Hi, Today I was using my MBP and Thunderbolt Display just fine. I go downstairs, have dinner, wake the computer from sleep and suddenly it isn't working. The computer will recognise it - sound plays, and you can move your cursor to it - but no picture displays, just a black screen. I tried restarting, unplugging, plugging back in but alas it does not work. I have a feeling that this is a hardware problem, andI bought it in December 2011 so have no warranty left. Am I covered by Section 14 of the UK's Sales of Goods Act? I'm really, really disappointed because the display was fantastic to use, and just like that it stops working. Annoying to say the least. Can anyone help?!
