I have just spent some time pulling apart a newly acquired and faulty NC6000. I read all the forums and the most likely culprit is the max1987 chip. I bought a very fine point battery soldering iron ($20 from dick smith), it had a much finer point than my weller temp controlled station. Using a high power magnifier and a steady hand, I carefully re-soldered each leg of the max1987 chip, reassembled and all was okay for about a day, then the same problem. After pulling it apart again I was looking for why this chip is breaking connections and found that the lcd hinge closest to the heat sink was very stiff. It was so stiff it was causing the case to distort when opening and closing the lid. With the screen removed I carefully placed a little penetrating oil on the hinge and moved it through its full travel to loosen it. It is still firm but not as stiff as it was. I have again resoldered the max1987 chip and reassembled with everything okay again. Hopefully this time it will last.
