Apparantly there is some Sega CD's that have a completely different fuse on the bottom of the circuit board. It is a different looking fuse, but it has the same specs. I replaced it with the PICA ii fuse and it works perfectly.
No Pica ii fuse on top like the majority of Sega CD's have

Its on the bottom side

Close up of the dead fuse on bottom, looks different but its still a 2.5

Brand new Pica ii fuse installed

Success!!
