I am Currently work on two dell computers that somehow have the same screen issue. On the first dell computer right when I turn the computer on I get no image only a grey screen with verticle lines. some of the lines are slightly colored. I replaced ram and hard drive and did not fix the problem. I also took the computer apart and checked the screen ribbons and all looks good. On the second computer the computer turns on fine I can see the back ground and use the computer however the screen slowly turns grey and the verticle lines show up. If I click the mouse or keyboard the screen comes back. and then over a 10 second time frame the screen starts to fade and gets the lines. As I was typing this the screen the Dell screen went grey and have pink and yellow verticle lines.
