My MacBook Pro has purple lines on the display screen
previously Brought this MacBook Pro 2019 version second hand a couple weeks ago. I have had no troubles at all until today. I have been using my laptop for work all morning and closed it. Once I reopened it again purples line starting coming on the screen and now there is permanently purple lines on the left hand side of my screen I will attach a photo. I have tried restarting it, shutting down but nothing has resolved this issue. Could I please have some help?
