Macbook pro screen white lines

[ahmedessamedeen]

Hi everyone, I have a macbook pro 2015 15" core i7 with 2 graphic cards (2 GB AMD Radeon R9 M370X, 1.5 GB Intel Iris Pr) it was working fine at night, but when I tried to open it at morning it was displaying the following screen in picture :

the whole screen display these lines but a part of the top bar the time and battery status
when I tried to connect it to an external display it worked fine.

the screen isn't broken and has no cracks of scratches

Does anyone have a previous experience with a problem like this.

I have an issue with my mac book pro A1502 which shows in the picture below two vertical lines starting yesterday after replacing the WiFi card. when I tried to connect it to an external display it worked fine. Is anyone can say how to fix this problem?

May be a cable issue. They're fragile. If no one here gives more info, try posting at ifixit where they specialize in such things.
