Hi all, I recently got a used thunderbolt monitor and it seems to be that the backlight no longer functions. If you take a flashlight and shine on the screen, you can see the image and it is not lit - according to ifixit, that's the issue. Im a student, so I hope you can imagine that I'm on a tight budget and would like to get it fixed, or fix it myself so that it's functional. Any thoughts on what's wrong, costs, etc. would be greatly appreciated.
