Sega Cd - Disc not Spinning

Post by **Crabmaster2000** » Tue Mar 18, 2008 11:08 am

My Sega Cd is no longer spinning the disc in order to play games. The system is still recieving power and the main Sega screen displays on the TV so I dont think its a power issue. Someone else had a similar problem with a Saturn in a recent thread and was advised to simply solder the power connecting in the console. Is my situation most likely something similar? He did however have a mod chip and I do not.

I have very minimal experience tampering with electronics so please cut me some slack and make any response very clear and as un-technical as possible. I can handle a simple soldering if thats all it is but if anyone else has any troubleshooting ideas please let me know and walk me threw them while holding my hand. If any other information is required please let me know and ill do my best to provide more. I have no camera right now so pictures will be unavailable at this time.

Thanks guys.

To be more specific/helpful -- is it a model 1 or model 2? top-loading/or tray-loading?

Wow, could I forget a bigger detail. I'm not sure which model number but its the top loading one.

I haven't opened a Model 2, but my Model 1 had some gears with a rubber band that wore out, some PC drives also have it, so try opening if you are feeling brave, while you are there you can also check out for dirt or something jamming the mechanism

Thanks. The system only cost me $10 and I only have one game for it so im not to scared if I wreck even worse, although then ill have to stop playing Sonic CD until I can get a new system. I havnt opened it yet though. I hope its as simple as just cleaning it out. That would be nice.

I had some trouble with the back up battery on my Sega Cd model 2 and the Digipress website helped out quite a bit. It seems that the link isn't working right now, but try later. http://www.digitpress.com

This sega-16 page seemed to have alot of info, but i didn't comb through it to see if it addressed your issue.

From what I remember there isn't a rubber band on the Model 2 because there is no front loading tray. It's just a simple motor that spins the cd, just like an old porttable cd player. Maybe yours died or the solder came loose. They are pretty easy to open, so take a look.

the disc tray for the Model 2 system is very similar to that of a portable CD player... or for the most part, like a lot of consoles from the 90's (I guess they came back to tray loaders with this generation).

the mechanics that make it spin are fairly basic(mechanics is usually the first place you should always look if the system is still booting up fine). There's a pully wheel with a rubberband around another wheel attached to the motor. If this rubberband came off, a simple fix. Can you hear the motor doing something when you turn it on? (you'll hear a whiirrrrrrr, whir, whir, whirrrrrrrrr... kinda like a whisper).

The next more detrimental mechanical problem could be the spindle rod... it is made of like 3 parts all glued together. If any of this little plastic junk broke, you'll need a new one (well the rod is metal, but the rest is plastic). Hopefully this ain't your problem because finding a new one is hard.

aside from those two areas, mechanically there isn't much else to go wrong. Take it apart and look inside, see if anything just looks odd.

if it is more electronic. Then you're in for the fun part! Hope you have a pentometer, solder iron, voltage meter and a steady hand! (though if you can locate symptoms, it will point you in the right direction).
