Ask general Genesis/MD/Sega CD/32X questions here (for new members)

i don't know if that's it..

can you take a picture? im not at my SCD2 r2 board right now (it's 15 miles away)

I hope you can make out what's going on in the pic. I outlined the resistor that i was talking about...

i do believe that's it..

if you have a multimeter, check the continuity..

evildragon you seem to be the authority in these parts on the Sega CD, how much have you seen the unit going for:

a) In stores?
and
b) On auction sites?

Your input would be appreciated

I do not possess a multimeter. Is there any other way to check?

I'm not too sure on price, but for in store like gamestop, if they had one, it probably would go for 60 dollars.

for ebay and stuff, I got one for 30 bucks..

There's not really any other way.. To even fix it however, you will need a soldering iron, and know how to solder.

Thanks for the info evildragon

Hey there, i used a continuity tester and the circuit seems open. What kind of fuse does this bad boy take?

no clue, i'm going to take a long shot and say over 800ma, but under 2amp..

Greetings-

I recently purchased a 'make an offer' deal on a Sega lot. The Sega CD appears to have some issues (clues me in why it wasn't priced). When I turn it on it makes a grinding sound.

After dismantling I narrowed it down to the motor is stripping the gears. I am guessing it thinks the laser needs to return to the beginning at powerup but its confused and its forcing the laser to back making the gears grind.

I thought maybe it was out of line and needed adjusted. Sometimes it works but most of the time it doesn't. It will still play the discs its just confused and it just doesn't seem to be good on the motor. (laughs)

Is this shot or does it need re-aligned?

Thanks!
Erik

It would help to know which model Sega CD this is, a model 1 or 2? Mechanically they are different.

If a model 2, when the laser returns to it's initial position (inner part of CD), it hits a little "switch", to tell the controller that it reached it's position. Makes sure this switch isn't worn down or dirty.

Greetings-

Its the Model 2 version - I see the switch - In order to get to it to get a closer look I need to remove the spindle the cd sets on.

How does this come off?

Thanks!
Erik

no, you don't need to remove the spindle, you can easily access it via the side of the laser assembly...

The switch looks like two poles protected by a clear plastic, just makes sure when the lid switch is closed that this retracts, and as soon as the laser hits it, it stops..

I had that problem on my original sega cd 2. the original switch just wouldnt work reliably after trying to clean it. I ended up adding a cherry microswitch in there and adjusted the actuator to work as the limit switch. I think its buried in storage but I could dig it out if anyone wants to see a pic of the repair.

DO NOT USE the sega cd till u get this fixed! it will do permanent damage to the gear if u do.

Hi, I wish to post a new thread about a Megadrive/Genesis hookup technical problem... but the Forum here won't let me post a new thread? I signed up last week....
I would post my Megadrive/Genesis problem in this thread but it's rather long. :(

Can anyone help please? Thanks.

P.S. My apologies.... I've just realised I posted this in the SEGA CD thread, not MD/GENESIS thread... Sorry. :bang: :confused:
