White Line after replacing battery

Replaced my battery recently and cannot get this white line on the screen to go away. Got the new battery installed, tested it, and everything worked fine. Disconnected and installed the new water seal, then got it put back together and now have a vertical white line through the screen. I have unplugged and replugged in every cable always disconnecting the battery first but to no help. Still a white line in the same exact spot. Everything else works just fine like touch ect. I even tried cleaning all connections with some alcohol but that didnt help either.
