Model 1 Sega CD repair help

[CamaroCam]

I have all the right cables for both, and it's just not working. I've fiddled with the expansion port positioning a little bit, and I can get the LED's on the CD to light up for just a second every so often. Is there something I'm doing wrong, or is something broken? Help!

You might have to clean the expansion port. You can think of it as cleaning a cart and the cart slot on a console.

Done. Still not working. I found it with a 17v brick plugged into it, is it possible that someone powered it with that adapter and blew the fuse?

I'd say most definitely.

I think that the fuse is the issue. Doing some research, I've found that to be the most common issue. I'll be ordering a fuse(maybe a 5-pack) soon.

Even with spending a few bucks on a fuse, (I got the console for $4) I'm still way under market value when it comes to the cash I'm putting into this thing.

I'd recommend picking up a multimeter if you don't already have one. You can check the fuse to see if it's good or bad, and take the guess work out of it. If you need another reason to keep a multimeter around, you can use it to check batteries to see how much juice they have left in them.

My favorite budget meter:

Order placed. Thanks for the advice.

Quick Update:

So I bought a replacement fuse, cracked open the system, and switched it out with the blown fuse.

Put it back together, fired it up, and.... it (sort of) works! The Sega CD menu comes up, and that catchy music plays. The reset button opens the tray, and the start button closes it. You can imagine my excitement. I popped in my Abbey Road CD to test it and it spit the disc back out.

I tested it with several music CD's (I don't yet have any SCD games.) It's not even spinning the discs, it's just acting like there is nothing in there. I'm inclined to think this isn't a laser issue, but an issue with the motor or the loading mechanism.

What do you guys think?

The tray probably isn't cranking up fully into position. It could have jumped a gear tooth and needs adjusting, but more likely the belt is worn and needs replacing. If it is stretched out, it won't get enough grip so the tray is never quite pulled fully into place. The system thinks there's a jam and spits it back out.

So, if it is gear tooth miss-alignment I'll just need to adjust it until it hits the sweet spot.

If it's the belt, I'll need to purchase a replacement part and switch it out with the stretched belt.

^^correct?
