New Element14 Raspberry Pi 3 Model B out of box: Per instructions, formatted (FAT32) successfully a MicroSD card, inserted it, connected USB keyboard, USB mouse, HDMI monitor, Ethernet, and lastly power. --> No video output, no sign of life aside from red LED on board at power connection. Debug effort: (1) confirmed HDMI channel to monitor via another test source - no issue with the monitor, (2) alternate power source assuring 2.5A capability (@5V) - no issue with the power source. What next? (There was no user guide provided with the board to offer suggestions.)
