What is it that's actually wrong with it? Are you sure your PSU is good and providing 12V correctly? Have you tested with another floppy drive? What happens when you connect an external floppy drive (especially one with external power if you have one)?
There's a bunch of capacitors on the floppy port - I've seen these go kablooie and short circuit before now (I'm talking about the ceramics, not the electrolytics here - but those should be changed as a matter of course).
If you can tell use the symptoms, perhaps we can get it running again - but it's fairly unlikely to be the controller because the controller is pretty fundamental to the rest of the system (which I presume works ok!)
