I did try to repair myself a few months ago without success. I bought the ribbin $20 form ebay in California. Took the whole cluster aparted, drilled the holes to get access to the trox screws(scarry)....put everything back as instructed on internet, but the end result still not work. So I call the guy and send him the cluster. He even give me $20 cerdit for the ribbin. The whole thing with the repair and shipping took about a week.
