My Thunderbolt Display is unresponsive...

About a year of fine use with this great display, and now it will not respond to input. First, I noticed that it would not awake from sleep; unplugging and plugging-in the Tb display fixed this. However, upon trying to power cycle the display (by unplugging it and letting it sit)—as well as performing both an SMC and PRAM reset on my MacBook Pro—I've seen zero response from the display.

What other possibilities or methods are there? I'm running 10.14.16 Mojave, by the way. Here is what the system profiler says when I have Tb plugged in: nothing.


Is this thing just dead for good? Perhaps I leave it unplugged overnight?
