The problem is not the screen but the inverter board inside the laptop, it supplies high voltage to the internal fluorescent (cold cathode) bulbs that back light the display. Lots of these available on ebay and they plug right in, no soldering is necessary. I cant imagine both screens had bad cold cathode lamps. Generic answer to all dark screens on laptops
