Dell Inspiron 9300 Dim LCD Screen in User to User Help Posted July 30, 2007 · Edited July 30, 2007 by gordesky1 should be 2 plugs one go in the video card than another one plugs in the inverter thats located on the bottom when you open it up were it says dell on the bottom of the screen breeze. i whould check the inverter wires and see if they plug in or something. wait there is ony 1 wire and that plugs in the video card. but there should be 2 wires on the inverter like the screen goes to the inverter than on the other end of the inverter there another wire and that goes to the video. i whould check those wires maybee they loose. and there should be one on the back of the screen also for the video. if they they good the ony things i whould say is the inverter is bad or going out or the video card is on its way out but i lean more to the inverter than the video card.
