My mid 2011 21.5” iMac has been acting very weird.
So there is no image displayed on the screen, but If I shine a torch on the screen I can see everything. This leads to the conclusion that the backlight has failed. I also know that it is not the LCD that is the issue as I have another iMac of the same model which I plugged the LCD into and it worked fine. I replaced the LED Backlight driver board and still I get the same result.. The Image is only visible under a torch light.
I am open to any suggestions/ideas of what the problem would be.
Some other info:
1. The image is also visible on an external screen using the Mini display port.
2. I also managed to get to the recovery window just by using a torch so its not the HDD
3. All indicator lights light up, including LCD one which means the computer is communicating with the LCD
If it is needed i can upload photos.
Cheers

Could you please give me some more in-depth information so I can let the person I got the backlight driver from know? Also below are images of the connectors on the screen.
