As the MagSafe does have power (the MagSafe cord is either Amber or Green) ideally you should monitor [https://www.coconut-flavour.com/coconutbattery/|CoconutBattery] to see what’s happening.

As the system doesn’t see the display could be a ThunderBolt cable issue or a flakey logic board connector. As you didn’t tell us what your system is I can’t dive any deeper in this direction.

How is the cable? Any noticeable damage or the cable is a bit sloppy within the connection?

How is the cable? Any noticeable damage or the cable is a bit sloppy within the connection? If you have a spare TB cable you can also use one of the displays ports to feed the video from your system (by passing the attached cable) does that work?
I would try a second system if you can or if your system has a second port try that as well.
If we can remove the cable and the system then this gets into the logic board within the TB display. It could be a cold solder joint or failing component.
