I've got two Duo's and each has their own problems, anyone with experience at repairing a Turbo Duo's have any suggestions?
Duo #1 was one I attempted to repair by doing a HOP-M3 swap out. After doing the swap I got the first test disc to work (very slowly) and then nothing. I still have both laser assemblies (the original and the replacement).
Duo #2 requires about 5 minutes before CD audio kicks in. Other than that it's fine. Obviously repairing it is a lot less of a priority. I'm guessing this one is probably just a cap replacement but if any other ideas are out there let me know.
-
Both likely need cap replacements. The one that you swapped the laser on probably needs the pots adjusted as well. Grinding/whining/whistling?

It just says "please insert disc" on the one I swapped the laser on. No other major noises. It doesn't seem to want to spin the discs.

Does it "click", like the laser gives it a try and can't focus? Then it almost definitely is a pot problem, though the caps can easily be problematic. Do you see and corrosion/fluid around the caps or any IC?

I didn't notice any corrosion. I've also successfully changed out Playstation and Dreamcast lasers. But it could be a pot problem. I may wind up seeing if anyone on here would want to take a look at it.

Would taking a picture of the inside of Duo #1 help?

Sure. Try to get the area south of the laser unit especially.

Sure.

Let me know if you need a better shot, Photobucket also decided to resize these.

D-Lite's right, probably a cap swap on both, and a pot adjustment on #1.
D-Lite would be my first choice for any Duo work, but if he ends up not being able to do it, lemme know. I've resurrected several units over the last year or so. ;-)

Got your PM, glad I could fix it for ya. Lemme know if you'd like the caps done on #2 down the road.
Cheers!

Good job boss :)

I may, #2 isn't experiencing the problem consistantly (maybe only half the time I plug it in does it experience the problem). But I may.
