I have an HP Pavilion G6. The screen (LED) doesn't work, but it displays fine on an external monitor with HDMI or VGA. The screen was obviously cracked so I got a new one. After replacing it, the screen was still black, so I replaced the monitor cable. Still nothing.
There's nothing at all on the screen, even when shining a light behind it. I'm assuming it can't be the GPU since it's displaying fine externally.
Any ideas what the problem could be?
