Won't power on/boot -- kickstarter A64 2GB

[tllim]

Kickstarter backer, finally getting to playing with my A64+ 2gb

Using the new Etcher image burner on a Transcend 300x 16gb card UHS-1

No matter what image I use (Android, Linux, RemixOS, etc.), won't boot.

Power supply is a 5V 2.5A power supply I use with my Raspberry Pi 3 which works fine

Symptoms:

Red LED works/on when USB power is plugged in
HDMI out makes the monitor turn on, then off because 'no signal is detected', turns back on, turn off no signal -- keeps repeating

I'm unsure if this is power supply, memory card, or simply bunk A64 related.

Any help?

I have the same issue.  Did you get this resolved?

in general, mostly due to power supply (make sure is 5V 2A, don't use smartphone charger) and microSD card preparation.
