NUC7i5BNH won't power on

[MikeM]

My trusty NUC worked fine Thursday evening, but wouldn't power on Friday evening.  There are no recent changes (BIOS updates, win10 patches, etc.).  There are no lights on the front panel.  There is a green standby light on the mainboard itself.  The mainboard is buzzing, but I don't know if the buzzing is new or not.  I tried the following:

1) unplugging for 15 minutes and plugging in and hitting the power.  No change.

2) holding down the power button down.  No blink codes.

3) inserting headphone into the front jack and holding the power button down.  No beep codes.

4) tried a different power supply.  No change.  No front LED's or power on, but still got the green mainboard standby light.

4) removed all the components (RAM, SSD, USB dongle for keyboard).  No change.

5) Removed the CMOS backup battery for 15 minutes.  No change.   

6) visually inspected both sides of the board.  I didn't see any damage. 

Anything else I can do to diagnose the problem?

I tried the CMOS jumper sequence described at NUC7i5BNH Will not power up - Intel Communities. No change.
