Mine was dead when I bought it. I asked around and found this. It works great! took about half an hour start to finish to complete. Just grab the back of the computer housing where the little storage hole is, and pull firmly, it is held in with little spring clips. Also, check the other "problem" resistors. I had one that had fallen off completely and was laying in the bottom of the housing, and another haning on by one end. Like he says real hot solder iron for a short amount of time to keep from frying stuff.
