Chosen Solution

Just one day went turn on my imac and there is a start up chime and you can hear fans and everything. Once its had a bit of time for start up if you hit escape for example you can hear the notification sound like normal. As far as I can tell its starting up but display isnt outputting anything. I have tried hooking it up to 2 different external displays and nothing goes through. Any ideas?

There was a recall on some of the 2011 models for this issue . Please give us the last four figures of your serial number (located on the bottom of your stand). UPDATE 3/24/16 MacBook Pro Repair Extension Program for Video Issues https://www.apple.com/support/macbookpro
