Everything was working fine until one day i turned on the Mac and vertical coloured lines appear on the display.
Nothing change no matter the angle of the display.

As a sanity check, you should plug in an external monitor. That will let you verify that it's a screen issue and not a GPU problem. Let us know what you see.
