this does look like a bad panel but you do have to check your boards as well. I do not think this is a TAB error since the lines would look different. It could be gate driver issues on the LCD driver board (part of the panel). Remove the back of your TV and check the boards and the wiring. Post some images of this with your question. That way we can see what you see. Use this guide [guide|21499].
