I saw something similar a few days ago. After a reboot from archlinux, I got no output from BIOS & grub2 via HDMI(serial output worked). I got HDMI output once Linux had booted.

The problem fixed itself after a while. Disconnecting the device from power for a while might have done it.

All the best,
