TX2 not booting, no HDMI and fan is not spinning

I got my brand new Jetson TX2 and followed the instructions on quick start guide.
Upon plugging in the power cord and pressing power button, 2 green LED lights turn on. However, there is no display on HDMI nor the fan is spinning.

Please help.

Hi chikeunglee,

Do you have UART debug board for boot up message?

never mind. It turns out to be cable issue. it works now. Thanks.
