If you ran safe mode and it still appeared the same I would believe it's safe to say it's the LCD that's damaged.

You can also check the cable and see if you just need to reseat it, possibly loose. [https://www.youtube.com/watch?v=4-Ca9C8QCS8|Video guide.]

I would also recommend you back up your data on smart switch, just in case the screen eventually goes out.

Good Luck
