ANSWERS:

@amammoth this does not look like a tab error at all. This does look like a a bad X-board or a bad IC on the flex to the panel. Check the ribo cables going to the panel in the area where that line appears. Make sure that it is inserted okay and the it is not damaged. You will have to remove the back of your TV and check for damaged components on your board.
