Black Screen Of Death On iMack late 2009
I have a iMac late 2009 (Ver. 2309). My lcd is black on boot, but I can get video on external lcd-TV through minidiplayport to hdmi. The problem is that I have to do the smc-reset every time I start my iMac. Not the usual smc-reset, cause I have to unplugg and wait 30-60min before plugging inn the powercable, and wait 5sec before power on my iMac. Now it boots up with the external display, and it works until I shut down the OS X.
My iMac display behaved the same way until I messed up my vlcd connector.
I have also tested PRAM-reset without positive results.
Any ideas what's wrong with my iMac?
