You're not speaking to Apple here – just to other Apple users.
According to MacTracker, Apple sold the Thunderbolt Display between July 2011 and June 2016. Since Apple discontinued it more than seven years ago, I believe they would consider it "obsolete" for repair purposes. That means that Apple would not stock repair parts for it, or provide paid repair service for it.
One thing I have read on these forums is that the video cable attached to the Thunderbolt Display can go bad. If that's the problem with yours, running a Thunderbolt cable into the Thunderbolt daisy-chaining port might work around the failed cable.
