I'm willing to send it to anyone who thinks they can figure out what's wrong. That's not an issue. I'm based in SE Michigan.

Unfortunately I don't have a scope, just a really crappy volt meter.
I think I've done about as much as I can on my own. I'm going to send this off to a friend who thinks he can fix it. I'll report back when I get some news. I appreciate everyone's help and I'll pass along this info to my friend.

Ok that's what I suspected as well. Someone told me that if the laser doesn't detect the disc it won't spin.
Which wire controls the flagging of the mirror pin? I thought I tested all the wires in the two ribbon cables and they all tested fine for continuity. The only one that I'm not sure about is the larger yellow wire that appears to go from the motherboard into a taped up area of the wire bundle. I don't know where it ends so I couldn't test it for continuity.
Where is the CXA1081? Is is easily replaceable or is it soldered in?
Quotepossible causes laser/wiring/CXA1081I think we can eliminate the laser because even if the new laser was bad, the old laser which worked before is no longer working. I can't believe I could have damaged it taking it out of the system.

It's hard to see, but from what I can tell the laser bobs two or three times before giving up and saying Set Disc. I don't think it's locking on after one bob.

Ok I think I see it. The sled does bump that switch, but it doesn't look like it pushes it in very far. I moved the sled over so it totally pushed the switch in, but still no spin. How much does it normally push that switch in?
EDIT: Looks like that switch just makes the laser go back to the left. I held it in and the laser went all the way the other direction. So that would make sense if it only bumped the switch lightly and bounced back a bit.
I did a continuity check on the two wires going to that switch. They seem alright.

Yes it does all that. I assume by 'center switch' you mean the cd spindle?

I did go through the guide here first, but nothing helped. I really REALLY don't want to adjust the pots as I hear you can screw crap up that way and they worked with the old laser anyway. I did play with the pot that supposed to control the CD spindle, but I put it back to where it was after that didn't do anything and the CD wasn't spinning before anyway so I don't think that could have done anything. I never touched the pots before that.
I got the laser off ebay from the seller a lot of people get theirs from (he's from the USA, that's all I remember). However if it was a bad laser or pot setting I can't see why the old one wouldn't work, that's the mystery. To me that points to bad or broken wiring, but I did a continuity test on the wires and they all seem ok as far as I can tell.
I tried a music CD but it still won't spin. What wires control the CD spinning?

Yes that's correct. The old lens not working is what's really stumping me.
Pictures. Note that the board to the left is a RGB mod and has nothing to do with the laser (everything including the RGB mod was working before I tried to install the new laser).

Ah. Thank you to whoever moved the thread, I didn't realize there was a separate repair section.

Do you know which pots you adjusted? I played with VR105 (spindle comp) but that didnt seem to do anything. Also, why would I need to adjust the pots if everything was working before? If the new laser with the pot positions was a problem, you'd think that putting in the old laser would solve that.
I'm very nervous about playing with any of the pots as I hear it's almost impossible to get them adjusted right if you screw it up.

Console Repair/Mod Center / Help! The CD Won't Spin on my TurboDuo!

Hi,
I've just completed the laser replacement on my US TurboDuo and everything went very smoothly (or so I thought). However no matter what I do the CD will not spin and eventually I get a Set Disc error. I did a basic continuity test on the wires and they all seem good (at least I think). On a hunch I put my old laser back in and it also will not start spinning the disc. The old laser was working just fine before I put the new one in (although it would not read CD-R's which is why I replaced it) so I can't understand why it won't work now.
Since both the old and new laser don't seem to be detecting the disc I guess I must have broken something when I removed the laser. I can't see what I could have damaged as it was very simple and I followed the guide. The Duo has been freshly recapped so that can't be the problem. On a whim I even tried adjusting the pot that controls the CD spindle but that did not help. Any ideas? I'm at my wits end with this thing. I think I may need to send it to someone for repairs.
