Blank screen on laptop. Not working on external monitor.

I bought a used Dell Inspiron 5150 for spare parts. Well it came with everything, but was told the video was not working(No image on the screen) It powers up, fan turns on and about 10seconds later the fan will turn off. The "Power" light will still be on, as well as the computer(Have to push the power button to shut it down)
So I figured might as well try to fix it.
I hooked it up to an external monitor. No picture. Swapped the ram to see if that was the issue. It was not. Took it apart and swapped the graphics card for a known working one. Didn't solve the problem.
Is the motherboard possibly gone? Or what else can I try?
