I was doing a few minor settings changes. When I hit the return, the screen went black and the unit apparently froze (on the black screen.. I powered off, then restarted, but it hung on Hello in the display. I unplugged the coaxial DC plug, waiting a minute (or maybe slightly less) powered back up, but the same thing. I do hear some HDD activity initially, but the stops after a couple of minutes.. I was going to try to flash the latest F/W, but I wanted to see if that was ok or was there something else I could do. I don't remember the F/W version I was running, it was at least before last summer. The is a HDD in the player that I loaded some more media files. None were playing when I was in the settings menu. Right now it'sbeen in this hung mode for probably 10 minutes, with no change. The on-screen display is NOT frozen, it still has it's animation. Ideas please.
