Thank you for the guide (und die deutsche Übersetzung!),

I completed the whole thing including the removal of the logic board with the A1706, 13inch touchbar 2017. I just used it as an opportunity to renew thermal paste and give everything a deep clean including the fans which can easily be removed too when the logic board is out already.

Same happend to me. Let me know if you find a solution. So far I am using “TouchBarServer.app” to compensate. I think I found it on Github

Thank you for the guide! Und die deutsche Übersetzung natürlich!

I could change the display successfully even though I dont have a lot of experience in this stuff. I have to warn though that these models are very fragile; I probably broke my touchbar in the process. Its not responding to touch interactions anymore.
