Toshiba Laptop Black Screen

I have a Toshiba Laptop, Was reinstalling windows 7 on it last night left it doing the updates then shut it down. Turned it on this this afternoon only to find the laptop screen is Black and also there is a burning smell coming from the Fan.

I connected the Laptop to a external monitor that is fine, Can go into bios, Windows boots up fine Etc.
Just took apart the laptop earlier to check all the cables where in correctly, Checked the motherboard over for any damage, burnt bits but but found nothing. Just put it back together now but im still getting this burning smell and i still cant use the laptop screen only a external screen.

I Tried Pressing FN+F5 to switch to the laptop screen, But still black screen. Any Suggestions please ?

Thanks

Question: Any suggestions how I can get my boot from my usb key on my toshiba?

PC:toshiba satellite p850-00e
USB:San disk 128 gb
Brand new solid state: King Dian 128 GB solid state

Description:
Attempting to install windows 10 on a Toshiba satellite p850-00e with a new solid state drive I just put in.

I press F12 loading, i get the boot menu. I select usb and I just get a black screen. No prompt to windows 10.

I tried the same usb on my desktop to boot from and it worked

1. boot menu option to be CSM.
   
2. boot priority to be top priority. Made no difference.
   
3. Boot speed is normal.
   
4. Boot security is disabled
   

 

How to get into safe mode on Toshiba satellite

Windows 10 does not load on startup, no Toshiba logo, just a looping black screen/blue screen with cursor. And the bios is on slow boot.
