In this case your backlight is still working, but there is no video on the screen, meaning the LCD is bad, the cable is bad oir the onboard video is bad. > > B) Is the screen completely black? if yes, go to your Mac > Store. Shine a flashlight on the screen at an angle, if you can see your desktop then the problem is the backlight or inverter. If you still see nothing, then both the backlight and the video are kaput. Can you connect an external monitor and get anything? if not the issue is the onboard video, which means logic board replacement. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.
