Does the TV have a grounded 3 prong plug?
lift the ground pin with one of those hardware store grounding adapters. (3 to 2 pin power plug adapter)
Do the lines go away?
Disconnect the inputs to the TV , leave just one input connected. Do the lines go away?
any time you have more than one ground connected to the TV, you can get lines. It's called a ground loop.

The TV cord does not have a ground prong nor does it remove from back of TV like my 42" Samsung

unfortunately, if there is only one device plugged in and the lines are still there, the horizontal amplifier has gone sour. You will need to get the unit serviced at a repair center.

Thank you, but why would it be a horizontal amp if the lines are vertical?

the lines appear when the picture cannot function horizontally
