Hi! I just opened up my iMac 27 and put it back together. When I fired it up I heard a little “pop”. Opening it up again, I can see a fuse (?) has melted near by the DP power port:

I might have been clumsy and put the cable the wrong way, making the fuse pop. It seems like it should be replacable with a decent soldering iron. But what fuse is it and where do I buy it? Thank you in advance

ulflundqvist not a fuse but an inductor. That is reference designator L9000 which is a 250 oHm inductor used as a filter. The schematic does not reference the inductance so you will have to do some checking around mouser.com or digikey as well as others.
