ZED BOX Orin is not working

I have ZED BOX ORIN

Not booting at all. LED is ON.

Even if I connect OTG not showing in Host pc used lsusb, serial connection.

Tried to flash using USB.
Flashed using zedbox_all_usb_flash_6.2.sh
Successed on log and when I plug it on ZED BOX and power on. Waited 10 minutes nothing happened still no HDMI output, no Serial, no Recovery mode signal on lsusb.

I have another ZED Box.
Which is not working on full power mode.
When I power it LED is on for 5 second and turning off.

I think both has Hardware issue. I did not open it.
Bought on December 2025.

Need at least ASAP consultation.
Thanks.
