I hope someone can help. I have been on the case of my iMac late 2009 (27 inch) for over a week now. At the end of the robe here (and possible fixes found online and in the manual)
# The issue: screen went black and although the computer power on the screen never really gets going. It is not black black but appear to have some light going but I can not see anything.
# tried solutions: troubleshot and fixes from the official manual for this model. This includes connecting external monitor which works all fine (so not the video card). I can work from the external monitor as per usual. Testing if all 4 led diagnostic lights comes on as expected (they do). Checking cables connecting the lcd screen, and I cannot find any immediate issues. And of course all the suggested resets (SMC, PRAM etc.) . Flashlight test (i cant see anything at all). And the Brightness is set correctly.
I have attached a picture of what the screen looks like (Sorry for the less than great quality - difficult to capture)
The manual suggested a next step to be to replace the backlight board (but someone noted it was only likely to be the issue if i could see the Apple logo very very faintly when turning the computer off (i dont see anything). Another next step potential fix from the manual is a new LCD screen. However, that will be too costly at this point I think - especisææy given that I might not be the issue. I just really liked the computer and it worked very well until now.
I am grateful for any further insights!
thank you so much for your reply. I have added pics. Hope it is was pics like these you were requesting.

thank you! I also tried to take a video with an inspection cam, but the metal shines back too much. Perhaps I will try again during daytime tomorrow.
