Twin Famicom making buzzing noise when disk card is set. Needs New Belt?

[gamemaster14]

I had bought a Twin Famicom off of ebay a month or so ago. I had been waiting for a disk card game to come in for over a month from Japan. Today I hooked up the system, flipped the switch to the disk side, inserted the game. The system says loading but all I hear is a buzzing noise and the game never loads. Could the belt need to be changed?

 

The cartridge games work fine.

 

Any help would be appreciated.

If it wasn't advertised as having a new belt then that's the likely culprit.

The seller didn't seam to know, I just wanted to know if the buzzing sound and failure to load are common symptoms of a bad belt as this is my first experience with Famicom Disk.

Unfortunately the original belts are a guaranteed to fail item. The buzz may be due to a bit belt remnant stuck to the motor pulley.

 

There is a lockout solenoid that prevents insertion of cartridges when in FDS mode but I doubt that's the source of the buzz.

The buzz only happens when a disk is inserted so I would think (not sure of course) it would have to be some part of the disk assembly making that noise.

 

If no disk is inserted I just see Mario and Luigi hitting the bottom of the sign changing the color.

Replaced the belt, at first got an error 21, tried cleaning the head no change. Noticed the belt was twisted so I untwisted the belt and put it back together. Unfortunately now the drive doesn't power up or move at all. The system just says Loading and nothing ever happens. Could I have broken something? Is there a common thing that would make this happen, some plug not connected? Any help would be appreciated.

I have also recently purchased a Twin Famicom and I have exactly the same problem.

 

Did you manage to fix the problem? I would be grateful if you have any information how to fix this problem that you can share.
