Hello, My macbook pro for some reason randomly developed vertical lines on the screen. However they aren’t persistent, rather they come and go? I didn’t spill any liquid but I cleaned my keyboard with alcohol and cotton swabs but i used very little liquid. Also the screen was fine for about an hour after i cleaned it. It started doing this as I was cleaning my hard disk and uninstalling applications. Any help would be appreciated! I also plugged it into my TV and it displayed just fine.
