I have a very odd display problem with my hp zd7000 laptop. For the last month or so whenever I go to turn it on I can hear it boot up into windows but no display. Usually if I turn the computer off and on a few times the display will fire up. Now not even that works. Heres what Ive found out so far: External monitor works checked all connections from display to main board (whenever I did get it to come on it would stay on even if I shook it, so I know nothings loose) When I have external monitor hooked up and use the key to switch to laptop display nothing happens, not even a backlight if I turn on computer with NO hard drive and do the same thing I get a backlight but nothing else checked the switch which turns off the display when you close the lid Anyone have any ideas? Could this be software related?
