So I found myself in an unfortunately situation about 10 days ago when I saw a very good deal of Samsung Galaxy Tab 10.1 on craigslist. I was told that the tablet touchscreen became completely unresponsive after the guy did a factory reset. He bought it on Ebay, no receipt or anything so was unable to return to the store. He had to sell it cheap to cut his loss. I felt the guy was a little bit tech-challenged and didn't know how to do a hard reset, how to use Odin to unbrick the device and I thought I might be able to do a better job to revive the device. So I just bought it. I tried to get to the recovery mode to do the wiping and factory reset. I connected it to kies and was able to upgrade the OS to ICS. Still when it started up it was stuck at the welcome screen. No matter where I touched NO response whatsoever. I became desperate, I pressed the screen hard. I shaked it quite a bit and I even tried to bent the glass. Nothing. I googled the web and found no satisfactory solutions. At this point I felt hopeless and totally inept. I put the tablet aside and prepared to accept the $100+ loss.
Then 3 days ago I was thinking about doing something about it. Since I pretty much exhausted the software routes the only way I can do is open up the case to see what's wrong inside. I needed a tri-wing screwdriver. I could order it online but I was in a hurry and drove 40 miles to the Fry's store to buy it. When I was back I got the 2 screws out and used my fingernails to open the case. Immediately very obvious the digitizer cable was detached from the logic board. I put it back in its place and wow the screen came alive and I felt on top of the world. The whole process only took about 5 minutes.
For those who are stuck in the similar situations for various reasons the unresponsive screen is most likely caused by the hardware issues. It is worthwhile to take a little bit of risk to open the case. Hey what do u have to lose anyway?
