Jetpack 5.0.2 No video

I just updated to Jetpack 5.0.2 I was running Jetpack 5.0.1 fine.

What is going on?

Please help

What do you mean "No video?
Please provide more information, then we can know what issue might be.

The monitor flickers, but I get no video signal

Do you re-flash the system image through SDKManager? And use DP or HDMI port?
