I've got some sign of life on my gas fireplace but no ignition, just a glow under the logs. The only thing I know for sure to do is buff the flame sensor, which I have done, and still no ignition. As far as I can tell, all gas lines are turned on. Any thoughts?

Is the pilot lit? When you turn the unit on what happens?
Does the valve 'click' when the switch is put in the on position?
Do you have a better picture of the gas valve?

Here's a video of the guts of the fireplace.
I believe the pilot is lit. There is a little glow under the logs when I flip the power on.
No click that I can hear.
I also have a still photo of the gas valve if this video is not clear enough.

First step: how are you trying to turn it on? Wall switch, remote, etc? Check for operator error.
Second step: check all wire connections and grounds.
Third step: check for voltage on green wire to valve when you turn it on.
Fourth step: check for physical obstruction of burner orifice.
Disclaimer: this is what a technician would do. Don't try anything you are not comfortable doing.

In my experience Sometimes that along with excersizing the valve will cause the problem to go away. And Sometimes it will not and can get worse. I see this more with newer electronic valves than the millivolt valves personally.

I saw your thread on the fireplace's issue in 2014 where your fireplace off and on intermittently with a clicking sound. Mine has the same problem. Did you find out what was wrong then? Thanks for your reply.

to add to Daksys comment clean both the probes and the edges of the hood that head towards the probes i have found the green brillow pads work really well just make sure that the assembly is cool first.
