Well, you have tested the obvious, connectors and backlight. You have 3 components on the TV, not counting the speakers. You have replaced 2 of them.

Well, you have tested the obvious, connectors and backlight. However, the backlight wouldn't cause lines on the screen. You have 3 components on the TV, not counting the speakers. You have replaced 2 of them.
Assuming the replacement parts are fully functional, there is not much left but the panel.
