Led Lcd woes

So I've been working on a laptop this week that's been throwing me for a loop. This thing basically took a good fall and is now not showing anything on the screen. The screen its self looks to be in good condition. No cracks or damage what-so-ever. When I output to a desktop monitor via vga, it seems to do just fine, just no video (looking at it with a flashlight) or led's lighting up on the laptop screen.

I guess the thing that's throwing me is, I hooked up another LED LCD I had lying around to the laptop and I'm getting nothing from it either. I guess both could be dead, since they both came from busted laptops.

So my question is. What do you guys think the odds are that the LCD is dead?

I guess I'm just finding it hard to believe that a hard fall would kill the LCD, especially if its not been struck directly, and or having visible physical damage.

Thanks for any input.

Also, I reset the bios, booted to windows and tried toggling the laptop monitor on/off to no avail.
 
either take it apart to find the lose/broken connection and reconnect / resolder / replace it or have it repaired by a service technician.

obviously something did get damaged and fixing it will likely involve some disasembly and the fact that no overt physical signs of damage points to internal damage.

whether or not the entire screen is shot depends on what was damaged and since the screen looks ok might mean something in the display chain is broken now.

Long story short, open it yourself and fix or take it in for repair since until the damage is known the fix wont be known.

one more point is the bios still has a battery that would need to be removed to fully reset the board most times and that is internal not the normal battery so getting inside to see what is going on is pretty likely needed no matter what.
