Jetson Nano not booting

Hello everyone, I’ve been having lots of problems with my Nano for the past few days because it wont boot.
The monitor screen is black because there is no video output from my nano although the power led is green, I’ve been using hdmi and display port cables, the nano is powered by a 5v 3A power bank so there shouldn’t be a problem.
Also I’ve flashed the sd card twice, does anyone have an idea?:D.

Thank you!

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
