If you don’t get an image via HDMI on your TFT/TV, sometimes it’s because of a wrong setting… and if you can’t connect to your Odroid with SSH (to run odroid-config), you have got a problem but just a small one.
Put the SD in a Card-Reader and connect it to a Linux-PC.
The first partition, a fat partition will have a file named boot-auto.scr copy it to boot.scr (replace the old boot.scr there)
Now your little gadget should boot with an image on your screen
