Can some one post a link where I can read that flowchart on how to isolate issues if no images and no power on Apple’s thunderbolt display?

@lovecd I do not have a link but I do have the right flowsheet now. Previously, I believe I erroneously posted the one for the Cinema Display on your other question. This flowsheet is for the Thunderbolt display “No Power situation”. Subsequently check the test points on the power supply.
