My D1 fell from my bed about 5 or so months back and had the dreaded "blank screen" where the backlights as well as the touch screen itself worked, but nothing would show.
After doing a few searches out of curiosity, I read of people fixing this problem by, however bad it may sound, dropping their Droids again. I thought "What the hell. It's a used Droid, already has scratches and dents from its previous owner, isn't under warranty, and I have no use for it anyway. So I dropped it several times from about the distance from my bed to floor (maybe 4 feet or so).
And what do you know! After maybe the 12th drop (like I said, no skin off my nose if it doesn't work), the Motorola insignia showed when I powered the phone back on!
I've been out of the loop for so long, feels good to be back. Decided to put a fresh install of Lithium Mod for the time being until I sit down and start getting my bearings again. Just wanted to share my success story
