Why will my LGG3 not turn on?

[Android Central Question]

About four months ago my LGG3 suddently went black while texting. I will say it is nearly three years old but it was working fine beforehand and I never damaged it too bad. I already tried another battery and charging but nothing. Any idea to what happened?

Welcome to Android Central! Probably a motherboard failure. The G3 and G4 were both plagued by issues like bootloops. There's probably not much you can do, short of getting the whole motherboard replaced.
