Horizontal lines on the screen are NEVER caused by a board.
Horizontal lines indicate a defective LCD panel (screen) no part except a NEW screen will fix it.
We recommend ordering by part number Always, never go off the back sticker,
remove the part from the TV and confirm all, all numbers MATCH perfect.
Often times there are TV models that usemore than one set of parts and/or panels.
Important Message: Part number can be found on the sticker of the board or part.
