Same problem...wish I read this blog sooner about having the digitizer's connection 'flush' when installing... I just replaced six digitizers to six Ipad 2s and the touch screen sensitivity is not there on each of them...the home button works though, which really makes me wonder. I'm hopeful that fully charging them will fix the problem, they've been out of commission for quite awhile

Same problem with an Ipad 2...it's an older model...just now reading this blog about disconnecting the battery first; I wish I read this sooner. It's costing $10 for a replacement digitizer, and this is third time I tried...same problem, the home button works but there's no touch sensitivity
