Got my thunderbolt display completely black, nothing shows up on screen, no sound from speaker, no iCam, and it won’t charge my Macbook Pro laptop either (the charging light is not on at all). Is there a way to diagnose which component failed, PSU, logic board or thunderbolt cable itself?
Thanks for advise!

Hi Dan, here are the pictures I just took, the TB cable looks good physically. Unfortunately, I don’t have the separate TB a as available, but I can buy one if it is necessary. So, if I get the images showing up with the separate TB cable, does it mean the internal TB cable is bad? And if no images with that separate TB connected, which means the logic board is bad?
