Why won't my HTC One M7 turn on?

A

AC Question

HTC One M7 Won't turn on. No Leds, won't connect to PC.

This morning, The One worked just fine, like normally. (at 94% battery)
I wanted to check if the sound of some speakers worked, so I connected my phone with the speakers ux). When the aux cable was in the jacket, the phone just turned black and didn't start again. A friend who was standing next to me put the aux jacked in his phone. Everything worked fine.
When I came home I connected the One to my laptop but nothing showed up and even the leds didn't turn on. So i started searching on the internet for a solution.
Nothing worked.
I tried this:
Powerbutton + Volume up (30+ sec)
Powerbutton + Volume down (30+ sec)
Powerbutton + up & down (30+ sec)
Try to charge the phone (and keeping in in a wallplug.)
Does anyone have a idea on how to fix this?
