Compaq Presario CQ56 Display Issues

I have a Compaq Presario CQ56 I've been working on. When I first got it, the screen would change colors and go all wacky when you moved it. I took it apart and dusted the connector for the screen.

Put it back together, screen worked on first boot, then nothing, but there was still an output on VGA, so I went to the recovery partition and re installed windows. Re install was complete, screen on laptop still didn't work. I restarted it after an update, and it worked for a second but then on the next boot, blank again with VGA out still working

Updated BIOS and display driver
Considering the screen was working fully, it's hard to think that this would be a hardware error. Any guesses?

I already checked the connecter, unplugged it and plugged it back in as well as dusted it off twice
