Device will not turn on SGH-I317

I was playing a game on my phone a few days ago and it just turned off, battery was at 76%. No warning no nothing. Changed the battery and still nothing. It wont make any noise or vibrate when it's plugged in. Tried using several different cables and wall plugs as well as different outlets. Still nothing. Seems the phone just up and quit when it had no problems before it just shut off. Is there anything I can do to fix this or is it just dead completely?
