Galaxy S7 Edge - green notification light keep flashing - black screen, not responsive

[Bartkosz]

Hi,
my S7 Edge got black unresponsive screen, and the green notification light keep blinking. I cannot enter to recovery mode or to safemode. I try to reboot it, but it always come back to the same situation. I also tried to charged it to full but it nothing help.
What's interesting that when I click the home button the screen flashes blue for a sacond and back to described status.
Anyone has the same situation and solved it or got the ideas what to do.
Thanks for any help.

Edit: it vibrating when I lift it up from the table

It sounds to me that if you've exhausted all the self help reboot troubleshooting tips available to you then the next step would be to take the phone to a Samsung Experience Store or Samsung Service Centre @Bartkosz 

I wish you all the best with this situation.

Yeah, I think it can be a damage motherboard, so I will take it to the nearest Samsung service and see what they will tell me.
Thanks
