Got this board and the black light doesn't work and I'm assuming this missing component could be one of the faults and if it's not then im sure it's still a problem that there's something missing. Help anyone? Definitely appreciated.
Is this a good question?

JRH, the part your board is missing is reference designator L8300 which is a 220ohm inductor (ferrite bead ) in a 0805 package. I believe that the assumption is being made that it is a "solder blob" to bridge a component. It is absolutely not. From your image it is very clear that you still have both the solder pads for L8300. The component is not a fuse and it is not bridged. The only reason it does not look normal, is due to the package size compared to the other components.

So the backlit on the display assembly is not working. I burnt the fuse out before when I didn't fully clean water damage properly on a macbook pro. Looks like you'll have to find another fuse that is the same for that spot.

This does not look normal. What is the history of this machine?
