I have just received a jetson nano, and flashed the image onto the sd card and plugged it into the nano. I first powered the nano with a micro usb cable and it worked fine - other than a few times the screen flashed and these weird green lines that were randomly around the screen,
I then dcided to switch to using the barrel plug as the input, with 5v and 4 amps going in. I bridged the j48 pins and plugged in the barrel plug, however after doing so I could not get any HDMI output. THe green light is on, but no screen. Even when I switch back to the micro usb cable. ANy help would be appreciated, thanks.
