Thunderbolt Display goes randomly black, I have the latest updates. What to do?

For years I had no problems, suddenly it started. When the display is black all I can do is reset everything several times.

But after that it is still happening again after a few hours of work.

iMac (27-inch Mid 2011), iOS 8.3, null
