I've just recently busted a screen hinge on my Ti667, and ordered a part through PBMedic. The take-apart instructions were terrific, and guided me through the entire procedure.
However, as I'm reassembling, I find that the orange cable connecting the trackpad to the motherboard doesn't want to stay attached. The cable appears to be a little too long, so it is overreaching. Perhaps this is why it's covered in kapton? The other nearby cables (HD, DVD) connect just fine, so I don't think I put the motherboard in incorrectly. The trackpad cable just keeps "popping" off due to the curve of the cable. I thought that the HD might help in pressing this cable down, but it does not.
Any ideas on this? Will the bottom panel press this securely in place? I am still assembling the machine (and typing this message on another), so it may not be an issue, but it's so unwilling to stay attached that I expect it will be an issue quickly.
