Trouble with emachine 700G

I needed a 2nd monitor and my grandfather gave me an old machine 700G 17" LCD Monitor. This thing is from 2006. I was shocked to see how old this thing was. But I took what I could get and bought a VGA to HDMI adapter for like $8 so I could use the dang thing. Fast forward to today, everything is plugged in and I hit the power button.
Nothing...
I'm super bummed out because it fits perfectly on my desk and I didn't have to pay for it. I tried looking on the website that was advertised on the back (www.emachines.com) and it took me here.

What can I do to get this thing working?
I will try to answer any questions anyone may have.
