Screen has vertical white lines

I kept my samsung cell phone leaning against my Mac Book Pro while working on the Mac. When I removed the phone white lines have appeared about 1.5 inches thick extreme right top to bottom. What should I do kindly help. Thank you.

Without being able to see the lines you may have a defective Display that needs repaired, but first try rebooting the laptop and try booting into Safe Mode. Try running the Apple Diagnostics. If you see the lines on the screen when running the diagnostics, then you have a hardware issue with the display.
