As long as there is no sign of damage, but let's let LG's techs determine what needs fixing. If you got it at CostCo, just go back and get another.

Hi I mounted my LG55la860w onto a wall bracket. But once I turned it back on there is a white line an inch thick running down far right hand side with coloured bits mixed in. It must of been due to the handling of TV putting up on bracket as it wasn't there before when it was on stand. I was trying to be as careful as I could. Can this be easily fixed or is it there to stay? TV is a few months old and cost over £1000.
