I have been using the same Jetson TX2 for a while and it has been in use for years before I started working with it. It is running Ubuntu 16 and is connected to a windows 10 machine via SSH. We had not had any connection issues until recently when it wouldn’t connect via SSH, but a quick restart fixed it each time until now. Now it will not connect and when I plug a monitor to it nothing shows up, however, all 4 red and green lights turn on like normal. I am new to this kind of stuff so any help would be appreciated, and I can get you any more information you need. Thanks!
You’ll need a serial console boot log. See:

Also, a lot depends on if this is the developer’s kit sold by NVIDIA, versus something with a third part carrier board.
You could just flash again, but that wouldn’t tell you about what is going on.

I am using a dev kit. I am trying to do the serial console boot log but it will not connect to my host PC, I have the pins plugged into the right places on J21, but it is not showing up when I run “lsusb”, do I have any other options?
Is this a micro-B USB cable at one end, and a full-sized type-A plug at the other end? Basically a “charger” cable. If so, then that is correct, but if it is an actual charger cable and not the one which comes with the TX2, then know that about 2 out of 3 “charger” cables have terrible data line quality and it may be due to the cable itself that it fails.
On the host PC, if you run “dmesg --follow” (which monitors logs in real time) before plugging in the Jetson, do you see any log messages as a result of the cable plug-in?
