I have a 2011 TBD that will display an image for just a fraction of a second prior to going to a black screen. -- I can make out my background image just prior to it going black. The display is recognized by system information even while the screen is black and the display will play audio from its internal speakers. The TBD had AppleCare on it until 01/01/2015 and I am currently in talks with a senior advisor on getting a CS code for the display. If I am unable to obtain a CS code I would like to attempt to repair the screen myself as I am an ACMT, ACSP and EE student that can't afford spending $900 to replace a display that is only three years old. I mean, I have a Cinema HD Display from 2007 that works great still to this day! Has anybody else experienced this issue or have suggestions on repairing the display? My first guess would be an LCD panel controller board.
