Hi There.
I have a problem a back screen issue.
The fans turns on with the hdd and DVD drive.
I checked the onboard diagnostics and LED 2, 3 and 4 are off.
I have replaced the PSU but but still a black screen.
I have replaced the cmos battery but still black screen.
I have baked the gpu but still black screen.
Ask for any info about Imac.
Edit.
[br]
I forgot to mention I plugged in a different keyboard when it was working and when 15 min past it crashed and I could turn it on but it would crash less then 10 min in it would crash. The next day it would not turn on I have the issue now.
