Is there a fix for this display problem: vertical lines?

@herojig that looks like a TAB error. The thin ribbon cables that enter the LCD panel from the LCD driver board have somehow lost contact. Those are bonded in a special manner. You can try and exert some pressure on the ribbon that enters the panel where those lines are and see if that removes/changes those to verify. If so, you can try to use some good adhesive tape and tape them down with some tension. If it works it is only a temporary fix. A permanent fix would be a replacement screen or having your send off for repair (not cheap at all)
