New Latte Panda 4/64 Won't Boot Linux Image After Install

I've tried the pinned link here about the Ubuntu Clonezilla image on my new LattePanda's, but while the clone step works, upon reboot the monitor goes dead after the BIOS screen loads up, and never wakes up again. My router never has the LattePanda trying to lease an IP (connected wired over RJ45), so it doesn't appear to be booting but failing at video.

I'm kind of at a loss as to what's going on here. Has anyone else encountered this?
