Paweł Kadysz Disconnected the power cable from the display and very slowly connected it back. The screen flickered for a couple first tries and then it just lit up normally. I think I jump-started the display :P
Ian Prince Quite by coincidence just yesterday I “fixed” my colleague’s dead Cinema Display by unplugging everything (including the power supply) for three minutes to bring it back to life!
Ian Prince Ah what was the one thing you tried?
