Sharp Twin Famicom Drive issue

[Mosdef]

Hi all, I have just joined and excited I finally got an ST Famicom.
I just received this little beauty and it had a new belt installed from previous owner and he told me he couldn't get the drive to work either.
I opened up the FDS and all it was doing is reading the disc over and over again.
I decided to clean it up and do all the adjustments from this forum and from some youtube channels, re installed and it is still doing the same thing, won't even pop up with an error code on the tv even after running the disc for over 20 mins.
I have looked everywhere for a solution and nothing is coming up with a remedy.

One person has put up on youtube my exact same problem and nobody has given him an idea either!

I really hope someone can help me out or has had the same problem and got it working.
Thank you in advance

that's not good. so it is starting but not showing up any error?

I'd change the capacitors as a start and see from there.

Or you can buy a cheap loose Disk system and swap the components.

Hi Nihonmasa, Yes unfortunately it shows no error at all it just sits there and reads the disk then starts again over and over.
Not sure what capacitors your saying to replace? I just changed the 2200 uf 16v capacitor on the power board because it was cracking open, I looked at the smaller ones on the same board and the are fine  with a visual inspetion (Not cracking or puffing up)
I've been looking everywhere for a loose or FDS system here in Australia and the don't come up very often

I'm in the SA, I have loose disk systems but none of them work, different to your problem though, probably just calibration.

Hey Phreak97, Good to see a fellow Aussie on here! Whats the problem with your drives and how many do you have? LOL

I have actually found what my problem is today, a part of a switch on the actual drive motherboard has broken off that tells the drive when to stop, there are 3 switches on the floppy MB and the one in the middle is the culprit....

Haha I'm down to 3 which didnt work after a belt change.
One was taken apart without marking the gear positions then had the spindle position and the motor speed messed with.. That one reads some disks. The others throw errors every time even though the spindle position should be at factory. I don't know their prior history though.
I also have a twin famicom which is working perfectly.

You can probably get a tiny microswitch and hot glue it into place if you can't get the orignal type switch anywhere.
