My LG G4 turned off and won't go back on

[AC Question]

My phone is 2 months over the year warranty and today it won't turn back on. It shut itself off overnight. It partially did turn on for a minute but was on the LG screen and that screen kept popping up when the next screen should've been the AT&T one. Pressed the power button again and it went through the cycle and asked me for my password. After I entered it it froze ok no the home screen and shut off and nothing ever since.

Welcome to Android Central! So it isn't bootlooping? Have you tried replacing the battery? Or pressing and holding Power for at least 15-20 seconds?
