Laptop won't start after screen issue

I was using my laptop yesterday afternoon, when the screen began to fail. I turned the laptop off because it had froze, and when I tried to turn it back on, it just continuously reboots and shuts off, and the screen will not come on.

I have tried plugging in an external screen, but it does not receive a signal from the laptop, nor will the external keyboard I have to use (laptop keyboard is broken, not important).

Is there any way I can get the laptop to work again without taking it to a repair shop, or does a certain part need to be replaced?
 
It could be one of several issues and from the sounds of it, would require a part replacement. Possibly the video card, but my best guess would be motherboard failure. I really wouldn't be able to tell for sure without further testing.
 
Yeah, I took it to a computer repair shop and it actually was the motherboard that was fried. I'm having problems with another laptop as well.
