Macbookpro2013 screen has lines flickering all over it

Hi,

I think it's a hardware related issue, so you should contact Apple support to tell them about the circumstance you face with now.

Or if your neighborhood retail Apple Store is open, try to make Genius Bar reservation or take your MacBook Pro to your neighborhood Apple Authorized Service Provider if it is open to be examined it.
