Red led and nothing eles

psygnosis

Ho guys, today a archive to run an orange pi one with a 5v dedicated power ac (not usb one used for smartphones).
i try either official. Ubuntu ldxe image and armbian (burned with etcher on Samsung sd)

On my first try I saw on my 720p TV (hdmi) some write then nothing else, no signal. And a green led lights up with a red led blinking.
on next tries no video signal at all and only the red led is still light on.

I can't try android img cause phoenixcard app give me error.

Is there something I could try? Thank you or just you can tell me what that leds means

Usually suggestion would be: change another power supply, try to write image again, and change another SD card. But i think you are not the first time to run development board, maybe you could try to print out the debug lof to analyse what error it is.
