LGG3 completely stopped working what should i do ?

[AC Question]

Yesterday, i was just browsing in youtube , when my phone turned off. It would not turn back on, i took the battery out, and put it back in. Now it would turn on, and go straight to a blue screen then turn off again ,.

Welcome to Android Central! Let it charge overnight on a wall outlet undisturbed, then try powering on again by pressing and holding the Power button for at least 15 seconds. If the problem persists, see if a different battery helps. If not, then the motherboard may have failed.
