Tablet freezes on strartup

[AC Question]

Hello,

I have a problem with my tablet since yesterday. It´s stuck on the booting process. Whenever I press the power button the first image appears and thats it. I´ve tried to just leave it in this state but even after two hours it still shows the first image. When I try to charge it up, it also just shows the battery. Normally it would play and animation to indicade that it´s charging up. Before I encountered this problem it frozze on me while normal use. Then it rebootet and failed doing so.
I can not enter fastboot mode. I´ve tried to detect the device with adb tools but it´s not showing up in any state.

Infos:
Tablet: TrekStore SurfTab brezze 10.1 quad
OS: KitKat
Age: ~ 1 year

Thanks.

Welcome to Android Central! Chances are that either the firmware became corrupt or the motherboard is faulty. There's probably nothing else you can do. Is it still under warranty?
