Surface Pro 4 - does not boot- black screen - keyboard lights up.
I've tried every trouble shooting suggestion from Microsoft and a few others found in a Google search.
I've tried three different power sources and a docking station with the secondary monitor.
The unit was not dropped and it was in use when the screen froze, on the first attempt at a re-boot, only black screen.

The issue fits with what I've read about a known resister issue with these units.
