GENERAL No boot, green light, Trinity

[gagamel1]

Hello,

maybe u can help me.
I got an Xbox Slim Trinity with a boot error.
If I turn on, the mid LED is green and the fan is not running smooth, like a stutter.
The Xbox has no RGH.
I think its not even booting. I dont get an error, it just stays like that.

Here is a video:
