If the procedure you were advised to try didn’t work then you almost certainly have a hardware issue that needs to be examined and diagnosed by a service technician. There is likely nothing you can do to fix this and you should take your Mac to an Apple Store or authorized service provider for diagnosis and repair. If you purchased AppleCare when you bought your Mac it may still be under that extended warranty.

Hello mingoslkd,


I have tried that method and it did not resolve the problem.


The lines sometimes disappear when I change the angle of the screen. But doesn't work always and it does not work in the angle I want it to. Now the screen has also started to flicker with the lines. Please help me with this issue as this is the only computer that I have to work.


Thank you
