My Lg G2 won't turn on

AC Question

I looked through different forums but I didn't find anything that was exactly my problem. My phone was working perfectly fine and it randomly turned off when I tried to use it. It's done this before, so I thought nothing of it and tried to turn it back on. This time, however it turned on normally, but as soon as the start screen showed it turned right back off. I thought maybe after charging it all night that maybe it would work again. Well, it's the next morning and it's still doing the same thing. If I can't get it to work by myself I'll go by Verizon later today.
