Sharp LC-43LB371U disappearing lines - VIDEO	Can't Post

I have a Sharp LC-43LB371U, there are vertical lines that don’t go to the top over the menu. When I unplug the ribbon cable from the panel to the Tcon board and then plug it back in the lines are gone then come back after a few seconds. I’ve replaced Tcon board with no luck unless the new Tcon board I got was bad too?!?! I made a video to show what it does. Thanks I’m sdvance!!!!

This looks like a bad LCD panel or bad screen driver boards which also means bad panel. The screen driver boards are the boards the Tcon connects to, these boards are factory bonded to the LCD panel & often the bonding comes loose causing your issue.
