Why does my LG G4 randomly turn off and won't turn back on?

[AC Question]

My phone is turning off and it keeps coming on to the LG screen as if it is about to turn back on, but then the screen goes black again and the same thing happens again.

It may be best to contact the seller about that, or LG customer support.

This is happening to me too. Any luck with a fix??
