Picked up a new Duo today. I was purchased as "unreliable". They were right.
On the Super System intro screen, the message "Please Set Disc" is displaying after I hit Run.
There are a few clicks, maybe a bit of a grind, and then that message appears in pink lettering.
Might need a cap job too once it's opened up. I'm just curious if this is going to be an expensive fix.
Thanks.

I doubt it.

Probably just cap job and pot adjustments.

Grinding? Hope it's not a problem with gear!

I don't know if you have tried this yet or not, but try moving your laser assembly all the way to the right, then try to load a game. After I installed my RGB amp, I got the set disc error and this worked for me. If your laser assembly is stuck or frozen well, that's a different story.

on a DUO never move the laser by hand
this will damage the gears

Really? I didn't know that. What I did was I oiled the gears and greased the rails. Then I slowly turned the big gear until the assembly was all the way to the right. Can that cause damage as well?

No, that's the right way

Okay. I should have been clearer about exactly what I did in my post. Sorry about that.

Yep cd pots. Use beemers adjustment by ear guide, it works miracles!

I had this before when I got my Duo-R (it was also sold as unreliable but would play originals about 50% of the time). Adjusted the pots and this made it work most of the time but occasionally it would stop working again. I re-flowed the solder on the joints of the pot on the actual lens unit and haven't had a problem since.
