Vizio TV shut off will not turn on

I have a Vizio 50in TV I was getting into bed when I hit the remote I don't know if it shut off on its own or if I did it but the TV shut off and will not turn back on I tried unplugging the power supply when I plug it back in the TV turns on then off really quick( the red light in the corner turn on but then off really fast). When I went to check the back of the TV the phone jack Outlet was still lit up. The TV has been perfectly fine up to this point. please help!!( when I plugged it back in the wall the little light in the corner came on then it dimmed off, still won't turn on)
