Apple tv 4 Probleme Screen flashing

I have bought a Apple tv 4 in december 2015. I had a great experience with it.
But since a week ago it is always crashing no matter what app i use. If for instance i want to view a Youtube video in the Youtube App before the video could launch the apple tv crashes and brings me automatically back to the homescreen. Same in the Apple movie trailer app and in Infuse media player.
Sometimes i get strange lines on top of the screen ( see screenshot)
I also get a flickering apple logo (video to see what i mean)

What i have tried:
- Connected a USB C cable on my apple tv and restored and updated to the latest firmware "3times"
- Connected a different HDMI cable
- Rebooted my modem and network

Is someon encoutering similar problems ? What should i do ?
Should i bring it back in to warranty or are there other things i could try to fix this ?

Thanks in advance for your help
