Banana pi m5 doesn't start (no leds)


I received some times ago a banana Pi M5, I followed a tutorial to load Armbian on the SD card (, I chose the correct board, everything seems fine. With the SD card on the M5, when a connect the USB C charger and the HDMI port on it, I have nothing on the screen, not a single leds ON (no red Led nothing). I contacted the after sale, they told me it was an issue with the boot on the SD. But even without the Boot I would expect a power led ON. (The USB C charger works fine with other devices) Is it really an issue with the configuration on the SD or an issue with the board?

Thanks, Clément
