The lines could not be removed. The TV was returned to Wal-Mart easily. However while waiting in line to make return I met a woman who had the same experience with the TV. I would not recommend the TV and the TV was echanged for a Vizio TV. Samsung 32" Class (31.5" Diag.) LCD 403 Series TV (LN32D403E2DXZA) review by Bryanmatt can be read at Walmart
