Laptop without screen, factory reset and cannot get to work hdmi

I factory reset my laptop, and it will not go to the external hdmi component. I removed the screen and it still will not output. The ribbon cable is not connected to anything. Any suggestions on how to fix this? I can't remove the drive from the laptop or anything like that.
