Hi

I change the hard disk of my Imac

then I reassembled it, but the screen didnt turn on but when i pluged and external monitor it worked fine

i searched a bit on the web i found out about the 4 diag LEDs when i checked my MoBo only the bottom 3 LED work then top one doesnt light up

i though maybe i ripped the screen ribbon so i replaced it with other one but still the same problem

Ist dies eine gute Frage?

I forgot to mention that

I already use the display port and it's OK.
