We turned it on one day and now it has lines. I pulled the back off and cleaned the ribbon connections with rubbing alcohol and they are still there. Any ideas whats next?
Its a UN46B6000VFXZA.

For TVs it's often much easier and often cheaper to just replace it. You'd have to try different system board, maybe a different screen. You can buy lots of used newer working TVs in that size or larger for about $200, sometimes less.
