Please help - Brand new 8831 conf phone won't boot

Not sure how to troubleshoot these new phones, but when I power the phone via wall power (power cube) or 48v POE, the phone LEDs stay on for a second or two then go out, and then the phone does nothing.  No display or additional blinking lights - nothing.  At first I thought it was a bad power cube, so I tested on a working POE, and nothing.  I'm wondering if this was shipped DOA or what.  Any suggestions would be greatly appreciated!
