LG logo appears then screen goes black

[AC Question]

Lg G4 - picked up the phone to a powered off screen (was working fine a few minutes earlier) then when I tried to turn it on the phone will boot to the Lg animation, stay on longer that usual, then go black and become unresponsive. I have tried taking out the battery, plugging into the charger, and even pulling up the factory reset screen (it won't even respond to that command).
