Well, I followed dedtech's advice. I switched power plugs and the thing works! I feel really stupid that I was about to pry the thing open and do some soldering when all it needed was a good power cord. I sometimes forget to start with the simpler things first. Thanks dedtech.

In relation to replacing the fuses on these systems, does anyone know or have access to schematics of the Sega CD/Genesis combo unit (I do not know which model I have)? I have seen a lot of these not functioning and I'm wanting to restore some of them.
