NVIDIA Jetson Nano - No Display

Hi I bought my NVIDIA Jetson Nano from Amazon,

I followed the steps carefully to make sd card bootable and using 5V, 4A power supply with HDMI monitor with NVIDIA Jetson Nano.

The green LED turns on and remains on but no display appears on the screen. If I attached Keyboard or Mouse with the board, they didn’t powered on as well.

What could be the problem? How can I identify the problem?

Thanks

you need flash the systerm into one TF card and insert TF card to NANO

Thanks,

I am using 32 GB SanDisk HC I card and followed the instructions at https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-devkit#write (for windows) to flash my sd card.

if you use 5V 4A DC power,don’t forget to inset a jumper as follows:
