I have a dell inspiron 1720 hooked up to a acer external monitor. When I first hooked up the laptop to the display it worked fine. No problems. I have a nvidia gefore 8600 gt card and I have updated the driver to the windows 7 driver. Well all of a sudden my laptop display stopped coming on. On my laptop the screen is black and you can see a very very faint picture on it. I tried unplugging the external monitor and it didin't work. I unplugged the power and the battery and restarted numerous times. A couple of times I got the dell loading screen to come up but then it went back to the black faint screen. One time I got the windows 7 booting up screen to show but again went to the faint black screen a few seconds later. Its not the brightness turned down either because the screen is totally black and you can barley make out a faint picture of my desktop on it. Only if you look at it a certain way when the light hits it. Any help would be appreciated.
