Black screen after change superdrive for an SSD
I opened my iMac 27 i7 (late 2009) and when I opened the computer I broke the backlight sync wire. No when i turn on the iMac it can boot but the display its black, and I think that I couldn't see any thing when i tried to use the flash light of my phone on the display.
If i connect an external display i can use the computer.
Does this problem with that wire cause this, or may be it's some other thing that it's wrong?
Thanks for your time guys!
Is this a good question?
