i also now have what looks like little cracks just under the screen, it was slammed downwards on my table ,the glass is not broke however & blue light only & no reboots working (which i know from experience was there first thing. I'm so upset my baby pictures since birth !! what to do ??? puzzled as i don't know how to tell if its the ldc screen inside or a different damage.
