My phone turned off after making a weird buzzing sound??

[Android Central Question]

I don't know what happened, I was just on facebook watching a video when it made a buzzing sound and turned off. It won't turn back on. Please help

That could be almost anything, from water damage to a destroyed motherboard. It will have to go into a repair shop for a diagnosis. (I assume that you already tried charging it for about 4 hours before trying to turn it on.)
