I posted a few weeks ago concerning a Dell XPS 1640 laptop I have. I replaced the RAM. Upgraded from 4G to 8G. After replacing the RAM the display would not work. I put the old ram back in and the display STILL wouldnt work. I hooked up an external display and ran F12 diagnostics. EVERYTHING passed. No RAM problems, No display problems. Inverter checked out, etc.
After the disgnostics test I tried to let it boot up but it wouldn't. I got a screen that was one color with a lighter color "trim" around it.
I know I bought the correct ram and have tried taking it out and replacing it hundreds of times to make sure it was in correctly. I don't know what to do next. Does anyone have any suggestions?
If it worked fine before opening up the case, are you sure that an LCD cable is not loose, pinched, damaged, etc.?
Yes, it worked fine before. That's why I am so confused. I have looked at would be involved to get to the LCD cable and I would have to take the whole laptop apart, almost, so I can't believe it might be THAT.
I really don't want to take the whole thing apart, and, anyway, how could a cable get pinched so easily if it so hard to get to? Please help me understand!
