Sega CD Issues

About a week ago I finally after many years acquired a sega cd (model 2). It was unfortunate that it did not come with its power supply but I was determined to get it running. And I had around five genesis consoles so there might have been hope. Researching online I came to find out both the model 1 and 2 sega cd could be powered using the black tip genesis model 1 power supply. A solution had been found and I could finally check out this relic of the past. I plugged in both the CD and my genesis, turned it on and suddenly smoke started coming out of the power supply being fed to the sega cd. I cut the power to my surge protector and removed it from the system. And now I'm stuck in a rut. I've looked online for anything similar to this incident but cannot find anything regarding this issue. Was it just a bad power supply, or the system itself? Any kind of suggestions or help would be appreciated in light of my current situation.

  • Do you have another power adapter to try? Sounds like the wall wart had a transformer issue / went bad.
  • Are you sure you used a genesis adapter and not an nes ac adapter. The nes adapter will do that to your system. It is possible to fix but you probably need a few new fuses.

    That's what I think it is too. Even before the sega cd it would get hot after only an hour of use.

    I would be kicking myself in the ass if I had used an nes adapter lol.

    That’s where I would start. If you need one, I can see if I have any spares. 



     
  • Could bad capacitors also be culprit to an issue like this?

    How did it go?
  • Put in another model 1 adapter into my serge protector and plugged it into my model 2 sega cd. As i predicted it cooked the adapter within seconds. Not sure what the hell is going on but it has nothing to do with the adapter.
  • Sucks cause i just picked up a copy of Spider-Man and the Kingpin.
  • can i play?

    I dont know, can you fix a very stubborn sega cd?
  • sounds like your system is a kamakaze

    I find it easier to compare it to frankenstiens monster. Because tommrow im taking this SOB apart and finding out if the board looks like a grenade went off inside.
  • are you sure you're using the right adapter? it should be mk-1602. the genesis 2 uses a different adapter with reverse polarity.



    it's strange that the adapter is failing. usually the fuse on the sega cd board goes out and just nothing happens. maybe you have a short on the scd board
  • With the common blown fuse issue someone may have bypassed the fuse. Usually there is nothing actually wrong to explain the blown fuses but it sounds like there may be in this case. If they did bypass it then it's dumping more power than the fuse would normally allow through some other defective component. This will, of course, put a huge load on your adapter.  
  • Give us an update OP. My curiosity is curious.

    I will be opening the system up tommrow and post pictures. Im no expert when it comes to repairs or knowing what to look for. But the system was free so hopefully the repairs wont cost more than just outright buying a working system.

    I have burned through two mk-1602 adapters. The site i had used "http://www.gametrog.com/GAMETROG/How_which_do_i_need_SEGA_AC_Power_Supply_Information_Specs_Model_mk-3025_mk-1602_mk-2103_mk-1479_mk-4122_aa-s95j.html" had listed this as the preferred adapter to run the sega cd model 2 outside of owning the official sega cd adapter.
  • Wow, that's pretty crazy. Did you eventually find the right adapter to make it run?
  • Buy a new sega cd

    Wow, I wish that were true.  A Sega CD is pretty high on my own list, as there's a bunch of games on it I want to play.  Hopefully, I won't have these kinds of issues!

    I would recommend a CDX if you are going to get a Sega CD. I have a model 1 which I got in the late 90s, and after the first couple years it has had constant problems.    





    Happy Birthmas, OP!
  • ^^^CDXs are super expensive these days. Cheapest is SegaCD 2. Ironically I think they're the most reliable.



    I don't think it's the adapter. I think it's something inside the SegaCD. It sounds like the voltage regulator or something has shorted.
  • I'd like to get a CDX eventually, but I'm probably going to start with the model 2, since they're much more common and economical. Also, I want to hook up a 32X to my system, and I *think* it's not compatible with the CDX.
  • 32x is compatible with the CDX
