I purchased dragonboard 410C couple of weeks ago. I powered it up today and followed the quick start guide video on Arrow web site, connecting power, keyboard and a mouse. Pressing the power on switch on board makes user LED 4 light up for sometime after that it shuts off and no HDMI output even after leaving it for a while. The switches on the bottom side 1234 are all to the right, i.e, no HDMI_SEL, no USB_HOST, no SD BOOT, and no USB BOOT. Can you help or is the board defective and I should ask for replacement?
