Dell V131 won't power on while the internal screen is attached.

Hey,

My Dell V131 won't power on while the internal LCD is attached to the MB. It works fine when I plug in my external monitor and detach the LCD. As soon as I plug in the LCD charger's led turns off. It  still beeps and indicates that there is a problem with the screen when powering on using the external screen.

I've tried swapping out the screen, unplugged all unnecessary components, used another charger, all that regular stuff.

Regards.
