Any ideas on how to debug or fix this would be appreciated.
2 suggestions: one fairly easy, one less so.
#1
I have an Apple 27" Thunderbolt display on my Retina iMac. I have to use a separate external Thunderbolt cable, *not* the built-in one.
The built-in captive cable works, but then the auxiliary ports on the back of the screen do not and both adaptive brightness control and direct control via System Preferences fail.
So, try a different cable.
Looking for a replacement cable lead me an article that says that removing the cable is only possible by disassembling the display [1]. Was that what you had to do? The cable does not seem user-removable at my end.

I know it's not very helpful, but I'd try with a different OS, e.g. Windows.
I have failed to get my device working with another non-Apple computer, and Googling for why suggested it probably won't work with anything else.
That's also possibility. I probably should've tested before quickly wiping Windows ... I was encourage by the fact that there were many references to this display working on Linux. - https://www.reddit.com/r/linuxquestions/comments/68lj11/linux_thunderbolt_su... - https://www.phoronix.com/scan.php?page=article&item=apple_thunderbolt_linux&... Might be the thunderbolt 3-to-2 adapter I'm using, as referenced at - https://bugzilla.kernel.org/show_bug.cgi?id=189731 But unfortunately I would not have the time to install Windows on my laptop.
