I went to play my Sega CD today and it would not turn on. The main unit worked but the CD unit just sat there. So I tried my gen 1 sega with it, nothing, cleaned the contacts on both, nothing. So I thought it was strange that boom it just stoped working so maybe there is a fuse. So I looked up sega cd fuse and yup there is one, but it is a strange diode looking thing.
I hard wired the connections between the fuse and boom it worked. The fuse is a Pico II 2.5A which is at http://www.partsexpress.com for about $5 for 5 of them. I was just going to wire/solder up an inline fuse holder so if this happens again it will be easy to replace. I guess if you leave the Sega CD plugged in for a long time the fuse can pop,or if you use an nes power supply. The 10v power supply I guess is the proper one for the Sega CD. There is a video on youtube for this fix.
I just went the solder in a fuse route. ITS ALIVE! ITS ALIVE!!!!!!!
The old F301 fuse in the pic is to blame.
