So One Day I was using my macbook and suddenly my screen showing lines. So I’m Wondering if its flex gate issue or it’s in the panel.
That appears to be a hardware issue with the built-in Display Assembly. Have Apple or an Apple Authorized Service Provider confirm and provide you with a repair estimate.
be sure you have a DEFINITE way to reproduce the problem, the genus bar guys do not just take your word for it, they want the ability to see it happening.
next, restart in safe mode, where almost no add-ons are loaded, and reproduce the problem there to demonstrate it is not caused by something you added.
after a shutdown and restart, does the screen go back to normal?
it could be a one-off issue.
Yes, For some minutes the screen works good after restart.
