Cinema HD Display 23" won't turn on to a Thunderbolt port
I had Apple Cinema HD Display 23" on my 2011 MBP 15" with Thunderbolt to DVI adapter and it work since first day put on my MBP 15".
It quit to turn on since March 2013 on my 2011 MBP 15", power fine, USB fine, it just won't turn on.
However, I use Cinema HD display DVI adapter connect to my old MBP 17", it turn on normal, everthing fine.
I really like my 23" Cinema HD Display back to my 2011 MBP 15".
Any ideal where go wrong on my 2011 MBP 15".
