17" inch Pro - LCD flickering and at times sudden black screen
Dear Community,
since I bought my PRO almost 2 years ago in the beginning when I open the lid I had at times a flickering screen but I resolved it but closing the lid and reopen which solved the issue. Now I have upgraded to Lion OS and since this morning I have a constant black out on my LCD every say 5 to 10 min. After awhile it comes back a life, or at times when it comes back after 10 sec it brings me to the user login screen.
I have searched Apple support, google but didnt find anything relevant to solve my issue however noticed that it is a very common problem for many poeple.
Pls dont tell me to bring it to Service or replace my LCD, I read that already but i wanna know what is the cause of this problem.
For any input or advise (SOLUTION) to my problem I really appreciate it.
MacBook Pro, Mac OS X (10.7.2)
