Laptop white screen on power-up. Still displays via HDMI output

my wife's laptop recently started displaying a white screen. It doesn't show post or anything, just a white screen when it's powered on. However, it works normally with HDMI output to our television.
I took it apart and fiddled with both ends of the display cable, but I either didn't fiddle correctly or that's just not the problem. I also noticed that the screen won't turn off anymore when the laptop is closed. Is there a name for the mechanism that controls this function, so I can try and locate it?
My guesses are that the problem lies with the screen itself or the display cable, but I'm curious if there's anything else I might be overlooking. Also of note is that the left hinge is partially broken. The corner of the plastic computer case broke off, so the hinge is exposed and doesn't stay in place. I've tried holding it in place, wiggling it around, tapping various parts of the computer, but the white screen remains.

I have a laptop with a busted screen, so I am going to install a replacement. Does the replacement screen have to be the same resolution as the original?

It can be a different resolution as long as the laptop supports the display panel you are replacing the original display with.
For example a Dell Latitude D630 supports two displays, WXGA+ and WXGA. You should be able to swap up or down, but be sure that you get an inverter with the new display.

Worse, it has to be the same model number for a Dell. Sometimes the same model number is not the same panel it seems. Check to ensure the replacement screen has the inverter attached or the inverter holder attached to the screen - some don't- and the Dell d630 needs the inverter attached to the bottom of the panel.
