Spectre x360 turns on but doesn't boot or show anything on screen.

Spectre x360

I recently replaced the motherboard in an HP Spectre x360.  The machine turns on, but does not show anything on the screen (either the built in screen or a connected external monitor).  It turns on both while plugged in or running on battery, but aside from the keyboard backlight and power indicator light turning on, nothing happens - no beeps, nothing on screen.


I've re-opened it up and double and triple checked all the connections and hardware and I don't see anything wrong.  


Before I assume that the new system board is dead-on-arrival, is there anything else I can do to diagnose this?


I don't know if it's relevant to this issue, but the reason I replaced the board in the first place is that the built in display stopped working, but the machine was still usable with an external display.  When I pulled the old board out, there was a very visible burn mark on the display ZIF connector on the board.
