My LG G3 is unresponsive

[AC Question]

My LG G3 will not turn on. I left it on charging cord all night, and it cannot get past the LG start up screen before becoming unresponsive and going dark. The red charging LED indicator does not show up. I have tried switching batteries and removing the SD and SIM cards with no change.

I was going to suggest pulling your battery - that usually works when my G3 bugs out on me - but I see that you've already tried that.

How old is your G3? Any other issues before this one? How about new apps - anything installed lately? Lastly, has the phone experienced any drops or water damage?
