Will reinserting the display work? Maybe the connector lost Connection between the display and the motherboard.

Outta nowhere my Note 4 remains black.

There is life in the phone. Its still vibrating and the LED on top of the phone is still working.

What I did notice at the same time is when i insert a charger. The phone vibrates and its LED light on top turns orange/red as usual. When ejecting the charger. That light still remains on.

Booting in recovery mode doesn't work. But once again the phone is vibrating when I'm holding its recovery mode buttons.

I have no idea what went wrong with this device. I didn't drop it and whatever.
