TV Part Types: Main Board. ALL PARTS WERE REMOVED FROM A WORKING, TESTED TV WITH A CRACKED SCREEN. SOME WERE STILL NEW IN THERE ORIGINAL BOX AND SOME WERE NOT. 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.
