Responder a:Disconnect thunderbolt cable from displayThis post truly saved my company money that would have been spent on buying an entirely new display monitor. I looked on several sites for the replacement display cable before I finally found an inexpensive one, $18.99, on Amazon. The cable came in great condition. My only nervousness about doing this repair was removing the screen with fear of not being able to reattach it the same. I assumed that the glass screen display was held by tape. To my surprise, the screen attaches with magnets. AWESOME!! It took me over an hour, nearly two hour actually, to break down the monitor in order to get to the cable. It took me about 20 to 30 minutes to put all the components back into place in order to test the new cables. To my frustration, it did not work. So, I just walked away from the device and went home. I returned in the morning and took the monitor apart again to find that I'd forgotten to connected ONE cable. LOL After putting the device back together and connected it to my Macbook, the display immediately work...
