Dead Display, Everything Else Working
This is on a late 2009 iMac 27" A1312.
Was replacing the ODD. When I put it back together there is no display at all. It chimes and boots, I got into it via Screen Sharing with my laptop. I am currently backing it up.
Checked all cables and temp sensors, they appear fine though the Vsync cable is looking a little worn.
My main question, since the display is completely dark, no faint image, no lED bars, nothing at all on screen, does it sound like a power supply problem, or if the connector on the logic board right over the video card is boo booed, and not letting any video signal in to the monitor will it prevent startup of the lcd itself.
I don't know the order of steps for power up of the LCD. Also does the front plastic have any sensors on it that might prevent the kid from powering up?

Is this a good question?
