Horizontal lines are caused by a bad screen. NO BOARD will fix horizontal lines. We are here to help! NOTE LG & Vizio TVs must be plugged in for 5 minutes before it will turn on. For main board replacements check for possible firmware upgrades. Inspect ALL Ribbons and connectors. Any tears or bad connections between boards must be replaced FIRST.
