Computer Screen Shuts off During Boot Up
Hello,
My iMac turns on, chimes, then begins booting up but then the screen shuts down during boot-up. I can still hear the fans running in the back but there is no display?
Any of you guys know what this could be?
Thanks, Alex.

What happens when you connect an external monitor to your system are you able to see your desktop or, use a flashlight and press it to the screen at a sharp angle are you able to see your desktop then?

Hi Dan so I connected it to a tv and its working through that! When I try the flashlight trick I see no sign of icons behind the glass.

Last test here: In a darkened rm after the system is started do you see a slight glow in the display along the edge (dark grey just not pitch black). If you do that just verifies the back light circuit is working and only the LCD has a problem.
Jump down to my answer below after you do the test.
