The same thing happened to me. It would not turn on at all. My Viewfinder would not pop up and when I charged it a red light would turn on and then it would turn white but still nothing. I tried to reset it to with a pin. Nothing worked. I even connected it to my computer and it would not read it to download the new firmware. FINALLY I tried to push onto the viewfinder again and tried to see if anything was stuck in there all around the edges. I pushed on the edges trying to get it to pop up manually and it worked. The viewfinder popped up and the whole thing lit up. Now it is charging and the 3 red flashing lights are on. My computer also detected it. So you may need to manually get the viewfinder to pop up since that is what turns it on.
