet it still won't turn on at all. The power button still clicks fine, so I'm thinking that the power adapter that also houses the ethernet port is fried. Are there any other possibilities I should know of before telling my boss about the possible issues and fixes?

While perusing the several installation instructions, I might have a blade SSD on the control board (unconfirmed) that is part of the"Fusion" system

Will I be able to just replace the HDD with the SSD and format and install the OS as usual and not deal with the Blade SSD, or ????

Thanks in advance for any help,

Richard
