2010 iMac black screen mystery
I have a pretty mysterious case with my 2010 imac 27 inch. The screen suddenly went black. The computer boots up fine and runs with an external monitor. When I shine a light into the lcd display i can see the image that should be on the screen: so the panel is recieving the image but the backlight isnt working. I replaced the led inverter board, but nothing changed. So i replaced the whole lcd panel, and no change.
I did reuse the displayport cable from the old panel, so I suppose that could be faulty. The thermal sensor seems fine because if I unplug it the fans go crazy.
What else could I be missing? I'm worried I've reached the end of my technical abilities and am really stumped.
Is dit een goede vraag?
