Let the computer boot all the way and take a flashlight and shine it up close to the screen and see if you get any image at all no matter how faint then your backlight is out. If you get no image at all then it could be inverter or cable issue.

EDIT: Just to make sure we've covered all our bases. Have you tried using the external monitor to be sure somehow the desktop wasnt extended and set to only show up on the external and not the main screen?

Once the VGA cable removed, shouldn't the display automatically switch back?

On most laptops (not all) the function + F4 button will swap the video modes. It's a three toggle switch.

In mode 1 the display is only on the LCD
In mode 2 the display is on both the LCD & the 2nd VGA port
In mode 3 the display is on just the 2nd VGA port

It doesn't switch between the two by cable attachment.

Usally On laptops, when the screen goes ALL WHITE it's a sign that the video cable is bad or has been disconnected.
