Computer screen blank, shuts off when unplugged

[jjones86]

I haven't used my computer in a couple years due to the screen being broken. I got it in 2013. I repaced the screen today, but now it is showing blank. I also noticed that it shuts off when I unplug the charger.

I changed the computer screen because it was cracked and i have a new battery because the old one was broken. When i power it on, the screen remains black. It comes on but screen is black. 

So I can't do factory reset because the screen is black.
