Horizontal lines over iMac 24 screen
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?
- Reinstall the OS
- External Display = Works fine
- Reseating those 3 cables
Lines kind of flickers, may be some lose cables?
