First, I was given a frozen Kindle 3. I’ll call this Kindle A. I thought I was brilliant when, through much searching of this forum, I revived it, most recently using Kubrick, a great tool for installing a fresh O.S. (flashing the firmware). So, when I friend reported that his Kindle (Kindle B) was frozen, I gave him my resurrected one, which promptly froze on him. In the meantime, I did everything possible to revive his – his screen was frozen in negative, no signs of damage. When nothing worked (again, Kubrick was used to flash the firmware), I assumed the screen of Kindle B was the problem. In retrospect, I see how faulty my reasoning was – even a cracked screen will show some change when the Kindle is unfrozen.
Next step: take the good screen from Kindle A, and put it in Kindle B. I wasn’t careful removing the negative screen and broke it, because, or course, it was already broken, right? Wrong! Once installed in Kindle B, the good screen from the Kindle A is frozen. So now I have two broken Kindles, and, to top it all off, I had ordered a replacement screen. So I’m left with two good homeless screens.
Also, I realized that one can try out a new screen without going to all the trouble of pulling the Kindle 3 apart. One can simply remove the back, disconnect the screen cable, and plug in the replacement – the cable is long enough. I could have saved myself the eye strain of removing and reinstalling all of those tiny screws (which I did several times, just to make sure). Short of embarking on a detailed study of the circuit board, I think I’m done.
Edit: I ordered a replacement motherboard from here:

Installed, works perfectly. No trouble registering, etc.
