Update, fwiw: After trying gingerly to get a foothold for my library card to start cracking the case open for about 10 minutes, I got cold feet. Then I remembered that some people on this thread tried massaging their device and got the digitizer back that way. So, for about 5 minutes or so I gently massaged the edges of the device, where I guess-timate the cable might be based on watching Meso's videos. I powered up, and the pen has been working again. I don't know how long this will last. I will change my vote in the poll.
