NVIDIA Jetson TX2 doesn't boot up

I have problem with booting up the Jetson tx2 699-83310-1000-D00 H.
First, I didn’t have the mini HDMI cable so I tried it to flash with sdkmanager on the host computer but, didn’t see device name when I run ‘lsusb’ command (I pressed the ‘force recovery’ button when it’s turned on).
So, I bought the mini HDMI cable and checked it on display. But it shows nothing on the display. I see the green light on the board.

How can I fix the problem? Anyone help me, please.

It’s working now after I turned it on. HUUU.
